Lightning dock geothermal space heating project, Lightning Dock KGRA, New Mexico. Final report  

DOE Green Energy (OSTI)

The proposed project was to take the existing geothermal greenhouse and home heating systems, which consisted of pumping geothermal water and steam through passive steam heaters, and convert the systems to one using modern heat exchange units. It was proposed to complete the existing unfinished, re-inforced glass side wall, wood framed structure, as a nursery lath house, the purpose of which would be to use geothermal water in implementing university concepts on the advantages of bottom heat to establish hardy root systems in nursery and bedding plants. The use of this framework was abandoned in favor of erecting new structures for the proposed purpose. The final project of the proposal was the establishment of a drip irrigation system, to an area just west of the existing greenhouse and within feet of the geothermal well. Through this drip irrigation system geothermal water would be pumped, to prevent killing spring frosts. The purpose of this area of the proposal is to increase the potential use of existing geothermal waters of the Lightning Dock KGRA, in opening a new geothermal agri-industry which is economically feasible for the area and would be extremely energy efficient.

Geology and geothermal waters of Lightning Dock region, Animas Valley and Pyramid Mountains, Hidalgo County, New Mexico  

DOE Green Energy (OSTI)

This circular covers the geology of the Pyramid Peak, Swallow Fork Peak, Table Top Mountain, and South Pyramid Peak 7-1/2-min quadrangles, which include the Lightning Dock KGRA. Hot wells (70 to 115.5/sup 0/C) seem to be structurally controlled by intersections of the ring-fracture zone of an Oligocene ash-flow tuff cauldron (Muir cauldron), a Miocene-to-Holocene north-trending basin-and-range fault (Animas Valley fault), and a northeast-trending lineament that appears to control anomalously heated underground waters and Pliocene-Pleistocene basalt cones in the San Bernardino, San Simon, and Animas Valleys. The Muir cauldron, approximately 20 km in diameter, collapsed in two stages, each associated with the eruption of a rhyolite ash-flow-tuff sheet and of ring-fracture domes. Most of the hydrothermal alteration of the Lightning Dock KGRA is related to the first stage of eruption and collapse, not to the modern geothermal system. Contrary to previous reports, no silicic volcanic rocks younger than basin-and-range faulting are known; unconformities beneath rhyolite ring-fracture domes are caused by Oligocene caldera collapse, not by basin-and-range faulting. The Animas Valley is the site of widespread post-20 My travertine deposits and near-surface veins of calcite, fluorite, and/or psilomelane, controlled by north- or northwest-trending basin-and-range faults. The fluoride-bearing waters of the Lightning Dock KGRA may be a late stage of this hydrothermal activity. Distribution of Pliocene-Pleistocene basalt suggests that deep-seated basalt near the solids may be the ultimate heat source.

Eisenbeis, Supt. of Conservation LIGHTNING Because we are so rapt up with our modern inventions, we forget that primitive man, ages before the beginnings of civilization, made one of the greatest discoveries of all time -- the use of fire. However, for thousands of years before he learned to kindle his own fires by friction or by striking sparks from flint, he snatched flaming firebrands from forest fires started by lightning. These he carried away and carefully fed with dry wood, year in and year out, to warm his cave, frighten away wild beasts and cook his food. Around the world, in every year, countless thousands of fires are started by lightning.

Characterizing wind turbine system response to lightning activity  

DOE Green Energy (OSTI)

A lightning protection research program was instituted by National Renewable Energy Laboratory to minimize lightning damage to wind turbines and to further the understanding of effective damage mitigation techniques. To that end, a test program is under way to observe lightning activity, protection system response, and damage at a wind power plant in the Department of Energy (DOE) and Electric Power Research Institute (EPRI) Turbine Verification Program. The authors installed Lightning activated surveillance cameras along with a special storm tracking device to observe the activity in the wind plant area. They instrumented the turbines with lightning and ground current detection devices to log direct and indirect strike activity at each unit. They installed a surge monitor on the utility interface to track incoming activity from the transmission lines. Maintenance logs are used to verify damage and determine downtime and repair costs. Actual strikes to turbines were recorded on video and ancillary devices. The test setup and some results are discussed in this paper.

Analysis of cloud-to-ground lightning in Hurricane Andrew  

E-Print Network (OSTI)

In August of 1992, Andrew joined a long list of tropical storms that have caused considerable damage and loss of life as they made landfall near a populated area. However, Andrew was unique in the sense that no previous landfalling tropical storm in the United States has provided such an excellent opportunity to study the cloud-to-ground (CG) lightning associated with this type of storm. While numerous thunderstorm systems, particularly the severe storms of the Great Plains, have been studied for lightning characteristics, the ability to conduct similar studies on hurricanes has been limited due to the small number which have occurred since the relatively new National Lightning Detection Network has been operational. 17,036 CG strikes over a 77 hour period were attributed to either the eyewall region or the primary spiral rainbands of Andrew. The overall distribution by polarity of the lightning was found to be 2.1% positive and 97.9% negative. As the storm was dissipating over land in Mississippi all lightning observed near the pressure center was positive. Throughout the lifetime of the storm, the negative first stroke peak current decreased while the positive first stroke peak current increased. The mean multiplicity of the negative flashes was 2.6, while the positive lightning had a mean value of 1.2. High-multiplicity flashes (negative CG flashes with 10 strokes or greater) tended to occur in four distinct groups and in time intervals of 19 to 23 hours apart in an area corresponding to the right-forward quadrant to right flank of the storm structure. Comparison of radar data to the lightning data shows that the deep convective regions of the outer rainbands were the areas with the most lightning. A lack of significant lightning observed in the eyewall region is consistent with previous research suggesting microphysical processes in this part of the storm are not favorable for charge separation.

New mechanism for lightning initiation  

Science Conference Proceedings (OSTI)

This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). To distinguish radio-frequency (rf) signals generated by lightning from the electromagnetic pulse produced by a nuclear explosion, it is necessary to understand the fundamental nature of thunderstorm discharges. The recent debate surrounding the origin of transionospheric pulse pairs (TIPPs) detected by the BLACKBEARD experiment aboard the ALEXIS satellite illustrates this point. We have argued that TIPP events could originate from the upward propagating discharges recently identified by optical images taken from the ground, from airplanes, and from the space shuttle. In addition, the Gamma Ray Observatory (GRO) measurements of x-ray bursts originating from thunderstorms are almost certainly associated with these upward propagating discharges. When taken together, these three measurements point directly to the runaway electron mechanism as the source of the upward discharges. The primary goal of this research effort was to identify the specific role played by the runaway-air-breakdown mechanism in the general area of thunderstorm electricity and in so doing develop lightning models that predict the optical, rf, and x-ray emissions that are observable from space.

Thermo-Bimorph Microciliaarrays For Small Spacecraft Docking  

E-Print Network (OSTI)

Microelectromechanical system (MEMS) technology promises to improve performance of future spacecraft components while reducing mass, cost, and manufacture time. Arrays of microcilia actuators offer a lightweight alternative to conventional docking systems for miniature satellites. Instead of mechanical guiding structures, such a system uses a surface tiled with MEMS actuators to guide the satellite to its docking site. This paper describes an experimental setup for precision docking of a "picosatellite" with the help of MEMS cilia arrays. Microgravity is simulated with an aluminum puck on an airtable. A series of experiments is performed to characterize the cilia, with the goal to understand the influence of normal force, picosat mass, docking velocity, cilia frequency, interface material, and actuation strategy ("gait") on the performance of the MEMS docking system. We demonstrate a 4 cm 2 cilia array capable of docking a 45 gram picosat with a 2 mm 2 contact area at micrometer precision. It is concluded that current MEMS cilia arrays are useful to position and align miniature satellites with up to several kg of mass.

The convective structures associated with cloud-to-ground lightning in TOGA COARE Mesoscale Convective Systems  

E-Print Network (OSTI)

The TOGA COARE experiment was carried out in the western Pacific warm pool region from November 1992 through February 1993. Data from TOGA COARE provide the opportunity for comprehensive studies of tropical oceanic convection. This study seeks to understand more about the structures of tropical mesoscale convective systems in relation to their lightning activity and cold cloud area. The properties of convective cores within the MCSs, as well as their infrared (IR) cloud top temperatures are related to cloud-to-ground lightning. IR and lightning time histories for each case are compared, and the cases ranked by mean flashes per 10000 km2. For selected cases, radar/lightning overlays and vertical profiles of maximum radar reflectivities (VPRRs) are shown in order to describe the convective structures of cells that produced lightning, and also cells that did not produce lightning. IR cloud-top temperature and lightning histories indicate the highly variable nature of the TOGA COARE MCSs. Some MCSs which have very cold cloud-top temperatures have little or no lightning. When a system did produce lightning, more flashes generally occurred during its growth phase. Overall, IR measurements seem to be a poor indicator of lightning due to the lack of a clear relationship between the size of cold cloud-top area and cloud-to-ground flashes. The overall flash rates of the TOGA COARE MCSs support previous work which showed that tropical oceanic convection has an order of magnitude less cloud-to-ground lightning than continental convection. In fact, the highest flash rate for the 13 cases was less than the weakest continental case in a Texas MCS study (Toracinta et al. 1995). Examination of individual VPRR and of all convective VPRR from the 13 cases indicate a pronounced difference between lightning producing and non-lightning producing cells. Lightning producing convective cells have higher radar reflectivity in the 5.0- 8.0 km layer, and a slower decrease with height, both observations indicating larger ice particles in the mixed phase region between 00 C and-200 C.

Lightning location characteristics and vertical structure analysis of isolated storm cells in the TOGA COARE region  

E-Print Network (OSTI)

Previous studies have investigated the difference in structure between continental and oceanic storms, and tropical versus mid-latitude storms. This is the first study that has investigated the differences in vertical structure between lightning producing storm cells, and non-lightning producing cells over the tropical oceans. The characteristics of lightning locations with respect to radar reflectivity were also examined. Lightning characteristics of flashes associated with TOGA COARE storm cells were examined. One hundred fifty-three flashes were detected by three direction finders within the study area, a 150 kilometer circle around the Vickers research vessel. Radar reflectivities and reflectivity gradients were compared to flash counts. It was found that lightning flashes tended to occur in the convective region (the region enclosed by the 30 dBZ contour) with a peak at 37 dBZ, but avoiding the highest reflectivity values. Flashes often occurred in reflectivity gradients higher than 3 dBZ/km at 2 and 5 kilometers, which is the likely position of an updraft-downdraft interface. Isolated storm cells from four days during TOGA COARE were analyzed. Mean vertical profiles of radar reflectivity (VPRR) were constructed; these profiles were compared with other VPRRs from other tropical oceanic storms, and tropical and mid latitude continental storms. Reflectivity lapse rates were found to be effective in discriminating between lightning and non-lightning storms. A connection between the amount of lightning flashes and characteristics of VPRRs was examined. It was found that lightning and non-lightning storm cell VPRRs were associated with lower reflectivity lapse rates than ever previously been found for tropical oceanic storms. Reflectivity lapse rate of the mean profiles of lightning storm cells was 3.32 dBZ/km versus the 4.33 dBZ/km found for non-lightning storms. Lightning storms had reflectivity lapse rates similar to 3.5 dBZ/km lapse rate of tropical continental storms studied by Zipser and Lutz (I 994). Lapse rates of non-lightning cells significantly exceeded lapse rates from other cells in different tropical oceanic regimes.

Cloud-to-ground lightning characteristics over Houston, Texas  

E-Print Network (OSTI)

The U. S. National Lightning Detection Network (NLDN) has recorded cloud-to-ground (CG) lightning observations regularly for more than a decade (1989-2000). The main research focus using the recorded NLDN data has been the creation of lightning climatologies (e.g. Orville and Huffines 1999). These climatologies have revealed important results that indicated certain patterns of lightning behavior across the U. S. One of the most significant findings from such work has been the observance of lightning "hot spots" over and near cities (Westcott 1995). Houston, TX is one such "hot spot," with significant enhancement (45%, all 12 years) of lightning activity observed over and downwind of the urban area. Enhancement varied based on season and time of day, with the greatest enhancements occurring during the summer (58%) and the late morning/afternoon time periods in each season. Two other interesting features discovered during this study included a decrease (-12%) in the percentage of flashes lowering positive charge to ground over the city, and significantly larger values of negative median peak current measured along the coast and well into the Gulf of Mexico. One hypothesis proposed for explaining the Houston enhancement includes the complex sea breeze and associated low-level convergence that result because of the proximity of Galveston Bay to the southeast of Houston. Also, there are a multitude of factors associated with a large city such as Houston that can modify the local climate. Some of these urban factors include: increased cloud condensation nuclei (CCN) concentrations, especially from industrial pollution, the urban heat island, and frictional lift. It has been proposed by Rosenfeld and Lensky (1998) that the large quantity of CCN in polluted areas can enhance a storm's electrical state because they act to decrease the coalescence and rainout cloud processes, therefore allowing more supercooled liquid water to exist within the storm. The urban heat island can enhance thunderstorm initiation through increasing the low-level mesoscale convergence and upward motion directly over the city. The observations showed support for each one of these aspects to be a factor in enhanced lightning activity over Houston.

Computational methods for molecular docking  

Science Conference Proceedings (OSTI)

This tutorial was one of eight tutorials selected to be presented at the Third International Conference on Intelligent Systems for Molecular Biology which was held in the United Kingdom from July 16 to 19, 1995. Recently, it has been demonstrated that the knowledge of the three-dimensional structure of the protein can be used to derive new protein ligands with improved binding properties. This tutorial focuses on the following questions: What is its binding affinity toward a particular receptor? What are putative conformations of a ligand at the binding site? What are the similarities of different ligands in terms of their recognition capabilities? Where and in which orientation will a ligand bind to the active site? How is a new putative protein ligand selected? An overview is presented of the algorithms which are presently used to handle and predict protein-ligand interactions and to dock small molecule ligands into proteins.

Cloud to ground lightning in tropical cyclone: a study of 34 West Atlantic tropical cyclones from 1986-1996  

E-Print Network (OSTI)

Cloud to ground (CG) lightning characteristics and patterns were investigated for 34 tropical cyclones for the time period 1986 to 1996. Spatial analysis of CG lightning relative to both compass directions and the direction of motion were compiled. Additionally, a radial analysis of this data was performed within both a 300 km radius and a 50 km radius range. Finally, all analyses were stratified into all tropical cyclones and hurricane categories for further consideration. The National Lightning Detection Network recorded 307,593 CG lightning flashes within 300 km of the storms in this study. Negative flashes had an average first stroke peak current of -49 kA and a mean multiplicity of 2.7. Positive flashes occurred at a rate of 5.3 percent, with a mean peak current of 43 kA and 1.2 multiplicity average. Detected CG lightning characteristics changed significantly with a network upgrade in 1994. CG lightning flashes for all tropical cyclones favored the area south and west of the cyclone center. However, taking into account storm relative motion, the majority of flashes shifts to the front and right sections of the storm. Radial plots indicated lightning frequency increased throughout the domain, with a maximum between 270 km and 300 km. Hurricanes, however, indicated flashes occurred most often in the north and east quadrants. When adjusting for storm motion, the activity shifts to the right with some evidence of individual rainbands in the rear section. Radial plots indicated the increased organization of hurricanes, with a weak maxima in the convective eyewall, a minimum in the stratiform area, and a strong maximum in the outer rainbands. Further analysis indicated a higher frequency of CG lightning flashes in hurricanes suggests a state of hurricane strengthening or weakening. However, there was no direct correlation in the observed lightning frequency with a given change in the central pressure of the hurricane.

The response of aeroshells to lightning  

SciTech Connect

Electrical discharges from a lightning simulator were directed at Mk12 aeroshells. Buckling of the aluminum substrate was observed after some 100-kA shots, and severe damage consisting of tearing of the aluminum and the production of inward flying aluminum shrapnel was observed after some 200-kA peak-current shots. Some shots resulted in severe damage to both the aluminum and the carbon-phenolic ablative material. It is reasonable to conclude from the experimental results that a lightning stroke with very high-peak current could, by itself, produce an opening in an Mk12 aeroshell. Because the aeroshell is part of the nuclear explosive safety exclusion region for the Mk12/W62 nuclear weapon, an opening would significantly reduce the assured safety of the weapon. It is unlikely that the observed interaction between lightning and the aeroshells would have been predicted by any form of computer simulation.

Thunderstorm and Lightning Studies using the FORTE Optical Lightning System (FORTE/OLS)  

Science Conference Proceedings (OSTI)

Preliminary observations of simultaneous RF and optical emissions from lightning as seen by the FORTE spacecraft are presented. RF/optical pairs of waveforms are routinely collected both as individual lightning events and as sequences of events associated with cloud-to-ground (CG) and intra-cloud (IC) flashes. CG pulses can be distinguished from IC pulses based on the properties of the RF and optical waveforms, but mostly based on the associated RF spectrograms. The RF spectrograms are very similar to previous ground-based VHF observations of lightning and show signatures associated with return strokes, stepped and dart leaders, and attachment processes,. RF emissions are observed to precede the arrival of optical emissions at the satellite by a mean value of 280 microseconds. The dual phenomenology nature of these observations are discussed in terms of their ability to contribute to a satellite-based lightning monitoring mission.

Number of lightning discharges causing damage to lightning arrester cables for aerial transmission lines in power systems  

SciTech Connect

Damage by lightning discharges to lightning arrester cables for 110-175 kV aerial transmission lines is analyzed using data from power systems on incidents with aerial transmission lines over a ten year operating period (1997-2006). It is found that failures of lightning arrester cables occur when a tensile force acts on a cable heated to the melting point by a lightning current. The lightning currents required to heat a cable to this extent are greater for larger cable cross sections. The probability that a lightning discharge will develop decreases as the amplitude of the lightning current increases, which greatly reduces the number of lightning discharges which damage TK-70 cables compared to TK-50 cables. In order to increase the reliability of lightning arrester cables for 110 kV aerial transmission lines, TK-70 cables should be used in place of TK-50 cables. The number of lightning discharges per year which damage lightning arrester cables is lowered when the density of aerial transmission lines is reduced within the territory of electrical power systems. An approximate relationship between these two parameters is obtained.

Low-level convergence and its role in convective intensity and frequency over the Houston lightning and rainfall anomaly  

E-Print Network (OSTI)

An increase in the amount of lightning and rainfall over the Houston area, compared to the surrounding rural areas, has been well documented in previous studies. The placement of a Shared Mobile Atmospheric Research and Teaching Radar (SMART-R) in the Houston area during the summer season of 2005 presented a unique opportunity to investigate the role of boundary-layer convergence in modulating convective frequency and intensity and, thereby, likely causing the rainfall and lightning anomalies. The role of the urban heat island (UHI) and the sea-breeze, as a source of low-level convergence leading to enhanced convection over Houston, was examined. Hourly average dual-Doppler wind and convergence maps were created on 1 X 1 km grids for an eleven-week period. By using these images along with average lightning, rainfall, and reflectivity for a large Houston-centered domain, it was possible to discern a correlation between low-level convergence and convection. Also, past findings of enhancement in lightning and rainfall over Houston and downwind of Houston were validated. High convergence levels for the Houston area in the mid-morning were followed closely by a peak in convection in the early afternoon. The enhancement of rainfall and lightning over and downwind of downtown was found to be primarily from a large increase in frequency of deep convective events when compared to the surrounding domain. Also, it was found that UHI, rather than sea-breeze, was likely the primary causative mechanism in the development of convection over the Houston area because of the lack of deep convection in areas equally affected by the sea-breeze and the timing of the convection compared to time of peak sea-breeze. An area of weaker enhancement south of Houston, not discussed in previous studies, was found to be present, possibly from the interactions between the bay-breeze off of the Galveston Bay and the seabreeze.

Electromagnetic field radiation model for lightning strokes to tall structures  

SciTech Connect

This paper describes observation and analysis of electromagnetic field radiation from lightning strokes to tall structures. Electromagnetic field waveforms and current waveforms of lightning strokes to the CN Tower have been simultaneously measured since 1991. A new calculation model of electromagnetic field radiation is proposed. The proposed model consists of the lightning current propagation and distribution model and the electromagnetic field radiation model. Electromagnetic fields calculated by the proposed model, based on the observed lightning current at the CN Tower, agree well with the observed fields at 2km north of the tower.

Lightning Activities in the DOE-EPRI Turbine Verification Program  

DOE Green Energy (OSTI)

The US Department of Energy (DOE)-Electric Power Research Institute (EPRI) Turbine Verification Program (TVP) has played a vital role in improving the understanding of lightning protection for wind turbines. In response to concerns from host utilities, the TVP began a lightning protection project to study the impact of lightning activity at the 6.0-megawatt (MW) wind power facility in Ft. Davis, Texas. McNiff Light Industry (MLI) and Global Energy Concepts (GEC) established a broad observation and documentation effort to survey the lightning protection methodologies used and to evaluate the damage resulting from lightning activity at the turbines. The 6.05-MW wind power plant in Searsburg, Vermont, was inspected after a severe lightning storm caused damage to several turbines there. Zond, McNiff, and consultants from Lightning Technologies, Inc. conducted post-damage inspections at both sites to develop recommendations for improving lightning protection. Site operators implemented the recommended mitigation strategies, and the turbines were monitored to determine if the protection measures improved project operations. This paper summarizes the experience gained through TVP's lightning-related research, and provides a set of guidelines for wind turbine manufacturers, owners, and operators.

A genetic algorithm based method for docking flexible molecules  

SciTech Connect

The authors describe a computational method for docking flexible molecules into protein binding sites. The method uses a genetic algorithm (GA) to search the combined conformation/orientation space of the molecule to find low energy conformation. Several techniques are described that increase the efficiency of the basic search method. These include the use of several interacting GA subpopulations or niches; the use of a growing algorithm that initially docks only a small part of the molecule; and the use of gradient minimization during the search. To illustrate the method, they dock Cbz-GlyP-Leu-Leu (ZGLL) into thermolysin. This system was chosen because a well refined crystal structure is available and because another docking method had previously been tested on this system. Their method is able to find conformations that lie physically close to and in some cases lower in energy than the crystal conformation in reasonable periods of time on readily available hardware.

A monthly climatological study of cloud-to-ground lightning characteristics throughout the contiguous United States: 1989-1994  

E-Print Network (OSTI)

The National Lightning Detection Network (NLDN) has been in operation since 1989. The NLDN is currently composed of a mixture of magnetic direction finders (DFs) and time-of-arrival (TOA) sensors which locate cloud-to-ground (CG) flashes as well as measure their polarity, peak current, and multiplicity. A monthly climatology for the contiguous United States was created for the six years of data to establish an "average year". Analysis was completed for the mean values and interannual variability of several lightning parameters: ground flash density, positive ground flash density, percentage positive lightning, multiplicity, and median first-stroke peak currents. In addition to these lightning characteristics, correlation between monthly lightning and precipitation was analyzed in different areas throughout the country. The 1989-1994 mean monthly maximum values were analyzed. Maximum monthly ground flash density values ranged from 0.050 km-2 in December along the southern Mississippi Valley to 2.96 km-2 in July in central Florida. Similarly, positive ground flash density values ranged from 0.0068 km-2 in December in eastern Texas to 0.12 km-2 in July in northern Kansas. In the percentage positive lightning field a persistent protrusion, with locally higher values, appeared from Minnesota southwestward into Colorado from April through August. Mean monthly percentage positive lightning was highest in December at 16.0% and lowest in August at 3.0%. The mean monthly negative multiplicity ranged from 2.32 in February to 2.78 in June. The mean monthly positive multiplicity ranged from 1.26 in December to 1.35 in July. Geographically, the monthly maxima for the negative multiplicity field were generally found along the Gulf Coastal states, especially in Florida during the summer months. Unlike the negative flashes, the monthly maxima for the positive flashes were generally found in the Midwest. The monthly positive median first-stroke peak current ranged from 39 kA in July-September to 66 kA in December and January. Values for negative flashes ranged from 29 kA in May and June to 43 kA in January. Finally, the correlation between monthly precipitation and lightning flash count was much greater (r 2 >0.6) in the central Great Plains than in the Pacific Northwest and Deep South (r 2 <0.11).

Lightning-induced coupling of the radiation belts to geomagnetically conjugate ionospheric regions  

SciTech Connect

Very low frequency (VLF) radio observations in Antarctica and North America provide the first evidence that bursts of energetic electrons from the earth's radiation belts commonly precipitate into geomagnetically conjugate ionospheric regions in response to lightning. The electrons, with energies ranging from tens of keV to over one MeV, appear to be scattered out of their otherwise stable trap in the earth's magnetic field by magnetospheric interactions with a regularly observed class of transient, lightning-generated VLF radio waves known as ducted whistlers. The precipitating electrons ionize atmospheric molecules at altitudes between 40 and 90 km, creating transient enhancements of ionization levels in conjugate locations. These ionospheric disturbances can be detected by their characteristic perturbations, sometimes called 'Trimpi events,' of the amplitude and phase of VLF transmitter signals propagating subionospherically within 200 to 250 km of the disturbed areas. The first detailed, one-to-one comparison of such signal perturbations, monitored in conjugate regions, with the multipath structure, arrival azimuths, and predicted electron scattering of simultaneously observed ducted whistlers suggests that every ducted whistler precipitates bursts of radiation belt electrons. If so, the estimated rate at which ducted whistlers contribute to radiation belt losses is comparable to that predicted for plasmaspheric hiss, a different class of magnetospheric wave that is often considered to control the structure of the belts. Lightning could therefore play a significant role in the maintenance of radiation belt equilibrium.

Transient performance of substation grounding systems subjected to lightning and similar surge currents  

SciTech Connect

The frequency and time domain performance of a typical substation grounding system subjected to a lightning strike is described and discussed. The computed scalar potentials, electric fields and magnetic fields are presented graphically as a function of spatial coordinate, as a function of time and as a function of both. It is believed that these detailed results have not been published before. First, a double exponential lightning surge current is injected into the center of a square ground grid. This same surge current is then injected at one corner of the grid. The response of the grounding system to the frequency domain electromagnetic spectrum of this signal is computed by a frequency domain electromagnetic field analysis software package. Once all the frequency responses have been computed, the temporal and spatial distributions of the electromagnetic fields inside and near the substation are obtained by an inverse Fourier transformation of all these responses. The results are compared with some well known low frequency results and to recent published work in this area. These results indicate that the performance of the grounding system is significantly dependent on frequency and on the point of impact of the lightning strike.

Lightning and radar observations of hurricane Rita landfall  

SciTech Connect

Los Alamos National Laboratory (LANL) owns and operates an array of Very-Low Frequency (VLF) sensors that measure the Radio-Frequency (RF) waveforms emitted by Cloud-to-Ground (CG) and InCloud (IC) lightning. This array, the Los Alamos Sferic Array (LASA), has approximately 15 sensors concentrated in the Great Plains and Florida, which detect electric field changes in a bandwidth from 200 Hz to 500 kHz (Smith et al., 2002). Recently, LANL has begun development of a new dual-band RF sensor array that includes the Very-High Frequency (VHF) band as well as the VLF. Whereas VLF lightning emissions can be used to deduce physical parameters such as lightning type and peak current, VHF emissions can be used to perform precise 3d mapping of individual radiation sources, which can number in the thousands for a typical CG flash. These new dual-band sensors will be used to monitor lightning activity in hurricanes in an effort to better predict intensification cycles. Although the new LANL dual-band array is not yet operational, we have begun initial work utilizing both VLF and VHF lightning data to monitor hurricane evolution. In this paper, we present the temporal evolution of Rita's landfall using VLF and VHF lightning data, and also WSR-88D radar. At landfall, Rita's northern eyewall experienced strong updrafts and significant lightning activity that appear to mark a transition between oceanic hurricane dynamics and continental thunderstorm dynamics. In section 2, we give a brief overview of Hurricane Rita, including its development as a hurricane and its lightning history. In the following section, we present WSR-88D data of Rita's landfall, including reflectivity images and temporal variation. In section 4, we present both VHF and VLF lightning data, overplotted on radar reflectivity images. Finally, we discuss our observations, including a comparison to previous studies and a brief conclusion.

Evolution of vertical drafts and cloud-to-ground lightning within the convective region of a mesoscale convective complex  

E-Print Network (OSTI)

The evolution of the area-averaged vertical velocity within the objectively defined convective region of the 4 June 1985 PRE-STORM (Preliminary Regional Experiment for Stormscale Operational and Research Meteorology-Central Phase) mesoscale convective complex (MCC) was examined over a 100 minute period during the storm's mature stage and compared to that of a squall line. The area-averaged vertical velocity profiles from twenty dual-Doppler analyses indicated significant differences in convective intensity both spatially and temporally. The peak magnitudes of the mid-to-upper level area-averaged vertical velocity were initially comparable to those from a squall line but became much weaker. The distribution of vertical velocities at mid-to-upper levels was consistent with weakening convection as the percentage of weak updrafts and downdrafts grew at the expense of stronger vertical motions. Typically the non-squall MCC had a much larger percentage of strong downdrafts than did the squall line. Horizontal and vertical cross-sections of both vertical velocity and reflectivity confirmed that the MCC was evolving toward a state with fewer and less intense updraft cores while cross-sections of storm relative flow revealed a descending rear-to-front inflow at later analysis times which reached the surface near locations of active convection. The relationship of cloud-to-ground (CG) lightning to the kinematic structure of the MCC was also studied. For mesoscale regions there was a 10-20 minute time lag between the peak convective intensity and the peak CG flash rate. A similar delay was found on the convective scale for some convective cells, however, other apparently similar cells had little CG lightning throughout their evolution. An analysis of the vertical profiles of the vertical velocity, reflectivity and their gradients above CG lightning suggested a preferred vertical structure of these fields for CG lightning. CG lightning occurred beneath greater than average vertical velocities at mid-to-upper levels and greater than average vertical velocity gradients and reflectivity at all levels. CG lightning also occurred beneath greater than average reflectivity gradients at mid and upper-levels but beneath smaller than average reflectivity gradients at low-levels due to its avoidance of the highest reflectivity gradient regions.

Global lightning and severe storm monitoring from GPS orbit  

Science Conference Proceedings (OSTI)

Over the last few decades, there has been a growing interest to develop and deploy an automated and continuously operating satellite-based global lightning mapper [e.g. Christian et al., 1989; Weber et al., 1998; Suszcynsky et al., 2000]. Lightning is a direct consequence of the electrification and breakdown processes that take place during the convective stages of thunderstorm development. Satellite-based lightning mappers are designed to exploit this relationship by using lightning detection as a proxy for remotely identifying, locating and characterizing strong convective activity on a global basis. Global lightning and convection mapping promises to provide users with (1) an enhanced global severe weather monitoring and early warning capability [e.g. Weber et al., 1998] (2) improved ability to optimize aviation flight paths around convective cells, particularly over oceanic and remote regions that are not sufficiently serviced by existing weather radar [e.g. Weber et al., 1998], and (3) access to regional and global proxy data sets that can be used for scientific studies and as input into meteorological forecast and global climatology models. The physical foundation for satellite-based remote sensing of convection by way of lightning detection is provided by the basic interplay between the electrical and convective states of a thundercloud. It is widely believed that convection is a driving mechanism behind the hydrometeor charging and transport that produces charge separation and lightning discharges within thunderclouds [e.g. see chapter 3 in MacGorman and Rust, 1998]. Although cloud electrification and discharge processes are a complex function of the convective dynamics and microphysics of the cloud, the fundamental relationship between convection and electrification is easy to observe. For example, studies have shown that the strength of the convective process within a thundercell can be loosely parameterized (with large variance) by the intensity of the electrical activity within that cell as measured by the lightning flash rate. Williams [2001] has provided a review of experimental work that shows correlations between the total lightning flash rate and the fifth power of the radar cloud-top height (i.e. convective strength) of individual thunder cells. More recently, Ushio et al., [2001] used a large statistical sampling of optical data from the Lightning Imaging Sensor (LIS) in conjunction with data provided by the Precipitation Radar (PR) aboard the Tropical Rainfall Monitoring Mission (TRMM) satellite to conclude that the total lightning flash rate increases exponentially with storm height. Lightning activity levels have also been correlated to cloud ice content, a basic product of the convective process. For example, Blyth et al. [2001] used the Thermal Microwave Imager (TMI) aboard the TRMM satellite to observe a decrease in the 37 and 85 GHz brightness temperatures of upwelling terrestrial radiation during increased lightning activity. This reduction in brightness temperature is believed to be the result of increased ice scattering in the mixed phase region of the cloud. Toracinta and Zipser [2001] have found similar relationships using the Optical Transient Detector (OTD) satellite instrument and the Special Sensor Microwave Imager (SSM/I) aboard the DMSP satellites.

Total lightning observations of severe convection over North Texas  

E-Print Network (OSTI)

Five severe convective cells over North Texas from three separate dates were examined to determine what three dimensional, or total lightning data can add to the understanding of a convective cells intensity, propagation, and severe weather potential. Total lightning data were obtained from Vaisala Inc.s Dallas/Fort Worth (D/FW) Lightning Detection and Ranging (LDAR) network. Radar data from two Weather Surveillance Radar 1988 Doppler (WSR-88D) sites were used for position data and information regarding the intensity and kinematic properties of each cell. Total lightning products used by the National Weather Service Forecast Office in Fort Worth, Texas were compared to total lightning flash rate; a quantity that has been shown to be correlated to changes in cell intensity inferred from other sources, such as radar and satellite data. These products, specifically flash extent density (FED) were also compared to CG flash rate and radar derived measures from the WSR-88D sites. The results of this work show that FED and total flash rate are well correlated, with an average Pearson correlation value of 0.73, indicating that previous total flash rate results may also apply to FED. Lightning hooks, holes, and notches in FED displays indicated likely updraft regions, while appendages were observed to develop prior to deviant motion with two supercells. These results, combined with a greater update frequency provided a useful complement to radar data in the warning decision process. FED jumps were observed prior to several severe weather reports, indicating that total lightning activity may be related to updraft strength as found in past studies. However, FED jumps were sometimes observed without any associated severe event. More work is clearly needed to define what FED changes are of most importance in the short-term prediction of storm severity. The usefulness of the total lightning data on these dates was dependant upon LDAR network status and distance of the cell from the network center. The results of this study suggest that combining total flash rate trends with visual displays of FED provides the greatest added benefit to forecasters in maintaining situational awareness during warning operations.

Lightning, fire and longleaf pine: Using natural disturbance to guide management.  

Science Conference Proceedings (OSTI)

Abstract The importance of lightning as an ignition source for the fire adapted longleaf pine (Pinus palustris) ecosystem is widely recognized. Lightning also impacts this system on a smaller scale by causing individual tree mortality. The objective of this study was to determine mortality due to lightning and other agents in longleaf stands on the Ocala National Forest in central Florida and to quantify lightning ignited fire. Mortality from lightning was also tracked in longleaf stands on the Savannah River Site in South Carolina. Lightning killed more trees than any other agent with a mean mortality of nearly 1 tree/3 ha/yr in Florida and 1 tree/8 ha/yr in South Carolina. The probability of a tree being struck by lightning increased as a function of tree height at both sites, i.e. lightning preferentially removed the largest trees from the stand. In addition lightning strikes were clumped within stands, sometimes killed multiple trees with a single strike, and often hit trees on the edge of existing gaps. The combination of these processes means gaps suitable for regeneration within longleaf stands are created quite rapidly. This information provides guidelines for the development of selection harvest systems based on this natural disturbance. Although lightning activity was greatest during the summer months in Florida and most fires occurred in June, the probability of a strike causing a fire was highest in February to May.

Waste Isolation Pilot Plant TruDock crane system analysis  

SciTech Connect

The WIPP TruDock crane system located in the Waste Handling Building was identified in the WIPP Safety Analysis Report (SAR), November 1995, as a potential accident concern due to failures which could result in a dropped load. The objective of this analysis is to evaluate the frequency of failure of the TruDock crane system resulting in a dropped load and subsequent loss of primary containment, i.e. drum failure. The frequency of dropped loads was estimated to be 9.81E-03/year or approximately one every 102 years (or, for the 25% contingency, 7.36E-03/year or approximately one every 136 years). The dominant accident contributor was the failure of the cable/hook assemblies, based on failure data obtained from NUREG-0612, as analyzed by PLG, Inc. The WIPP crane system undergoes a rigorous test and maintenance program, crane operation is discontinued following any abnormality, and the crane operator and load spotter are required to be trained in safe crane operation, therefore it is felt that the WIPP crane performance will exceed the data presented in NUREG-0612 and the estimated failure frequency is felt to be conservative.

Thunderstorm characteristics of cloud-to-ground lightning at the Kennedy Space Center, Florida: a study of lightning initiation signatures as indicated by Doppler radar  

E-Print Network (OSTI)

A sum-nary of lightning characteristics was developed for the NASA Kennedy Space Center (KSC). From-n a 1989-1996 data set, the spatial patterns, temporal patterns, and first stroke mean peak current were analyzed. Forty five thunderstorms were chosen due to their isolated development over KSC. Forty of the storms representing summer (May through September) airmass thunderstorms and five storms representing winter were examined for their storms-n initiation characteristics. Radar reflectivity echoes at the -10 C,-15 C, and-20 C temperature heights were associated with cloud-to-ground (CG) lightning strike locations from the National Lightning Detection Network. A distinct region of high ground flash densities can be seen over land matching the topography of the KSC coastline. A maximum of values was observed during the summer months for both negative and positive flashes. The absolute i-magnitude of negative peak currents was found to be higher than positive peak currents in Florida. Although thunderstorms can Occur at any time during the day, the diurnal distribution of lightning flashes showed that the afternoon (2000-2200 UTC) was the time of maximum lightning activity. From a time history of radar-echoes, it was found that the 30 dBZ echo detected at the-I 5'C temperature height is the best indicator of the beginning of CG lightning activity. The observed median lag time between this lightning initiation signature and the beginning of CG lightning flashes was 15.5 minutes. Other lightning initiation signatures were also examined at all three temperature heights and did not yield as successful results.

Cloud-to-ground lightning-precipitation relationships in the South Central United States  

E-Print Network (OSTI)

Despite the general coexistence of cloud-to-ground (CG) lightning and precipitation, there have been few studies on the nature of the relationship between these two phenomena. This study endeavors to explore this relationship, concentrating on three facets: the strength and variability of the linear correlation between the two parameters, and the possible benefits of including additional parameters to this relationship; the differences in several atmospheric and lightning parameters corresponding to differences in the precipitation-to-CG lightning ratio, and the search for an optimal radius for inclusion of CG lightning flashes when comparing them to point precipitation values. Six regions (each on the order of I' latitude by I' longitude) from the states of Nebraska, Kansas, Oklahoma, Texas, and Louisiana are examined. The parameters are examined on daily and/or monthly time scales. This study uses CG lightning data which were recorded by the National Lightning Detection Network (NLDN) during the months of April through October in the years 1989 to 1993. Precipitation data are included from all available first-order, second-order, and cooperative stations. Atmospheric parameters are computed from soundings in the region. A primary tool used in the analyses is the linear regression model for examining linear relations among CG lightning, precipitation, and other parameters. In addition, the t-test and Wilcoxon Rank Sum test are used to discern statistically significant differences in atmospheric and lightning parameters between groups of days categorized by the precipitation-to-CG lightning ratio. The results show that linear correlations between CG lightning and precipitation for a region are highly varied; there are generally higher correlations in regions further away from the Gulf of Mexico. The only parameter which is a significantly beneficial addition to the model which included CG lightning and precipitation is a measure of the amount of positive CG flashes. When days are categorized by a precipitation-to-CG lightning ratio, the percent positive shows the most dramatic differences, with values on "high precipitation-to-lightning" days from roughly five to twelve times the value on "low precipitation-to-lightning" days. Several other parameters show statistically significant differences as well. Lastly, tests on several different radii suggest that there is no consistent optimal radius for CG lightning-precipitation comparisons.

Lightning, atmospheric electricity and climate change  

SciTech Connect

Temperature records indicate that a global warming of 0.5{minus}0.7{degrees}C has occurred over the past century (Hansen and Lebedeff, 1987). Whether this trend is a result of increased trace gas concentrations in the atmosphere, or simply a result of natural variability; is still not known. These temperature trends are derived from thousands of observations worldwide. However, these observations are concentrated largely over continental areas, and then mainly in the northern hemisphere`s populated regions. This northern hemisphere continental bias results in large uncertainties in estimates of global temperature trends. Due to the increasing evidence that the present buildup of greenhouse gases in the atmosphere may result in an additional global warming of 1-5{degrees}C by the year 2050 (IPCC, 1990), it is increasingly important to find afternative methods to monitor fluctuations in global surface temperatures. As shown by two recent studies (Williams, 1992; Price, 1993), the global atmospheric electric circuit may provide a promising afternative for monitoring future climate change.

An examination of the relationship between cool season tornadoes and cloud-to-ground lightning flashes  

E-Print Network (OSTI)

The southeast United States is prone to severe weather throughout the year. Despite technological advances, some severe weather events occasionally remain unwarned in this part of the country. Past studies examined the relationship between cloud-to-ground (CG) lightning and warm season severe weather episodes. The present study examined the relationship between cool season tornadoes and CG lightning, with a focus over the southeastern United States, where most cool season tornadoes occur. Data from the Storm Prediction Center and National Lightning Detection Network (NLDN) were used to investigate CG lightning properties within 50 km and one hour before tornado touchdown. This was completed over a period of 13 cool seasons from October 1989 through March 2002. Of 3325 tornado events, 2358 contained at least one NLDN-detectable flash. CG lightning attributes of peak current, multiplicity, and flash density compared well with those of prior warm season lightning research. Overall event frequency appeared to be lower than in the warm season. Almost all Central Plains events were accompanied by at least one NLDN-detectable flash. Up to 70% of tornado events near the Gulf of Mexico and Atlantic coasts contained no NLDN-detectable lightning. Although it is not known why this trend was observed, it is speculated that NLDN detection efficiency and/or storm structure differences may play a role in these observations. Warm season studies have correlated tornadoes with predominantly positive (>50% positive CG lightning), or PPCG storms. Gridded maps showed the greatest percentage and highest frequency of cool season PPCG storms across Kansas and Nebraska, with up to 70% of events associated with PPCG lightning. A secondary, albeit lower, frequency maximum extended 1?° to 2?° inland across Louisiana into North Carolina. This study also subjectively defined a storm with â??enhancedâ? positive cloud-to-ground (EPCG) lightning as one containing >25% positive cloud-to-ground lightning, which corresponds to approximately the 75th percentile of all cool season tornadoes. This has lead to speculation that EPCG criterion may be a better indicator of the possibility of severe weather than the traditional PPCG criterion.

Gamma-ray bursts and other sources of giant lightning discharges in protoplanetary systems  

E-Print Network (OSTI)

Lightning in the solar nebula is considered to be one of the probable sources for producing the chondrules that are found in meteorites. Gamma-ray bursts (GRBs) provide a large flux of gamma-rays that Compton scatter and create a charge separation in the gas because the electrons are displaced from the positive ions. The electric field easily exceeds the breakdown value of ~1 V m^-1 over distances of order 0.1 AU. The energy in a giant lightning discharge exceeds a terrestrial lightning flash by a factor of ~10^12. The predicted post-burst emission of gamma-rays from accretion into the newly formed black hole or spin-down of the magnetar is sufficiently intense to cause a lightning storm in the nebula that lasts for days and is more probable than the GRB because the radiation is beamed into a larger solid angle. The giant outbursts from nearby soft gamma-ray repeater sources (SGRs) are also capable of causing giant lightning discharges. The total amount of chondrules produced is in reasonable agreement with the observations of meteorites. Furthermore in the case of GRBs most chondrules were produced in a few major melting events by nearby GRBs and lightning occurred at effectively the same time over the whole nebula, and provide accurate time markers to the formation of chondrules and evolution of the solar nebula. This model provides a reasonable explanation for the delay between the formation of calcium aluminium inclusions (CAIs) and chondrules.

Annual Report: 2010-2011 Storm Season Sampling For NON-DRY DOCK STORMWATER MONITORING FOR PUGET SOUND NAVAL SHIPYARD, BREMERTON, WA  

SciTech Connect

This interim report summarizes the stormwater monitoring conducted for non-dry dock outfalls in both the confined industrial area and the residential areas of Naval Base Kitsap within the Puget Sound Naval Shipyard (referred to as the Shipyard). This includes the collection, analyses, and descriptive statistics for stormwater sampling conducted from November 2010 through April 2011. Seven stormwater basins within the Shipyard were sampled during at least three storm events to characterize non-dry dock stormwater discharges at selected stormwater drains located within the facility. This serves as the Phase I component of the project and Phase II is planned for the 2011-2012 storm season. These data will assist the Navy, USEPA, Ecology and other stakeholders in understanding the nature and condition of stormwater discharges from the Shipyard and inform the permitting process for new outfall discharges. The data from Phase I was compiled with current stormwater data available from the Shipyard, Sinclair/Dyes Inlet watershed, and Puget Sound in order to support technical investigations for the Draft NPDES permit. The permit would require storm event sampling at selected stormwater drains located within the Shipyard. However, the data must be considered on multiple scales to truly understand potential impairments to beneficial uses within Sinclair and Dyes Inlets.

The warning time for cloud-to-ground lightning in isolated, ordinary thunderstorms over Houston, Texas  

E-Print Network (OSTI)

Lightning detection over Houston, Texas is possible with the Lightning Detection and Ranging (LDAR-II) network and the National Lightning Detection Network (NLDN). A comparison of the two datasets in conjunction with 37 isolated, ordinary thunderstorms reveals a time separation of 3.1 minutes between the first detected Very High Frequency (VHF) source (i.e. first intracloud discharge) and the first cloud-toground (CG) lightning flash. This CG warning time is increased to 16.1 minutes when using the radar-defined criterion of when the 30-dBZ contour first reaches the -10C isotherm level. Several attempts were made to establish a similar characteristic that could be used to forewarn the occurrence of the final CG in this storm type. Based on the average radar characteristics during the last CG flash in each thunderstorm case, CG activity comes to an end when the 45-dBZ echo falls below the -10C isotherm. Detection efficiencies that remain slightly less than perfect for each network may have allowed for some error when analyzing VHF sources and ground flashes for each convective case. Exhibiting this possible error, four cases actually recorded a greater number of CG flashes than intracloud flashes, which is contrary to typical lightning characteristics. Future studies hope to increase the number of thunderstorm cases to analyze as the LDAR network continues to observe more lightning events. Also, similar approaches could be implemented in differing geographic regions of the country to observe if these lightning characteristics vary depending on latitude, longitude, or climate.

Thunderstorm lightning and radar characteristics: insights on electrification and severe weather forecasting  

E-Print Network (OSTI)

Total lightning mapping, along with radar and NLDN cloud-to-ground lightning data, can be used to diagnose the severity of a storm. Analysis of the 13 October 2001 supercell event (Dallas-Fort Worth, Texas), some supercells of which were tornadic, shows that LDAR II lightning source heights (quartile, median, and 95th percentile heights) increased as the storms intensified. Most of the total lightning occurred where reflectivity cores extended upwards and within regions of reflectivity gradient rather than in reflectivity cores. A total lightning hole was associated with an intense, nontornadic supercell on 6 April 2003. This feature was nonexistent from all supercells analyzed during the 13 October case. During tornadogenesis, the radar and LDAR II data indicated updraft weakening. The height of the 30 dBZ radar top began to descend approximately 10 minutes (2 volume scans) before tornado touchdown in one storm. Total lightning and CG flash rates decreased by up to a factor of 5 to a minimum during an F2 tornado touchdown associated with this storm. LDAR II source heights all showed descent by 2-4 km during a 25 minute period prior to and during this tornado touchdown. This drastic trend of decreasing source heights was observed in two tornadic storms prior to and during tornado touchdown, but did not occur in non-tornadic supercells, suggesting that these parameters can be useful to forecasters. These observations agree with tornadogenesis theory that an updraft weakens and the mesocyclone can become divided (composed of both updraft and downdraft) when a storm becomes tornadic. LDAR II source density contours were comma-shaped in association with severe wind events within mesoscale convective systems (MCSs) on 13 October 2001 and 27 May 2002. This signature is similar to the radar reflectivity bow echo. Consistent relationships between severe weather, radar and lightning storm characteristics (i.e., lightning heights) were not found for cells within MCSs as was the case for supercells. Cell interactions within MCSs are believed to weaken these relationships as reflectivity and lightning from nearby storms contaminate the cells of interest. It is also more difficult to clearly define a cell within an MCS.

Coupling measurement and lightning threat assessment report for Pantex Cell 12-44-1  

SciTech Connect

This report is the first of a series that will quantify the lightning threat to the Pantex Plant where high-risk operations occur. More information can be found in the report written by the Lightning Protection Team [1] and Sandia National Laboratory documents. Low-power RF coupling measurements were completed on Cell 12-44-1 in May 1998. These measurements quantify the voltage and current levels that could leak into the cell from possible lightning strike points. Cell 1 is representative of the most ?leaky? class of cells at Pantex because the floor was not intentionally electrically connected to the walls. From the measurement data, linear models were developed. These transfer functions allow us to calculate the effect in the cell from the much higher power lightning threat. Two types of coupling paths were characterized: (1) external ventilation stack to cell interior and (2) cell ceiling to other cell elements. For the maximum lightning threat [2], an estimate of the maximum cell-to-floor voltage is 150 kV. The extrapolated voltage levels at normal working heights are lower. The potential between the air duct and the electro-static ground is estimated to be 4 kV. A secondary goal was to compare results with Sandia as a quality control check. While the estimated maximum ceiling-to-floor voltages are similar, the comparison was limited by high-frequency resonances on the drive wire.

Protection characteristics of a Faraday cage compromised by lightning burnthrough.  

SciTech Connect

A lightning flash consists of multiple, high-amplitude but short duration return strokes. Between the return strokes is a lower amplitude, continuing current which flows for longer duration. If the walls of a Faraday cage are made of thin enough metal, the continuing current can melt a hole through the metal in a process called burnthrough. A subsequent return stroke can couple energy through this newly-formed hole. This LDRD is a study of the protection provided by a Faraday cage when it has been compromised by burnthrough. We initially repeated some previous experiments and expanded on them in terms of scope and diagnostics to form a knowledge baseline of the coupling phenomena. We then used a combination of experiment, analysis and numerical modeling to study four coupling mechanisms: indirect electric field coupling, indirect magnetic field coupling, conduction through plasma and breakdown through the hole. We discovered voltages higher than those encountered in the previous set of experiments (on the order of several hundreds of volts).

A simple approach to improve lightning performance of an uprated substation  

Science Conference Proceedings (OSTI)

This paper presents a simple method to minimize lightning surges entering an uprated or compact substation. A severe lightning stress is caused by a backflashover in close proximity to the substation. Feasibility of uprating is based on the surge arrester technology available at present. However, some aspects of line design offer opportunities in reducing frequency and severity of lightning surges imposed on the substation. The tower surge response adds an inductive overshoot only during the front of the stroke which reduces considerably during the tail. If backflashover does not occur before reflections from adjacent towers arrive, it is unlikely to occur at all. Use of guys and underbuilt ground wires in the limiting distance will produce reflections with larger magnitude and reduce the effective surge impedance of the tower. This would not only reduce backflashover frequency but will also minimize crest and duration of surges entering the substation.

Lightning overvoltage protection of the paddock 362-145 kV Gas-Insulated Substation  

SciTech Connect

Backflashovers close to the Paddiock 362-145 kV Gas-Insulated Substation (GIS) have been analyzed with the Electro-Magnetic Transient Program (EMTP) using a frequency dependent multi-conductor system. The severity of the lightning stroke currents were derived based on recent recordings in the eastern United States. Impacts of corona attenuation and distortion were accounted for using a shunt linear model approach. Turn-up effects of both line insulator flashover voltages and surge arrester protective characteristics were represented based on manufacturer's volt-time curves. Wave shaping effects of substation capacitances (ie., PT's transformers, CCPD's) were also modeled. Results show the importance of various modeling details in determining the overvoltages inside the GIS due to close backflashovers, which are caused by lightning strokes with varying intensity. These results are aimed at better evaluation of lightning protection requirements for GIS protected by metal-oxide surge arresters.

Radar-Derived Forecasts of Cloud-to-Ground Lightning Over Houston, Texas  

E-Print Network (OSTI)

Ten years (1997 - 2006) of summer (June, July, August) daytime (14 - 00 Z) Weather Surveillance Radar - 1988 Doppler data for Houston, TX were examined to determine the best radar-derived lightning forecasting predictors. Convective cells were tracked using a modified version of the Storm Cell Identification and Tracking (SCIT) algorithm and then correlated to cloud-to-ground lightning data from the National Lightning Detection Network (NLDN). Combinations of three radar reflectivity values (30, 35, and 40 dBZ) at four isothermal levels (-10, -15, -20, and updraft -10 degrees C) and a new radar-derived product, vertically integrated ice (VII), were used to optimize a radar-based lightning forecast algorithm. Forecasts were also delineated by range and the number of times a cell was identified and tracked by the modified SCIT algorithm. This study objectively analyzed 65,399 unique cells, and 1,028,510 to find the best lightning forecast criteria. Results show that using 30 dBZ at the -20 degrees C isotherm on cells within 75 km of the radar that have been tracked for at least 2 consecutive scan produces the best forecasts with a critical success index (CSI) of 0.71. The best VII predictor was 0.734 kg m-2 on cells within 75 km of the radar that have been tracked for at least 2 consecutive scans producing a CSI of 0.68. Results of this study further suggest that combining the radar reflectivity and VII methods can result in a more accurate lightning forecast than either method alone.

Lightning arrestor connector lead magnesium niobate qualification pellet test procedures.  

SciTech Connect

Enhanced knowledge preservation for DOE DP technical component activities has recently received much attention. As part of this recent knowledge preservation effort, improved documentation of the sample preparation and electrical testing procedures for lead magnesium niobate--lead titanate (PMN/PT) qualification pellets was completed. The qualification pellets are fabricated from the same parent powders used to produce PMN/PT lightning arrestor connector (LAC) granules at HWF&T. In our report, the procedures for fired pellet surface preparation, electrode deposition, electrical testing and data recording are described. The dielectric measurements described in our report are an information only test. Technical reasons for selecting the electrode material, electrode size and geometry are presented. The electrical testing is based on measuring the dielectric constant and dissipation factor of the pellet during cooling from 280 C to 220 C. The most important data are the temperature for which the peak dielectric constant occurs (Curie Point temperature) and the peak dielectric constant magnitude. We determined that the peak dielectric constant for our procedure would be that measured at 1 kHz at the Curie Point. Both the peak dielectric constant and the Curie point parameters provide semi-quantitative information concerning the chemical and microstructural homogeneity of the parent material used for the production of PMN/PT granules for LACs. Finally, we have proposed flag limits for the dielectric data for the pellets. Specifically, if the temperature of the peak dielectric constant falls outside the range of 250 C {+-} 30 C we propose that a flag limit be imposed that will initiate communication between production agency and design agency personnel. If the peak dielectric constant measured falls outside the range 25,000 {+-} 10,000 we also propose that a flag limit be imposed.

Environmental control of cloud-to-ground lightning polarity in severe storms  

E-Print Network (OSTI)

In this study, it is hypothesized that the mesoscale environment can indirectly control the cloud-to-ground (CG) lightning polarity of severe storms by directly affecting their structural, dynamical, and microphysical properties, which in turn directly control cloud electrification and CG flash polarity. A more specific hypothesis, which has been supported by past observational and laboratory charging studies, suggests that broad, strong updrafts and associated large liquid water contents in severe storms lead to enhanced positive charging of graupel and hail via the noninductive charging mechanism, the generation of an inverted charge structure, and increased positive CG lightning production. The corollary is that environmental conditions favoring these kinematic and microphysical characteristics should support severe storms generating an anomalously high (> 25%) percentage of positive CG lightning (i.e., positive storms), while environmental conditions relatively less favorable should sustain storms characterized by a typical (? 25%) percentage of positive CG lightning (i.e., negative storms). Forty-eight inflow proximity soundings were analyzed to characterize the environments of nine distinct mesoscale regions of severe storms (four positive and five negative) on six days during May June 2002 over the central United States. This analysis clearly demonstrated significant and systematic differences in the mesoscale environments of positive and negative storms, which were consistent with the stated hypothesis. When compared to negative storms, positive storms occurred in environments associated with a drier low to midtroposphere, higher cloud base height, smaller warm cloud depth, stronger conditional instability, larger 0-3 km AGL wind shear, stronger 0-2 km AGL storm-relative wind speed, and larger buoyancy in the mixed-phase zone, at a statistically significant level. Differences in the warm cloud depth of positive and negative storms were by far the most dramatic, suggesting an important role for this parameter in controlling CG lightning polarity. Subjective visual inspection of radar imagery revealed no strong relationship between convective mode and CG lightning polarity, and also illustrated that positive and negative severe storms can be equally intense.

VLF and LF signatures of mesospheric/lower ionospheric response to lightning discharges  

SciTech Connect

New evidence is presented of disturbances of the electrical conductivity of the nighttime mesosphere and the lower ionosphere in association with lightning discharges. In addition to extensive documentation of the characteristics of a class of event heretofore referred to as early/fast VLF events [Inan et al.], this data reveal a new feature of these events, consisting of a postonset peak that typically lasts for 1-2 s. The authors also report the observation of short-duration VLF or LF perturbation, in which the amplitude of the subionospheric signal exhibits a sudden change within 20 ms of the causative lightning discharge, and recovers back to its original level in < 3 s. These short-duration events have characteristics similiar to the previously observed rapid onset, rapid decay VLF signatures [Dowden et al.]. Both the typical and rapidly recovering events are observed primarily when the causative lightning discharge is within {+-}50 km of the VLF or LF great circle propagation path, indicating that the scattering from the localized disturbance is highly collimated in the forward direction. The latter in turn implies that for the parameters in hand, the transverse extent of the disturbance must be at least {approximately} 100-150 km. The measured VLF signatures are compared with the predictions of a three-dimensional model of subionospheric VLF propogation and scattering in the presence of localized ionospheric disturbances produced by electromagnetic impulses and quasi-electrostatic (QE) fields produced by lightning discharges. The rapidly recovering or short-duration events are consistent with the heating of the ambient electrons by quasi-static electric fields, in cases when heating is not intense enough to exceed the attachment or ionization thresholds. When no significant electron density changes occur, the conductivity changes due to heating alone last only as long as the QE fields, typically less than a few seconds. 29 refs., 12 figs.

A Ball Lightning Model as a Possible Explanation of Recently Reported Cavity Lights  

SciTech Connect

The salient features of cavity lights, in particular, mobile luminous objects (MLO's), as have been experimentally observed in superconducting accelerator cavities, are summarized. A model based upon standard electromagnetic interactions between a small particle and the 1.5 GHz cavity excitation field is described. This model can explain some features of these data, in particular, the existence of particle orbits without wall contact. While this result is an important success for the model, it is detailed why the model as it stands is incomplete. It is argued that no avenues for a suitable extension of the model through established physics appear evident, which motivates an investigation of a model based upon a more exotic object, ball lightning. As discussed, further motivation derives from the fact that there are significant similarities in many of the qualitative features of ball lightning and MLO's, even though they appear in quite different circumstances and differ in scale by orders of magnitude. The ball lightning model, which incorporates electromagnetic charges and currents, is based on a symmetrized set of Maxwell's equations in which the electromagnetic sources and fields are characterized by a process called dyality rotation. It is shown that a consistent mathematical description of dyality rotation as a physical process can be achieved by adding suitable (phenomenological) current terms to supplement the usual current terms in the symmetrized Maxwell's equations. These currents, which enable the conservation of electric and magnetic charge, are called vacuum currents. It is shown that the proposed ball lightning model offers a good qualitative explanation of the perplexing aspects of the MLO data. Avenues for further study are indicated.

Evaluation of the electromagnetic effects due to direct lighting to nuclear explosive areas at Pantex. Final report  

Science Conference Proceedings (OSTI)

This report summarizes the effort to quantify the electromagnetic environments in the nuclear explosive areas at Pantex due to direct lightning. The fundamental measure of the threat to nuclear safety is assumed to be the maximum voltage between any two points in an assembly area, which is then available for producing arcing or for driving current into critical subsystems of a nuclear weapon. This maximum voltage has been computed with simple analytical models and with three-dimensional finite-difference computer codes.

A classification of Texas thunderstorms according to their cloud-to-ground lightning characteristics during spring 1993  

E-Print Network (OSTI)

The National Lightning Detection Network detected more than 800 000 cloud-to-ground lightning flashes from 119 storm systems which affected Texas during April-June 1993. This study attempted to characterize these flashes over the entire three-month period, then classify the storms according to their lightning characteristics, relative to their type, geographical location, and maximum echo height. Examination of the flashes over the entire period found that the highest ground flash densities within the study region (26.50-34.5" N, 102'-930 W) were in southeastern Texas. The flashes lowering negative charge to ground had a mean multiplicity of 2.91 strokes and median first-return stroke peak current of 32.1 kiloamperes (kA). Six percent of the flashes were positive; the positive flashes exhibited a mean multiplicity of 1.43 and a median peak current of 36.6 kA. Relating the data to storm type revealed that frontal storm lightning was 2-3 times more positive than observed in airmass storms. Negative lightning in airmass storms had slightly higher mean multiplicities and peak currents than in frontal storms, while frontal storms had higher positive flash multiplicities and peak current values. Analysis by storm location showed that inland storm lightning flashes were more than twice as positive as those in coastal storms, but coastal storms had lower multiplicities and higher peak currents (both polarities) than observed in inland storms. Comparison of lightning characteristics to maximum echo height found a positive correlation between flash rates and echo heights, a negative correlation between percent positive rates and echo heights, a positive correlation between negative flash multiplicities and echo heights, and a negative correlation between positive Flash peak currents and echo heights. Negative flash peak currents remained relatively constant with increasing echo heights.

Radar, satellite, and lightning characteristics of select mesoscale convective systems in Texas  

E-Print Network (OSTI)

This study compares radar data from the League City, Texas WSR-88D and cloud-to-ground (CG) lightning data for a set of eight mesoscale convective systems (MCSs) which occur at various stages of development along the upper Texas Gulf Coast. Vertical profiles of radar reflectivity (VPRR) as well as plan views and vertical cross sections are constructed to characterize the structure and relative strength of each MCS. The VPRR are also compared with similar profiles from tropical oceanic MCSs. The data show that in all cases the majority of negative CG lightning flashes are located near high reflectivity convective cores (> 35 dBZ) in the mixed phase region (O'C -20'C). Growing or mature MCSs typically had larger negative flash counts and higher percentages of negative lightning (> 80%) associated with convective cores than MCSs at later stages of their life cycle. Comparison of the median VPRR for the various MCSs showed that although each case had high reflectivity cores (45-55 dBZ) in the lowest 2 to 3 km, the more electrically active MCSs were characterized by smaller reflectivity lapse rates (decrease of reflectivity with height) in mixed phase region than the cores in the remaining systems. Based on existing theories of charge separation, the observation of high negative flash counts coincident with convective cores having small reflectivity lapse rates in the mixed phase region is consistent with the presence of large ice particles aloft. Positive CG flashes were mostly located in low reflectivity (< 30 dBZ near the-10C level) stratiform regions, independent of MCS life cycle stage or VPRR type. Several cases with reports of large hail also had high positive flash densities associated with high reflectivity cores. Devlin et al. (1995) compare 85 GHz brightness temperatures from the Special Sensor Microwave/Imager to lightning data for the same set of MCSs examined in this study. The results using radar and 85 GHz data indicate that the presence of large ice particles aloft is the common linkage between MCSs with lightning, with high radar reflectivity aloft, and large 85 GHz temperature depressions.

Climatological lightning characteristics of the Southern Rocky and Appalachian Mountain chains, a comparison of two distinct mountain effects  

E-Print Network (OSTI)

This study presents a high-resolution lightning climatology for southern portions of both the Rocky Mountains and the Appalachian Mountains. Data from the National Lightning Detection Network (NLDN) are analyzed to produce maps of average annual lightning flash density, positive flash density, percent positive flashes, median peak current, and multiplicity. Three-hourly increments are used to demonstrate the annual average diurnal evolution of flash density. Data are also divided into seasonal averages for the same three-hourly increments to describe the daily evolution of flash density for each of the four seasons: December-January-February, March-April-May, June-July-August, and September-October-November. The flash density analyses reveal opposite mountain-valley effects. In the Rocky Mountains, flash density enhancements occur over and near mountains and flash density minima occur in the valleys. In the Appalachians, the enhancements occur in the valleys, while minimums are noted over the mountains. The eastern edge of the Appalachian lightning suppression is determined to be a result of faster propagation of mountain-initiated convection. Weaker mountain breezes in the Appalachians are theorized to be the catalysts for this. The western edge of the suppression is the cumulative effect of consistent flash density gradients at the Appalachian's western slopes. A theory is presented which links this gradient to observations of high median peak currents. Statistical tests on flash density means show that the Appalachian suppression is significant. Multiple regressions predict lightning flash density from terrain characteristics. Vertical wind and thermodynamic profiles, horizontal temperature differences at summit levels, and average annual precipitation complete the study. From these data, a conceptual model is presented to describe the nature of the lightning evolution in each region, and explain the processes that lead to the end state. This study concludes that the differences between the patterns of lightning characteristics in the Southern Rockies and the Southern Appalachians are the cumulative effects of subtle differences in the diurnal evolution patterns. Furthermore, the Appalachian lightning suppression is a product of lightning propagation and storm evolution, rather than a suppression of convective initiation.

Exploration of the meteorological characteristics leading to the rapid cessation of cloud-to-ground lightning in winter cyclones along the East Coast of the United States  

E-Print Network (OSTI)

Intense winter East Coast cyclones are capable of producing large amounts of cloud-to-ground (CG) lightning. Few studies have thoroughly investigated winter lightning in the eastern United States. A phenomena common to most of these storms is a rapid cessation of CG lightning over land, north of North Carolina. The primary focus of this study was investigating the possible causes of this rapid cessation. A secondary objective was to explore the characteristics of the CG lightning produced by these storms. Seven intense East Coast cyclones from 1990 to 1996 were analyzed. Soundings, lower atmospheric temperature structure and accumulated precipitation were used to examine possible causes for this rapid cessation. Soundings also provided the vertical wind shear and temperatures used for linear regression analysis of the percentage of positive CG flashes. Further exploration of CG lightning characteristics included peak currents and flash densities. The major cause of the CG lightning cessation appears to be related to stability and not a suppression of charging due to cold lower atmospheric temperatures. The warm sector of all but one storm passed out into the Atlantic Ocean before making it north of North Carolina. This eliminated most of the surface instability for convection. Meanwhile, most soundings from Virginia on northward showed that conditions aloft were too stable to support elevated convection. Colder lower atmospheric temperatures were just representative of stable conditions that would not support convection. Unfortunately, heavy precipitation was not a good indicator of the CG lightning activity during these seven storms. Contrary to previous studies of winter thunderstorms, vertical wind shear of the horizontal wind was not a good predictor of the percentage of positive CG flashes. A combination of temperature and vertical wind shear data yielded better results. Finally, maximum peak current values showed a preference for the main CG lightning region south of Virginia. This study shed light on some of the aspens of winter CG lightning during intense East Coast cyclones. However, many more studies are needed within this field.

Evolution of cloud-to-ground lightning characteristics within the convective region of a midlatitude squall line  

E-Print Network (OSTI)

The relationship between storm dynamics and cloud-to-ground (CG) lightning characteristics in the convective region of the 10-11 June 1985 PRE-STORM (Preliminary Regional Experiment for Stormscale Operational and Research Meteorology) squall line has been examined over a period of 49 minutes. Lightning data from the National Severe Storms Laboratory lightning detection network combined with seven dual-Doppler analyses provided a unique dataset in which to study this Mesoscale Convective System (MCS). The mature phase of this system passed through the dual-Doppler analysis domain during a period when the convective region made an apparent transition to a weaker convective state. For the overall system, the peak in flash rates was shown to lag the maximum in the vertical velocity by roughly 1 0 to 20 minutes. Cross-sectional analyses revealed numerous examples of this time lag along with a coincidence of descending mid-toupper level reflectivity features and increasing CG flash rates. Along-line dynamical differences in the convective region may have contributed to significant spatial variations in the flash rate. The northern portion of the line featured stronger, more continuous updrafts along with a relative sparseness of lightning strikes. The southern section displayed weaker, but more discrete cell evolution which coincided with a rather uniform and substantial number of CG strikes.

An evaluation of lightning flash characteristics using LDAR and NLDN networks with warm season southeast Texas thunderstorms  

E-Print Network (OSTI)

A comparison of flash parameters from the National Lightning Detection Network (NLDN) is made with data obtained from the Houston Lightning Detection and Ranging II (LDAR) network. This research focuses on relating the peak current and number of strokes in a negative flash (multiplicity) of lightning with the spatial extent and mean altitude of three-dimensional lightning in 1407 flashes as mapped by the LDAR network. It is shown that increasing negative multiplicities over the range two through ten exhibit, on average, a higher flash extent with higher multiplicities. Singlestroke flashes have mean heights of nearly 2 km greater. Higher order multiplicities (2 to 10+) were correlated with mean source heights near 8 km. Increasing multiplicity tends to be associated with greater flash extents increasing more horizontally than vertically with a 50% to 70% increase in flash extent. No obvious relationship between peak current and flash extent was observed. Examining peak current and mean height shows that low current flashes (<10kA) exhibit higher mean heights. However, this may be due to intra-cloud only flashes being reported as cloud to ground events by the NLDN. Bipolar flashes do not show much variation with height and flash extent with the exception of negative-first bipolar flashes, which exhibited mean flash extents twice that of other types. Finally, the flash detection efficiency is 99.7% within 60 km of the network center.

Physical mechanism and numerical simulation of the inception of the lightning upward leader  

Science Conference Proceedings (OSTI)

The upward leader is a key physical process of the leader progression model of lightning shielding. The inception mechanism and criterion of the upward leader need further understanding and clarification. Based on leader discharge theory, this paper proposes the critical electric field intensity of the stable upward leader (CEFISUL) and characterizes it by the valve electric field intensity on the conductor surface, E{sub L}, which is the basis of a new inception criterion for the upward leader. Through numerical simulation under various physical conditions, we verified that E{sub L} is mainly related to the conductor radius, and data fitting yields the mathematical expression of E{sub L}. We further establish a computational model for lightning shielding performance of the transmission lines based on the proposed CEFISUL criterion, which reproduces the shielding failure rate of typical UHV transmission lines. The model-based calculation results agree well with the statistical data from on-site operations, which show the effectiveness and validity of the CEFISUL criterion.

Recovery signatures of lightning-associated VLF perturbations as a measure of the lower ionosphere  

SciTech Connect

A new model of the physical processes associated with subionospheric VLF signal perturbations caused by lightning-induced electron precipitation (LEP) bursts is developed to diagnose the state of the lower ionosphere (e.g., electron number density and rate coefficients for various chemical reactions) on the basis of measurements of VLF recovery signatures. The model accounts for the energy spectrum of the electron bursts precipitated by lightning-generated whistlers, the chemical relaxation of enhanced secondary ionization in the nightime D region due to LEP bursts, and quantitatively treats the resultant effects on propagation of the VLF signal in the Earth-ionosphere waveguide. Application of the model to experimental data obtained for the VLF propagation path from NPM station (Hawaii) to Palmer station (Antarctica) indicates that effective electron detachment rate {gamma}, enhanced secondary ionization profile (e.g., energy content of LEP bursts), as well as the ambient electron density distribution, may be estimated using observed subionospheric VLF recovery signatures. The effective detachment rate was identified as {approximately}10{sup 18} N s{sup {minus}1}, where N is total number density of neutrals. Model indicates in particular that the attachment-detachment processes play the dominant role in recovery of subionospheric VLF signal perturbations on timescales {approximately}100 s, and that the observed perturbations of the NPM-Palmer signal correspond to the LEP bursts consisting of relatively soft (< 250 keV) electrons. 33 refs., 24 figs.

A four-year summertime microburst climatology and relationship between microbursts and cloud-to ground lightning flash rate for the NASA Kennedy Space Center, Florida: 1995-1998  

E-Print Network (OSTI)

In order to ameliorate the forecasting of microbursts, the first summertime microburst climatology in the United States was produced. This climatology was based on a four year wind data base during the summer months (May - September) of 1995-1998 for 50 mesons wind towers that encompasses the KSC. An investigation into the microburst characteristics of frequency, diurnal variation, spatial variation, speed frequency distribution, and the wind direction was accomplished. Finally, an examination into the relationship between microbursts and lightning was conducted. A total of 282 microbursts were observed during this four-year period. There were 114 microburst days with 59 of these days having more than one microburst. The most prominent months of microbursts are June, July, and August with July being the most dominant. Several important characteristics of wind speed and direction were found. The median wind speed was 34 knots. The majority of microburst wind speeds fell within 25 and 44 knots. As the wind increases above 43 knots, the frequency decreases exponentially, reaching virtually zero at 65 knots. The predominant wind direction of the microbursts is from southeast through the west-northwest with a maximum from the southwest. The spatial variation of the microbursts revealed an interesting pattern. Some areas received a substantial amount of microbursts, while others received few, if any. It is hypothesized that this difference is due to the sea breeze interacting with the abundant over breezes causing the formation of convection over the same areas on a daily basis. The diurnal variation also uncovered a revealing pattern. The most favorable time for microbursts is between 1600 UTC (12 P.M. EDT) and 2200 UTC (6 P.M. EDT) with the peak occurring between 2000 UTC (4 P.M. EDT) and 2200 UTC (6 P.M. EDT). Directly after this peak the number of microbursts drops drastically. The investigation into the relationship between lightning and microbursts revealed that in most cases there was an evident increase in the CG flash rate up to 25 minutes prior to the microburst. Moreover, a clear peak omen occurred 5-10 minutes before the microburst. Thus, CG lightning may also improve microburst forecasting.

Relationships between tropical cyclone intensity and satellite based indicators of inner core convection: 85 GHz ice scattering signature and lightning  

E-Print Network (OSTI)

A key component in the maintenance and intensification of tropical cyclones is the transverse circulation, which transports mass and momentum and provides latent heat release via inner core convective updrafts. This study examines these updrafts indirectly, using satellite-borne observations of the scattering of upwelling microwave radiation by precipitation sized ice and satellite-borne observations of lightning. The observations are then compared to tropical cyclone intensity and the resulting relationships are assessed. The size of ice particles is tied to updraft strength, in that stronger updrafts produce more supercooled liquid water, leading to larger graupel through riming. Large graupel and a high supercooled liquid water content are necessary ingredients for charge separation, leading to lightning. Various parameters derived from the inner core ice scattering signature are computed for regions encircling hurricanes and typhoons, and observations of lightning activity or inactivity are analyzed. As expected, increasing ice scattering signature is found to correspond to increasing tropical cyclone intensity. However, the highest correlations do not involve indicators of convective intensity, as they were expected to. Instead, the highest correlations with tropical cyclone intensity result from the ice scattering signature parameters most closely associated with the areal extent of at least moderate precipitation rates. Correlations tend to be of the same sign for both present cyclone intensity at the time of the satellite overpass and subsequent intensity change. Correlations are higher for future cyclone intensity than for either of these. These correlations are much higher for the Atlantic and the Eastern North Pacific than for the Western North Pacific. It is hypothesized that processes involved with the most intense or rapidly intensifying tropical cyclones (more commonly found in the Western North Pacific) are responsible for these differences. The lightning observations are more limited than the microwave observations, because the short amount of time in which lightning can be detected may not adequately represent a particular storms electrical activity. These observations reveal no clear relationships between electrical activity and tropical cyclone intensity. In the examination of case studies, the paradoxical situation of much greater lightning activity in rainbands than in eyewalls is noted.

Failure analysis of rutile sleeves in MC3080 lightning arrestor connectors.  

Science Conference Proceedings (OSTI)

The purpose of this SAND Report is to document efforts in the extraction and failure analyses of sleeve-style Lightning Arrestor Connectors (LACs). Several MC3080 and MC3079 LACs were recovered from the field and tested as part of the Enhanced Surveillance Campaign. A portion of these LACs failed retesting. Terry Ernest (01733), the LAC Component Engineer, provided eleven MC3080 LACs for evaluation where four of the LACs failed IR/DCW and one failed FRB requirements. The extraction of rutile sleeves from failed LACs was required to determine the source of failure. Rutile sleeves associated with connector function failures were examined for cracks, debris as well as any other anomalies which could have caused the LAC to not function properly. Sleeves that failed FRB or that experienced high FRB exhibited high symmetry, smooth surface, long-flow amicon, and slightly over-sized inside diameter. LACs that failed DCW or IR requirements had rutile sleeves that exhibited breakdown tracks.

Subionospheric VLF imaging of lightning-induced electron precipitation from the magnetosphere  

SciTech Connect

High-resoluton measurements of subionospheric VLF signals at multiple sites are used as a new tool to assess the spatial distribution and occurrence of ionospheric disturbances associated with lightning-induced electron precipitation. Simultaneous observations in California, Saskatchewan, and Quebec of VLF signals from multiple sources allow the monitoring of event activity over a course grid covering the continental US. Association of the observed VLF signal perturbations with lightning is often made on the basis of time correlation with prominent radio atmospherics. Simultaneous observations of individual events on subionospheric paths that cross one another are used to locate the disturbed ionospheric region(s). Absence of perturbations on nearby paths permits assessment of the spatial exstent of the region with a varying degree of accuracy, depending on the distribution of signal paths. In one case distinctly different onset delays (with respect to causative discharges) consistent with predictions of whistler-particle scattering theory were found, and were interpreted as being due to two separate regions separated in L value by {approximately} 0.4 L being excited in individual events. Occurrence statistics over the course of October 1987 exhibit generally higher levels of activity at the lower-latitude end of the 2 {lt} L {lt} 4 range, although it is difficult to separately assess the role of the source ligntning distribution. Occurrence statistics of simultaneous events on crossing paths are consistent with the spatial extent of the disturbed ionospheric regions being less than a few hundred kilometers. The occurrence statistics also suggest that scattering from disturbances located at distances of {gt} 100 km off the great circle paths is not significant.

Lightning protection requirements of SF/sub 6/ substation determined by hybrid simulator. [115/345 kv station  

SciTech Connect

The development of a hybrid computer simulation which can provide the type and quantity of data necessary for determining the behavior of lightning-caused surges traveling through substations is discussed. Results from a specific application on a 115-kV/345-kV station are presented. The results show that the simulation of SF/sub 6/ substations during lightning-caused surges is ideally accomplished by hybrid computer. The quantity of data for complete substation analysis may be gathered efficiently. In addition, digital graphical summaries provide quick insight into substation behavior. The application of this method to simple configurations has shown the previous assumptions must be carefully reviewed. For example, it is shown by computer simulation and analytical hand calculation that the surges with the steepest wave fronts may not produce the highest substation voltages. It is concluded that this hybrid simulation is an excellent tool in the determination of SF/sub 6/ substation response to lightning-caused surges. (LCL)

SF6 dielectric behavior in a high voltage circuit breaker at low temperature under lightning impulses  

Science Conference Proceedings (OSTI)

This work concerns the study of the dielectric and thermodynamic behavior of SF{sub 6} in a 145 kV circuit breaker subjected to lightning impulse voltages in both polarities at temperatures varying from ambient (20 C) to {minus}45 C. The filling of the circuit breaker with SF{sub 6} is carried out at the reference point: T = 15 C, P = 6 bars abs. and d = 39.6 kg/m{sup 3}. Devices allowing to detect the appearance of local condensation of SF{sub 6} and to identify the breakdown between the circuit-breaker contacts and the flashover outside the circuit-breaker, are presented. The experimental results show a general tendency to a decrease in the U{sub 50%} voltage when the temperature is decreased at constant density (a decrease by about 5% when the temperature was decreased from +20 C to {minus}25 C). Such a variation would not have a significant influence in industrial practice. Even if this variation is very weak, it also appears from the obtained results that the gas density is not the only parameter which has an influence on the electric strength of the gas. However, to compare results at different temperatures, it would be better to make it at constant density and not at constant pressure, to avoid the dependency of the ratio (E/N) on N (where E is the electric strength and N the density). On the other hand, it seems that the presence of the liquid in the circuit breaker is not a penalizing parameter. The distribution of the electric field corresponding to the geometrical configuration of the studied circuit-breaker is also presented.

Three-dimensional modeling of subionospheric VLF propagation in the presence of localized D region perturbations associated with lightning  

SciTech Connect

A theoretical model of single-mode, subionospheric VLF wave propagation in the presence of localized perturbations of the nighttime D region has been developed. Such perturbations could be produced, for example, by lightning-induced electron precipitation associated with a characteristic type of phase or amplitude perturbation in VLF signals known as Trimpi events. The model assumes that the ionospheric perturbation is slowly varying in the horizontal plane and that mode-coupling is therefore negligible, and accounts for (1) effects of perturbations with finite extent in the dimension transverse to the great circle (GC) path between transmitter and receiver, and (2) effects of perturbations which lie off the GC path as well as on it. The formulation used for the numerical calculations depends significantly on the mode refractive index of the ambient Earth-ionosphere waveguide and the mode refractive index in the region of the perturbation. In the calculations values for the mode refractive index are determined from the electron-density-versus-altitude profiles of both the ambient and perturbed ionospheres. Values for changes in the amplitude and phase of a received signal were obtained from the model and compared with amplitude and phase measurements of a VLF signal received at Palmer Station, Antarctica, from the NPM transmitter (23.4 kHz) in Hawaii during energetic electron precipitation events.

Decontamination & decommissioning focus area  

Science Conference Proceedings (OSTI)

In January 1994, the US Department of Energy Office of Environmental Management (DOE EM) formally introduced its new approach to managing DOE`s environmental research and technology development activities. The goal of the new approach is to conduct research and development in critical areas of interest to DOE, utilizing the best talent in the Department and in the national science community. To facilitate this solutions-oriented approach, the Office of Science and Technology (EM-50, formerly the Office of Technology Development) formed five Focus AReas to stimulate the required basic research, development, and demonstration efforts to seek new, innovative cleanup methods. In February 1995, EM-50 selected the DOE Morgantown Energy Technology Center (METC) to lead implementation of one of these Focus Areas: the Decontamination and Decommissioning (D & D) Focus Area.

AREA RADIATION MONITOR  

DOE Patents (OSTI)

S>An improved area radiation dose monitor is designed which is adapted to compensate continuously for background radiation below a threshold dose rate and to give warning when the dose integral of the dose rate of an above-threshold radiation excursion exceeds a selected value. This is accomplished by providing means for continuously charging an ionization chamber. The chamber provides a first current proportional to the incident radiation dose rate. Means are provided for generating a second current including means for nulling out the first current with the second current at all values of the first current corresponding to dose rates below a selected threshold dose rate value. The second current has a maximum value corresponding to that of the first current at the threshold dose rate. The excess of the first current over the second current, which occurs above the threshold, is integrated and an alarm is given at a selected integrated value of the excess corresponding to a selected radiation dose.

Solderability study of 63Sn-37Pb on zinc-plated and cadmium-plated stainless steel for the MC4636 lightning arrestor connector.  

Science Conference Proceedings (OSTI)

Cadmium plating on metal surfaces is commonly used for corrosion protection and to achieve good solderability on the 304L stainless steel shell of the MC4636 lightning arrestor connector (LAC) for the W76-1 system. This study examined the use of zinc as a potential substitute for the cadmium protective surface finish. Tests were performed with an R and RMA flux and test temperatures of 230 C, 245 C, and 260 C. Contact angle, {theta}{sub c}, served as the generalized solderability metric. The wetting rate and wetting time parameters were also collected. The solderability ({theta}{sub c}) of the Erie Plating Cd/Ni coatings was better than that of similar Amphenol coatings. Although the {theta}{sub c} data indicated that both Cd/Ni platings would provide adequate solderability, the wetting rate and wetting time data showed the Amphenol coatings to have better performance. The Zn/Ni coatings exhibited non-wetting under all flux and temperature conditions. Based on the results of these tests, it has been demonstrated that zinc plating is not a viable alternate to cadmium plating for the LAC connectors.

Geothermal Resource area 9 encompasses all of Nye County, Nevada. Within this area there are many different known geothermal sites ranging in temperature from 70/sup 0/ to over 265/sup 0/ F. Fifteen of the more major sites have been selected for evaluation in this Area Development Plan. Various potential uses of the energy found at each of the resource sites discussed in this Area Development Plan were determined after evaluating the area's physical characteristics, land ownership and land use patterns, existing population and projected growth rates, and transportation facilities, and comparing those with the site specific resource characteristics. The uses considered were divided into five main categories: electrical generation, space heating, recreation, industrial process heat, and agriculture. Within two of these categories certain subdivisions were considered separately. The findings about each of the 15 geothermal sites considered in this Area Development Plan are summarized.

Tech Area II: A History  

E-Print Network (OSTI)

This report documents the history of the major buildings in Sandia National Laboratories' Technical Area II. It was prepared in support of the Department of Energy's compliance with Section 106 of the National Historic Preservation Act. Technical Area II was designed and constructed in 1948 specifically for the final assembly of the non-nuclear components of nuclear weapons, and was the primary site conducting such assembly until 1952. Both the architecture and location of the oldest buildings in the area reflect their original purpose. Assembly activities continued in Area II from 1952 to 1957, but the major responsibility for this work shifted to other sites in the Atomic Energy Commission's integrated contractor complex. Gradually, additional buildings were constructed and the original buildings were modified. After 1960, the Area's primary purpose was the research and testing of high-explosive components for nuclear weapons. In 1994, Sandia constructed new facilities for work on hi...

Geothermal resource area 3: Elko County. Area development plan  

DOE Green Energy (OSTI)

Geothermal Resource Area 3 includes all of the land in Elko County, Nevada. There are in excess of 50 known thermal anomalies in this area. Several of the more major resources have been selected for detailed description and evaluation in this Area Development Plan. The other resources are considered too small, too low in temperature, or too remote to be considered for development in the near future. Various potential uses of the energy found at each of the studied resource sites in Elko County were determined after evaluating the area's physical characteristics; the land ownership and land use patterns; existing population and projected growth rates; transportation facilities and energy requirements. These factors were then compared with resource site specific data to determine the most likely uses of the resource. The uses considered in this evaluation were divided into five main categories: electrical generation, space heating, recreation, industrial process heat, and agriculture. Within two of these categories several subdivisions were considered separately. It was determined that several of the geothermal resources evaluated in the Area Development Plan could be commercially developed. The potential for development for the seven sites considered in this study is summarized.

Geothermal Resource Area 11 includes all of the land in Clark County, Nevada. Within this area are nine geothermal anomalies: Moapa Area, Las Vegas Valley, Black Canyon, Virgin River Narrows, Roger's Springs, Indian Springs, White Rock Springs, Brown's Spring, and Ash Creek Spring. All of the geothermal resources in Clark County have relatively low temperatures. The highest recorded temperature is 145{sup 0}F at Black Canyon. The temperatures of the other resources range from 70 to 90{sup 0}F. Because of the low temperature of the resources and, for the most part, the distance of the resources from any population base, the potential for the development of the resources are considered to be somewhat limited.

Innovation investment area: Technology summary  

Science Conference Proceedings (OSTI)

The mission of Environmental Management`s (EM) Office of Technology Development (OTD) Innovation Investment Area is to identify and provide development support for two types of technologies that are developed to characterize, treat and dispose of DOE waste, and to remediate contaminated sites. They are: technologies that show promise to address specific EM needs, but require proof-of-principle experimentation; and (2) already proven technologies in other fields that require critical path experimentation to demonstrate feasibility for adaptation to specific EM needs. The underlying strategy is to ensure that private industry, other Federal Agencies, universities, and DOE National Laboratories are major participants in developing and deploying new and emerging technologies. To this end, about 125 different new and emerging technologies are being developed through Innovation Investment Area`s (IIA) two program elements: RDDT&E New Initiatives (RD01) and Interagency Agreements (RD02). Both of these activities are intended to foster research and development partnerships so as to introduce innovative technologies into other OTD program elements for expedited evaluation.

Bis[(1S)-1 4-azanediyl-1-(9-deazaadenin-9-yl)-1 4-dideoxy-5-methylsulfanyl-D-ribitol] tetrakis(hydrochloride) monohydrate: structure DFT energy and ligand docking results of a potent methylthioadenosine phosphorylase inhibitor found in different  

SciTech Connect

The title compound, abbreviated as 5'ThiomethylImmA, is a potent inhibitor of methylthioadenosine phosphorylase [Singh et al. (2004). Biochemistry, 43, 9-18]. The synchrotron study reported here shows that the hydrochloride salt crystallizes with two independent, nearly superimposable, dications as a monohydrate with formula 2C{sub 12}H{sub 19}N{sub 5}O{sub 2}S{sup 2+}{center_dot}4Cl{sup -}{center_dot}H{sub 2}O. Hydrogen bonding utilizing the H atoms of the dication is found to favor certain molecular conformations in the salt, which are significantly different from those found as bound in the enzyme. Ligand docking studies starting from either of these dications or related neutral structures successfully place the conformationally revised structures in the enzyme active site but only under particular hydrogen-bonding and molecular flexibility criteria. Density functional theory calculations verify the energy similarity of the indendent cations and confirm the significant energy cost of the required conformation change to the enzyme bound form. The results suggest the using crystallographically determined free ligand coordinates as starting parameters for modelling may have serious limitations.

Tanks focus area. Annual report  

SciTech Connect

The U.S. Department of Energy Office of Environmental Management is tasked with a major remediation project to treat and dispose of radioactive waste in hundreds of underground storage tanks. These tanks contain about 90,000,000 gallons of high-level and transuranic wastes. We have 68 known or assumed leaking tanks, that have allowed waste to migrate into the soil surrounding the tank. In some cases, the tank contents have reacted to form flammable gases, introducing additional safety risks. These tanks must be maintained in the safest possible condition until their eventual remediation to reduce the risk of waste migration and exposure to workers, the public, and the environment. Science and technology development for safer, more efficient, and cost-effective waste treatment methods will speed up progress toward the final remediation of these tanks. The DOE Office of Environmental Management established the Tanks Focus Area to serve as the DOE-EM`s technology development program for radioactive waste tank remediation in partnership with the Offices of Waste Management and Environmental Restoration. The Tanks Focus Area is responsible for leading, coordinating, and facilitating science and technology development to support remediation at DOE`s four major tank sites: the Hanford Site in Washington State, Idaho National Engineering and Environmental Laboratory in Idaho, Oak Ridge Reservation in Tennessee, and the Savannah River Site in South Carolina. The technical scope covers the major functions that comprise a complete tank remediation system: waste retrieval, waste pretreatment, waste immobilization, tank closure, and characterization of both the waste and tank. Safety is integrated across all the functions and is a key component of the Tanks Focus Area program.

History of 100-B Area  

SciTech Connect

The initial three production reactors and their support facilities were designated as the 100-B, 100-D, and 100-F areas. In subsequent years, six additional plutonium-producing reactors were constructed and operated at the Hanford Site. Among them was one dual-purpose reactor (100-N) designed to supply steam for the production of electricity as a by-product. Figure 1 pinpoints the location of each of the nine Hanford Site reactors along the Columbia River. This report documents a brief description of the 105-B reactor, support facilities, and significant events that are considered to be of historical interest. 21 figs.

Ashland Area Support Substation Project  

Science Conference Proceedings (OSTI)

The Bonneville Power Administration (BPA) provides wholesale electric service to the City of Ashland (the City) by transferring power over Pacific Power Light Company's (PP L) 115-kilovolt (kV) transmission lines and through PP L's Ashland and Oak Knoll Substations. The City distributes power over a 12.5-kV system which is heavily loaded during winter peak periods and which has reached the limit of its ability to serve peak loads in a reliable manner. Peak loads under normal winter conditions have exceeded the ratings of the transformers at both the Ashland and Oak Knoll Substations. In 1989, the City modified its distribution system at the request of PP L to allow transfer of three megawatts (MW's) of electric power from the overloaded Ashland Substation to the Oak Knoll Substation. In cooperation with PP L, BPA installed a temporary 6-8 megavolt-amp (MVA) 115-12.5-kV transformer for this purpose. This additional transformer, however, is only a temporary remedy. BPA needs to provide additional, reliable long-term service to the Ashland area through additional transformation in order to keep similar power failures from occurring during upcoming winters in the Ashland area. The temporary installation of another 20-MVA mobile transformer at the Ashland Substation and additional load curtailment are currently being studied to provide for sustained electrical service by the peak winter period 1992. Two overall electrical plans-of-service are described and evaluated in this report. One of them is proposed for action. Within that proposed plan-of-service are location options for the substation. Note that descriptions of actions that may be taken by the City of Ashland are based on information provided by them.

Safety analysis, 200 Area, Savannah River Plant: Separations area operations  

Science Conference Proceedings (OSTI)

The nev HB-Line, located on the fifth and sixth levels of Building 221-H, is designed to replace the aging existing HB-Line production facility. The nev HB-Line consists of three separate facilities: the Scrap Recovery Facility, the Neptunium Oxide Facility, and the Plutonium Oxide Facility. There are three separate safety analyses for the nev HB-Line, one for each of the three facilities. These are issued as supplements to the 200-Area Safety Analysis (DPSTSA-200-10). These supplements are numbered as Sup 2A, Scrap Recovery Facility, Sup 2B, Neptunium Oxide Facility, Sup 2C, Plutonium Oxide Facility. The subject of this safety analysis, the, Plutonium Oxide Facility, will convert nitrate solutions of {sup 238}Pu to plutonium oxide (PuO{sub 2}) powder. All these new facilities incorporate improvements in: (1) engineered barriers to contain contamination, (2) barriers to minimize personnel exposure to airborne contamination, (3) shielding and remote operations to decrease radiation exposure, and (4) equipment and ventilation design to provide flexibility and improved process performance.

Alderwood Area Service Environmental Assessment.  

SciTech Connect

Bonneville Power Administration's (BPA's) proposal to build a new 115-kV transmission line and 115-12.5-kV, 25-MW substation in the Alderwood, Oregon, area is discussed in the attached Environmental Assessment. The proposed substation site has been relocated about 500 feet east of the site outlined in the Environmental Assessment, but in the same field. This is not a substantial change relevant to environmental concerns. Environmental impacts of the new site differ only in that: Two residences will be visually affected. The substation will be directly across Highway 36 from two houses and would be seen in their primary views. This impact will be mitigated by landscaping the substation to create a vegetative screen. To provide access to the new site and provide for Blachly-Lane Cooperative's distribution lines, a 60-foot-wide right-of-way about 200 feet long will be needed. The total transmission line length will be less than originally planned. However, the tapline into the substation will be about 50 feet longer. 4 figs.
