Lightning Lightning Nature Bulletin No. 458-A May 20, 1972 Forest Preserve District of Cook County George W. Dunne, President Roland F. 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.

Burns Prevention  

NLE Websites -- All DOE Office Websites (Extended Search)

Burns Burns Burns can result from everyday things and activities in your home. The most common causes of burns are from scalds (steam, hot bath water, hot drinks and foods), fire, chemicals, electricity and overexposure to the sun. Some burns may be more serious than others. The severity of the burn is based on the depth of the burn. First degree burns are the least severe, and third degree burns are the most severe. Call 911 or seek medical attention if you are unsure of how severe your burn is. All burns are susceptible to tetanus (lockjaw). Get a tetanus shot every 10 years. If your last shot was 5 years ago, talk to your doctor - you may need a booster shot. Causes of Burns: Scalds Scalding injuries and burns are caused by hot tap water, hot beverages and food, and steam.

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 cell’s 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.

Burning plasmas  

SciTech Connect

The fraction of fusion-reaction energy that is released in energetic charged ions, such as the alpha particles of the D-T reaction, can be thermalized within the reacting plasma and used to maintain its temperature. This mechanism facilitates the achievement of very high energy-multiplication factors Q, but also raises a number of new issues of confinement physics. To ensure satisfactory reaction operation, three areas of energetic-ion interaction need to be addressed: single-ion transport in imperfectly symmetric magnetic fields or turbulent background plasmas; energetic-ion-driven (or stabilized) collective phenomena; and fusion-heat-driven collective phenomena. The first of these topics is already being explored in a number of tokamak experiments, and the second will begin to be addressed in the D-T-burning phase of TFTR and JET. Exploration of the third topic calls for high-Q operation, which is a goal of proposed next-generation plasma-burning projects. Planning for future experiments must take into consideration the full range of plasma-physics and engineering R D areas that need to be addressed on the way to a fusion power demonstration.

BNL | Biomass Burns  

NLE Websites -- All DOE Office Websites (Extended Search)

Biomass Burn Observation Project (BBOP) Biomass Burn Observation Project (BBOP) Aerosols from biomass burning are recognized to perturb Earth's climate through the direct effect (both scattering and absorption of incoming shortwave radiation), the semi-direct effect (evaporation of cloud drops due to absorbing aerosols), and indirect effects (by influencing cloud formation and precipitation. Biomass burning is an important aerosol source, providing an estimated 40% of anthropogenically influenced fine carbonaceous particles (Bond, et al., 2004; Andrea and Rosenfeld, 2008). Primary organic aerosol (POA) from open biomass burns and biofuel comprises the largest component of primary organic aerosol mass emissions at northern temperate latitudes (de Gouw and Jimenez, 2009).

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.

Lightning Arrestor Connectors Production Readiness  

SciTech Connect

The Lightning Arrestor Connector (LAC), part “M”, presented opportunities to improve the processes used to fabricate LACs. The A## LACs were the first production LACs produced at the KCP, after the product was transferred from Pinnellas. The new LAC relied on the lessons learned from the A## LACs; however, additional improvements were needed to meet the required budget, yield, and schedule requirements. Improvement projects completed since 2001 include Hermetic Connector Sealing Improvement, Contact Assembly molding Improvement, development of a second vendor for LAC shells, general process improvement, tooling improvement, reduction of the LAC production cycle time, and documention of the LAC granule fabrication process. This report summarizes the accomplishments achieved in improving the LAC Production Readiness.

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.

Sun tanning/burning  

NLE Websites -- All DOE Office Websites (Extended Search)

Sun tanning/burning Sun tanning/burning Name: Richardo Cossyleon Location: N/A Country: N/A Date: N/A Question: Why doesn't the sun affect or burn people with dark pigment in their skin? Replies: Good question! The pigment, melanin, is more toward the surface of the upper skin layer and absorbs ultraviolet rays from the Sun or artificial sources. This absorption protects the lower layers from damage and inflammation (burning). A very dark skinned person may have over a 1000X the protection from UV compared to a fair skinned person. Fair skinned people should use sun-block lotions especially early in the warm season AND keep exposure to the sun, particularly at midday, to less than 30 min. Even if a person gets a good tan, the sun's UV will age the skin over time. It will get wrinkled and develop age lines, etc. after many years of exposure. Moderation is the key!

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.

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.

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.

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.

Optimal Mechansim Design and Money Burning  

E-Print Network (OSTI)

Mechanism design is now a standard tool in computer science for aligning the incentives of self-interested agents with the objectives of a system designer. There is, however, a fundamental disconnect between the traditional application domains of mechanism design (such as auctions) and those arising in computer science (such as networks): while monetary transfers (i.e., payments) are essential for most of the known positive results in mechanism design, they are undesirable or even technologically infeasible in many computer systems. Classical impossibility results imply that the reach of mechanisms without transfers is severely limited. Computer systems typically do have the ability to reduce service quality--routing systems can drop or delay traffic, scheduling protocols can delay the release of jobs, and computational payment schemes can require computational payments from users (e.g., in spam-fighting systems). Service degradation is tantamount to requiring that users burn money}, and such ``payments'' can...

Hydrogen Burning on Magnetar Surfaces  

E-Print Network (OSTI)

We compute the rate of diffusive nuclear burning for hydrogen on the surface of a "magnetar" (Soft Gamma-Ray Repeater or Anomalous X-Ray Pulsar). We find that hydrogen at the photosphere will be burned on an extremely rapid timescale of hours to years, depending on composition of the underlying material. Improving on our previous studies, we explore the effect of a maximally thick "inert" helium layer, previously thought to slow down the burning rate. Since hydrogen diffuses faster in helium than through heavier elements, we find this helium buffer actually increases the burning rate for magnetars. We compute simple analytic scalings of the burning rate with temperature and magnetic field for a range of core temperature. We conclude that magnetar photospheres are very unlikely to contain hydrogen. This motivates theoretical work on heavy element atmospheres that are needed to measure effective temperature from the observed thermal emission and constrains models of AXPs that rely on magnetar cooling through thick light element envelopes.

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.

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.

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.

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.

Actinide Burning in CANDU Reactors  

Science Conference Proceedings (OSTI)

Actinide burning in CANDU reactors has been studied as a method of reducing the actinide content of spent nuclear fuel from light water reactors, and thereby decreasing the associated long term decay heat load. In this work simulations were performed of actinides mixed with natural uranium to form a mixed oxide (MOX) fuel, and also mixed with silicon carbide to form an inert matrix (IMF) fuel. Both of these fuels were taken to a higher burnup than has previously been studied. The total transuranic element destruction calculated was 40% for the MOX fuel and 71% for the IMF. (authors)

Uniform-burning matrix burner  

DOE Patents (OSTI)

Computer simulation was used in the development of an inward-burning, radial matrix gas burner and heat pipe heat exchanger. The burner and exchanger can be used to heat a Stirling engine on cloudy days when a solar dish, the normal source of heat, cannot be used. Geometrical requirements of the application forced the use of the inward burning approach, which presents difficulty in achieving a good flow distribution and air/fuel mixing. The present invention solved the problem by providing a plenum with just the right properties, which include good flow distribution and good air/fuel mixing with minimum residence time. CFD simulations were also used to help design the primary heat exchanger needed for this application which includes a plurality of pins emanating from the heat pipe. The system uses multiple inlet ports, an extended distance from the fuel inlet to the burner matrix, flow divider vanes, and a ring-shaped, porous grid to obtain a high-temperature uniform-heat radial burner. Ideal applications include dish/Stirling engines, steam reforming of hydrocarbons, glass working, and any process requiring high temperature heating of the outside surface of a cylindrical surface.

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.

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.

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.

Monitoring Soil Erosion on a Burned Site in the Mojave-Great Basin Transition Zone: Final Report for the Jacob Fire Site  

SciTech Connect

A historic return interval of 100 years for large fires in the U.S. southwestern deserts is being replaced by one where fires may reoccur as frequently as every 20 to 30 years. The shortened return interval, which translates to an increase in fires, has implications for management of Soil Corrective Action Units (CAUs) and Corrective Action Sites (CASs) for which the Department of Energy, National Nuclear Security Administration Nevada Field Office has responsibility. A series of studies was initiated at uncontaminated analog sites to better understand the possible impacts of erosion and transport by wind and water should contaminated soil sites burn. The first of these studies was undertaken at the Jacob Fire site approximately 12 kilometers (7.5 miles) north of Hiko, Nevada. A lightning-caused fire burned approximately 200 hectares during August 6-8, 2008. The site is representative of a transition between Mojave and Great Basin desert ecoregions on the Nevada National Security Site (NNSS), where the largest number of Soil CAUs/CASs are located. The area that burned at the Jacob Fire site was primarily a Coleogyne ramosissima (blackbrush) and Ephedra nevadensis (Mormon tea) community, also an abundant shrub assemblage in the similar transition zone on the NNSS. This report summarizes three years of measurements after the fire. Seven measurement campaigns at the Jacob Fire site were completed. Measurements were made on burned ridge (upland) and drainage sites, and on burned and unburned sites beneath and between vegetation. A Portable In-Situ Wind Erosion Lab (PI-SWERL) was used to estimate emissions of suspended particles at different wind speeds. Context for these measurements was provided through a meteorological tower that was installed at the Jacob Fire site to obtain local, relevant environmental parameters. Filter samples, collected from the exhaust of the PI-SWERL during measurements, were analyzed for chemical composition. Runoff and water erosion were quantified through a series of rainfall/runoff simulation tests in which controlled amounts of water were delivered to the soil surface in a specified amount of time. Runoff data were collected from understory and interspace soils on burned ridge and drainage areas. Runoff volume and suspended sediment in the runoff were sampled; the particle size distribution of the sediment was determined by laboratory analysis. Several land surface and soil characteristics associated with runoff were integrated by the calculation of site-specific curve numbers. Several vegetation surveys were conducted to assess post-burn recovery. Data from plots in both burned and unburned areas included species identification, counts, and location. Characterization of fire-affected area included measures at both the landscape scale and at specific sites. Although wind erosion measurements indicate that there are seasonal influences on almost all parameters measured, several trends were observed. PI-SWERL measurements indicated the potential for PM10 windblown dust emissions was higher on areas that were burned compared to areas that were not. Among the burned areas, understory soils in drainage areas were the most emissive, and interspace soils along burned ridges were least emissive. By 34 months after the burn (MAB), at the end of the study, emissions from all burned soil sites were virtually indistinguishable from unburned levels. Like the amount of emissions, the chemical signature of the fire (indicated by the EC-Soil ratio) was elevated immediately after the fire and approached pre-burn levels by 24 MAB. Thus, the potential for wind erosion at the Jacob Fire site, as measured by the amount and type of emissions, increased significantly after the fire and returned to unburned levels by 24 MAB. The effect of fire on the potential for water erosion at the Jacob Fire site was more ambiguous. Runoff and sediment from ridge interspace soils and unburned interspace soils were similar throughout the study period. Seldom, if ever, did runoff and sediment occur in burned drainage area soils.

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 -10°C 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 -10°C 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.

Reactive burn models and ignition & growth concept  

SciTech Connect

Plastic-bonded explosives are heterogeneous materials. Experimentally, shock initiation is sensitive to small amounts of porosity, due to the formation of hot spots (small localized regions of high temperature). This leads to the Ignition and Growth concept, introduced by Lee and Tarver in 1980, as the basis for reactive burn models. A homogeneized burn rate needs to account for three mesoscale physical effects (i) the density of burnt hot spots, which depends on the lead shock strength; (ii) the growth of the burn fronts triggered by hot spots, which depends on the local deflagration speed; (iii) a geometric factor that accounts for the overlap of deflagration wavelets from adjacent hot spots. These effects can be combined and the burn model defined by specifying the reaction progress variable {lambda}(t) as a function of a dimensionless reaction length {tau}{sub hs}(t)/{ell}{sub hs}, rather than by xpecifying an explicit burn rate. The length scale {ell}{sub hs} is the average distance between hot spots, which is proportional to [N{sub hs}(P{sub s})]{sup -1/3}, where N{sub hs} is the number density of hot spots activated by the lead shock. The reaction length {tau}{sub hs}(t) = {line_integral}{sub 0}{sup t} D(P(t'))dt' is the distance the burn front propagates from a single hot spot, where D is the deflagration speed and t is the time since the shock arrival. A key implementation issue is how to determine the lead shock strength in conjunction with a shock capturing scheme. They have developed a robust algorithm for this purpose based on the Hugoniot jump condition for the energy. The algorithm utilizes the time dependence of density, pressure and energy within each cell. The method is independent of the numerical dissipation used for shock capturing. It is local and can be used in one or more space dimensions. The burn model has a small number of parameters which can be calibrated to fit velocity gauge data from shock initiation experiments.

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.

An Interactive Simulation Framework for Burning Objects  

E-Print Network (OSTI)

We present a simulation framework to integrate several aspects of the combustion and burning process in a unified and modular manner. A simple three gas flame model is used to simulate a combustion process, while air motion is simulated as a single moving fluid. Solid objects inside the simulation domain can catch fire and start burning. Heat information is transferred from the fluid simulator to a solid simulator, while the solid simulator injects fuel into the fluid simulation. We also present a simple yet effective method for modeling of object decomposition under combustion using level set methods. The interaction between modules is presented as well as a discussion of fluid-solid coupling. All simulation modules run together at interactive rates, enabling the user to tweak the simulation parameters and setup for desired behavior 1. 1

Operation Redwing. Project 4. 1. Chorioretinal burns  

SciTech Connect

This Redwing project was designed to furnish supplemental information on the requirements for protection against retinal burns, using both rabbits and monkeys as experimental animals. Chorioretinal burns were produced by various segments of the thermal pulse. This was accomplished by two series of time-fractionating shutters. The first group, the early closing shutters, were open at time zero and closed at increasing intervals of time. The second series, the delayed-opening shutters, were closed at time zero and subsequently opened for preselected time increments during the flash. The feasibility of protection by fixed-density optical filters was explored. Two types of protective electronic shutters were field tested. Additional objectives were to: (1) determine whether blink reflexes would prevent chorioretinal burns; (2) ascertain which portions of the time-intensity pulse can produce thermal injury to the retina and choroid of the eye; (3) determine the time required for blink reflex in rabbits and monkeys exposed to the extreme light intensity of the nuclear detonations; (4) explore the feasibility of ocular protection by means of fixed-density optical filters or combinations of filters; and (5) tests, under field conditions, protective shutter devices that are in the developmental state and are designed to close more rapidly than the blink reflex.

U.S. BURNING PLASMA ORGANIZATION ACTIVITIES  

Science Conference Proceedings (OSTI)

The national U.S. Burning Plasma Organization (USBPO) was formed to provide an umbrella structure in the U.S. fusion science research community. Its main purpose is the coordination of research activities in the U.S. program relevant to burning plasma science and preparations for participation in the international ITER experiment. This grant provided support for the continuing development and operations of the USBPO in its first years of existence. A central feature of the USBPO is the requirement for broad community participation in and governance of this effort. We concentrated on five central areas of activity of the USBPO during this grant period. These included: 1) activities of the Director and support staff in continuing management and development of the USBPO activity; 2) activation of the advisory Council; 3) formation and initial research activities of the research community Topical Groups; 4) formation of Task Groups to perform specific burning plasma related research and development activities; 5) integration of the USBPO community with the ITER Project Office as needed to support ITER development in the U.S.

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.

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.

Neutrino-Accelerated Hot Hydrogen Burning

We examine the effects of significant electron anti-neutrino fluxes on hydrogen burning. Specifically, we find that the bottleneck weak nuclear reactions in the traditional pp-chain and the hot CNO cycle can be accelerated by anti-neutrino capture, increasing the energy generation rate. We also discuss how anti-neutrino capture reactions can alter the conditions for break out into the rp-process. We speculate on the impact of these considerations for the evolution and dynamics of collapsing very- and super- massive compact objects.

Erosion Potential of a Burn Site in the Mojave-Great Basin Transition Zone: Interim Summary of One Year of Measurements  

Science Conference Proceedings (OSTI)

A historic return interval of 100 years for large fires in deserts in the Southwest U.S. is being replaced by one where fires may reoccur as frequently as every 20 to 30 years. This increase in fires has implications for management of Soil Sub-Project Corrective Action Units (CAUs) for which the Department of Energy, National Nuclear Security Administration Nevada Site office (NNSA/NSO) has responsibility. A series of studies has been initiated at uncontaminated analog sites to better understand the possible impacts of erosion and transport by wind and water should contaminated soil sites burn over to understand technical and perceived risk they might pose to site workers and public receptors in communities around the NTS, TTR, and NTTR; and to develop recommendations for stabilization and restoration after a fire. The first of these studies was undertaken at the Jacob fire, a lightning-caused fire approximately 12 kilometers north of Hiko, Nevada, that burned approximately 200 ha between August 6-8, 2008, and is representative of a transition zone on the NTS between the Mojave and Great Basin Deserts, where the largest number of Soil Sub-Project CAUs/CASs are located.

Mechanistic Reactive Burn Modeling of Solid Explosives  

SciTech Connect

This report describes a computational framework for reactive burn modeling of solid explosives and the development of a test case where physical mechanisms represent RDX or RDX-based materials. The report is a sequel to LA-13794-MS, ''A Unifying Framework for Hot Spots and the Ignition of Energetic Materials,'' where we proposed a new approach to the building of a general purpose model that captures the essential features of the three primary origins of hot-spot formation: void collapse, shear banding, friction. The purpose of the present report is to describe the continuing task of coupling the unifying hot-spot model to hydrodynamic calculations to develop a mechanistic reactive burn model. The key components of the coupling include energy localization, the growth of hot spots, overall hot-spot behavior, and a phase-averaged mixture equation of state (EOS) in a Mie-Grueneisen form. The nucleation and growth of locally heated regions is modeled by a phenomenological treatment as well as a statistical model based on an exponential size distribution. The Mie-Grueneisen form of the EOS is one of many possible choices and is not a critical selection for implementing the model. In this report, model calculations are limited to proof-of-concept illustrations for shock loading. Results include (1) shock ignition and growth-to-detonation, (2) double shock ignition, and (3) quenching and reignition. A comparative study of Pop-plots is discussed based on the statistical model.

Modeling Deep Burn TRISO Particle Nuclear Fuel  

Science Conference Proceedings (OSTI)

Under the DOE Deep Burn program TRISO fuel is being investigated as a fuel form for consuming plutonium and minor actinides, and for greater efficiency in uranium utilization. The result will thus be to drive TRISO particulate fuel to very high burn-ups. In the current effort the various phenomena in the TRISO particle are being modeled using a variety of techniques. The chemical behavior is being treated utilizing thermochemical analysis to identify phase formation/transformation and chemical activities in the particle, including kernel migration. First principles calculations are being used to investigate the critical issue of fission product palladium attack on the SiC coating layer. Density functional theory is being used to understand fission product diffusion within the plutonia oxide kernel. Kinetic Monte Carlo techniques are shedding light on transport of fission products, most notably silver, through the carbon and SiC coating layers. The diffusion of fission products through an alternative coating layer, ZrC, is being assessed via DFT methods. Finally, a multiscale approach is being used to understand thermal transport, including the effect of radiation damage induced defects, in a model SiC material.

Impact of biomass burning on the atmosphere  

DOE Green Energy (OSTI)

Fire has played an important part in biogeochemical cycling throughout most of the history of our planet. Ice core studies have been very beneficial in paleoclimate studies and constraining the budgets of biogeochemical cycles through the past 160,000 years of the Vostok ice core. Although to date there has been no way of determining cause and effect, concentration of greenhouse gases directly correlates with temperature in ice core analyses. Recent ice core studies on Greenland have shown that significant climate change can be very rapid on the order of a decade. This chapter addresses the coupled evolution of our planet`s atmospheric composition and biomass burning. Special attention is paid to the chemical and climatic impacts of biomass burning on the atmosphere throughout the last century, specifically looking at the cycles of carbon, nitrogen, and sulfur. Information from ice core measurements may be useful in understanding the history of fire and its historic affect on the composition of the atmosphere and climate.

On the burning behavior of pulverized coal chars  

SciTech Connect

A model that predicts the physical changes that pulverized coal char particles undergo during combustion has been developed. In the model, a burning particle is divided into a number of concentric annular volume elements. The mass loss rate, specific surface area, and apparent density in each volume element depend upon the local particle conditions, which vary as a consequence of the adsorbed oxygen and gas-phase oxygen concentration gradients inside the particle. The model predicts the particle's burning rate, temperature, diameter, apparent density, and specific surface area as combustion proceeds, given ambient conditions and initial char properties. A six-step heterogeneous reaction mechanism is used to describe carbon reactivity to oxygen. A distributed activation energy approach is used to account for the variation in desorption energies of adsorbed O-atoms on the carbonaceous surface. Model calculations support the three burning zones established for the oxidation of pulverized coal chars. The model indicates two types of zone II behavior, however. Under weak zone II burning conditions, constant-diameter burning occurs up to 30% to 50% conversion before burning commences with reductions in both size and apparent density. Under strong zone II conditions, particles burn with reductions in both size and apparent density after an initial short period (conversion) of constant-diameter burning. Model predictions reveal that early in the oxidation process, there is mass loss at constant diameter under all zone II burning conditions. Such weak and strong burning behavior cannot be predicted with the commonly used power-law model for the mode of burning employing a single value for the burning mode parameter. Model calculations also reveal how specific surface area evolves when oxidation occurs in the zone II burning regime. Based on the calculated results, a surface area submodel that accounts for the effects of pore growth and coalescence during combustion under zone I conditions was modified to permit the characterization of the variations in specific surface area that occur during char conversion under zones II conditions. The modified surface area model is applicable to all burning regimes. Calculations also indicate that the particle's effectiveness factor varies during conversion under zone II burning conditions. With the adsorption/desorption mechanism employed, a near first-order Thiele modulus-effectiveness factor relationship is obeyed over the particle's lifetime. (author)

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.

Method and apparatus to measure the depth of skin burns  

DOE Patents (OSTI)

A new device for measuring the depth of surface tissue burns based on the rate at which the skin temperature responds to a sudden differential temperature stimulus. This technique can be performed without physical contact with the burned tissue. In one implementation, time-dependent surface temperature data is taken from subsequent frames of a video signal from an infrared-sensitive video camera. When a thermal transient is created, e.g., by turning off a heat lamp directed at the skin surface, the following time-dependent surface temperature data can be used to determine the skin burn depth. Imaging and non-imaging versions of this device can be implemented, thereby enabling laboratory-quality skin burn depth imagers for hospitals as well as hand-held skin burn depth sensors the size of a small pocket flashlight for field use and triage.

Turbulent burning rates of methane and methane-hydrogen mixtures  

Science Conference Proceedings (OSTI)

Methane and methane-hydrogen (10%, 20% and 50% hydrogen by volume) mixtures have been ignited in a fan stirred bomb in turbulence and filmed using high speed cine schlieren imaging. Measurements were performed at 0.1 MPa (absolute) and 360 K. A turbulent burning velocity was determined for a range of turbulence velocities and equivalence ratios. Experimental laminar burning velocities and Markstein numbers were also derived. For all fuels the turbulent burning velocity increased with turbulence velocity. The addition of hydrogen generally resulted in increased turbulent and laminar burning velocity and decreased Markstein number. Those flames that were less sensitive to stretch (lower Markstein number) burned faster under turbulent conditions, especially as the turbulence levels were increased, compared to stretch-sensitive (high Markstein number) flames.

Local Burn-Up Effects in the NBSR Fuel Element  

SciTech Connect

This study addresses the over-prediction of local power when the burn-up distribution in each half-element of the NBSR is assumed to be uniform. A single-element model was utilized to quantify the impact of axial and plate-wise burn-up on the power distribution within the NBSR fuel elements for both high-enriched uranium (HEU) and low-enriched uranium (LEU) fuel. To validate this approach, key parameters in the single-element model were compared to parameters from an equilibrium core model, including neutron energy spectrum, power distribution, and integral U-235 vector. The power distribution changes significantly when incorporating local burn-up effects and has lower power peaking relative to the uniform burn-up case. In the uniform burn-up case, the axial relative power peaking is over-predicted by as much as 59% in the HEU single-element and 46% in the LEU single-element with uniform burn-up. In the uniform burn-up case, the plate-wise power peaking is over-predicted by as much as 23% in the HEU single-element and 18% in the LEU single-element. The degree of over-prediction increases as a function of burn-up cycle, with the greatest over-prediction at the end of Cycle 8. The thermal flux peak is always in the mid-plane gap; this causes the local cumulative burn-up near the mid-plane gap to be significantly higher than the fuel element average. Uniform burn-up distribution throughout a half-element also causes a bias in fuel element reactivity worth, due primarily to the neutronic importance of the fissile inventory in the mid-plane gap region.

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.

Results of emissions testing while burning densified refuse derived fuel, Dordt College, Sioux Center, Iowa  

DOE Green Energy (OSTI)

Pacific Environmental Services, Inc. provided engineering and source testing services to the Council of Great Lake Governors to support their efforts in promoting the development and utilization of densified refuse derived fuels (d-RDF) and pelletized wastepaper fuels in small steam generating facilities. The emissions monitoring program was designed to provide a complete air emissions profile while burning various refuse derived fuels. The specific goal of this test program was to conduct air emissions tests at Dordt College located in Sioux Center, Iowa and to identify a relationship between fuel types and emission characteristics. The sampling protocol was carried out June 12 through June 20, 1989 on boiler {number sign}4. This unit had been previously modified to burn d-RDF. The boiler was not equipped with any type of air pollution control device so the emissions samples were collected from the boiler exhaust stack on the roof of the boilerhouse. The emissions that were sampled included: particulates; PM{sub 10} particulates; hydrochloric acid; dioxins; furans; polychlorinated biphenyls (PCB); metals and continuous monitors for CO, CO{sub 2}O{sub 2}SO{sub x}NO{sub x} and total hydrocarbons. Grab samples of the fuels were collected, composited and analyzed for heating value, moisture content, proximate and ultimate analysis, ash fusion temperature, bulk density and elemental ash analysis. Grab samples of the boiler ash were also collected and analyzed for total hydrocarbons total dioxins, total furans, total PCBs and heavy metals. 77 figs., 20 tabs.

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.

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.

Furniture wood wastes: Experimental property characterisation and burning tests  

Science Conference Proceedings (OSTI)

Referring to the industrial wood waste category (as dominant in the provincial district of Pesaro-Urbino, Marche Region, Italy), this paper deals with the experimental characterisation and the carrying out of non-controlled burning tests (at lab- and pilot-scale) for selected 'raw' and primarily 'engineered' ('composite') wood wastes. The property characterisation has primarily revealed the following aspects: potential influence on moisture content of local weather conditions at outdoor wood waste storage sites; generally, higher ash contents in 'engineered' wood wastes as compared with 'raw' wood wastes; and relatively high energy content values of 'engineered' wood wastes (ranging on the whole from 3675 to 5105 kcal kg{sup -1} for HHV, and from 3304 to 4634 kcal kg{sup -1} for LHV). The smoke qualitative analysis of non-controlled lab-scale burning tests has primarily revealed: the presence of specific organic compounds indicative of incomplete wood combustion; the presence exclusively in 'engineered' wood burning tests of pyrroles and amines, as well as the additional presence (as compared with 'raw' wood burning) of further phenolic and containing nitrogen compounds; and the potential environmental impact of incomplete industrial wood burning on the photochemical smog phenomenon. Finally, non-controlled pilot-scale burning tests have primarily given the following findings: emission presence of carbon monoxide indicative of incomplete wood combustion; higher nitrogen oxide emission values detected in 'engineered' wood burning tests as compared with 'raw' wood burning test; and considerable generation of the respirable PM{sub 1} fraction during incomplete industrial wood burning.

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.

Oil/gas separator for installation at burning wells  

DOE Patents (OSTI)

An oil/gas separator is disclosed that can be utilized to return the burning wells in Kuwait to production. Advantageously, a crane is used to install the separator at a safe distance from the well. The gas from the well is burned off at the site, and the oil is immediately pumped into Kuwait's oil gathering system. Diverters inside the separator prevent the oil jet coming out of the well from reaching the top vents where the gas is burned. The oil falls back down, and is pumped from an annular oil catcher at the bottom of the separator, or from the concrete cellar surrounding the well.

Can Consumers Escape the Market? Emancipatory Illuminations from Burning Man  

E-Print Network (OSTI)

This ethnography explores the emancipatory dynamics of the Burning Man project, a one-week-long antimarket event. Practices used at Burning Man to distance consumers from the market include discourses supporting communality and disparaging market logics, alternative exchange practices, and positioning consumption as self-expressive art. Findings reveal several communal practices that distance consumption from broader rhetorics of efficiency and rationality. Although Burning Man’s participants materially support the market, they successfully construct a temporary hypercommunity from which to practice divergent social logics. Escape from the market, if possible at all, must be conceived of as similarly temporary and local.

Spectral hole burning for stopping light  

E-Print Network (OSTI)

We propose a novel protocol for storage and retrieval of photon wave packets in a $\\Lambda$-type atomic medium. This protocol derives from spectral hole burning and takes advantages of the specific properties of solid state systems at low temperature, such as rare earth ion doped crystals. The signal pulse is tuned to the center of the hole that has been burnt previously within the inhomogeneously broadened absorption band. The group velocity is strongly reduced, being proportional to the hole width. This way the optically carried information and energy is carried over to the off-resonance optical dipoles. Storage and retrieval are performed by conversion to and from ground state Raman coherence by using brief $\\pi$-pulses. The protocol exhibits some resemblance with the well known electromagnetically induced transparency process. It also presents distinctive features such as the absence of coupling beam. In this paper we detail the various steps of the protocol, summarize the critical parameters and theoretically examine the recovery efficiency.

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).

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.

On burning regimes and long duration X-ray bursts  

E-Print Network (OSTI)

Hydrogen and helium accreted onto a neutron star undergo thermonuclear burning. Explosive burning is observed as a type I X-ray burst. We describe the different burning regimes and focus on some of the current inconsistencies between theory and observations. Of special interest are the rare kinds of X-ray bursts such as carbon-fueled superbursts and helium-fueled intermediately long X-ray bursts. These bursts are thought to originate deeper in the neutron star envelope, such that they are probes of the thermal properties of the crust. We investigate the possibility of observing superbursts with the wide-field instruments INTEGRAL-ISGRI and Swift-BAT. We find that only the brightest bursts are detectable.

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.

Theory of Antineutrino Monitoring of Burning MOX Plutonium Fuels

This letter presents the physics and feasibility of reactor antineutrino monitoring to verify the burnup of plutonium loaded in the reactor as a Mixed Oxide (MOX) fuel. It examines the magnitude and temporal variation in the antineutrino signals expected for different MOX fuels, for the purposes of nuclear accountability and safeguards. The antineutrino signals from reactor-grade and weapons-grade MOX are shown to be distinct from those from burning low enriched uranium. Thus, antineutrino monitoring could be used to verify the destruction of plutonium in reactors, though verifying the grade of the plutonium being burned is found to be more challenging.

Open Questions in Stellar Helium Burning Addressed With Real Photons  

E-Print Network (OSTI)

The outcome of helium burning is the formation of the two elements, carbon and oxygen. The ratio of carbon to oxygen at the end of helium burning is crucial for understanding the final fate of a progenitor star and the nucleosynthesis of heavy elements in Type II supernova, with oxygen rich star predicted to collapse to a black hole, and a carbon rich star to a neutron star. Type Ia supernovae (SNeIa) are used as standard candles for measuring cosmological distances with the use of an empirical light curve-luminosity stretching factor. It is essential to understand helium burning that yields the carbon/oxygen white dwarf and thus the initial stage of SNeIa. Since the triple alpha-particle capture reaction, $^{8}Be(\\alpha,\\gamma)^{12}C$, the first burning stage in helium burning, is well understood, one must extract the cross section of the $^{12}C(\\alpha,\\gamma)^{16}O$ reaction at the Gamow window (300 keV) with high accuracy of approximately 10% or better. This goal has not been achieved despite repeated strong statements that appeared in the literature. In particular constraint from the beta-delayed alpha-particle emission of $^{16}N$ were shown to not sufficiently restrict the p-wave cross section factor; e.g. a low value of $S_{E1}(300)$ can not be ruled out. Measurements at low energies, are thus mandatory for determining the elusive cross section factor for the $^{12}C(\\alpha,\\gamma)^{16}O$ reaction. We are constructing a Time Projection Chamber (TPC) for use with high intensity photon beams extracted from the HI$\\gamma$S/TUNL facility at Duke University to study the $^{16}O(\\gamma,\\alpha)^{12}C$ reaction, and thus the direct reaction at energies as low as 0.7 MeV. This work is in progress.
