The seasonal cycle dependence of temperature fluctuations in the atmosphere  

E-Print Network (OSTI)

The correlation statistics of meteorological fields have been of interest in weather forecasting for many years and are also of interest in climate studies. A better understanding of the seasonal variation of correlation statistics can be used to determine how the seasonal cycle of temperature fluctuations should be simulated in noise-forced energy balance models. It is shown that the length scale does have a seasonal dependence and will have to be handled through the seasonal modulation of other coefficients in noise-forced energy balance models. The temperature field variance and spatial correlation fluctuations exhibit seasonality with fluctuation amplitudes larger in the winter hemisphere and over land masses. Another factor contributing to seasonal differences is the larger solar heating gradient in the winter. 40 years of monthly mean surface data and 25 years of monthly mean 700mb and 500mb data is averaged over the seasons. The spatial correlation of four northern hemisphere midlatitude test sites, two ocean sites and two land sites, at the surface, at 700mb and at 500mb is examined for the winter, spring, summer and fall. The correlations between the different vertical levels and the variance of each level is also presented and examined.

Room Temperature Control During Season Switchover with Single Duct Variable Air Volume System Without Reheat  

E-Print Network (OSTI)

The Langford “A” building houses the College of Architecture on TAMU campus. There are ten singleduct variable air volume (VAV) air-handling units (AHUs) without reheat serving the building. The local pneumatic thermostats modulate the dampers of VAV boxes to maintain room temperature at their setpoints. The thermostat action is switched from direct acting (DA) to reverse acting (RA) when the season changes from fall to winter and vice versa from winter to spring, based on the out side air temperature, when season changes. This results in various parts of the building ether too cold or too hot during the season change. This paper presents that the thermostat action will be switched according to cooling loads or discharge air temperature, instead of outside air temperature. For the interior zone, thermostat action does not need to be switched at all. The comfort is improved and savings is achieved by the new control scheme. Because some air-handling units (AHUs) serve both interior and exterior zones, this system never worked as intended. The system must be modified to have zone reheat and the AHUs discharge air temperature is set below dew point for humidity control.

Effect of seasonal variations of ambient temperatures on the performance of low temperature power cycles  

DOE Green Energy (OSTI)

Studies on the performance of the binary fluid system was carried out in two stages. In the first stage the ideal case was analyzed as to the effects of sinusoidal variations of the heat rejection temperature on the ideal work available from a steady flow of a geothermal brine delivered to a power plant under constant wellhead conditions. In the second stage an approximate method for analyzing actual cases was introduced. Results indicate that sink temperature fluctuations have a drastic effect on the output of low-temperature power cycles. The severe fluctuations in the output are likely to have a strong influence on the design and optimization studies of such cycles. The impact of this on the economies of electric power generation from geothermal resources should be carefully assessed before choosing among possible energy-conversion systems. (JGB)

Observations of seasonal variations in atmospheric greenhouse trapping and its enhancement at high sea surface temperature  

SciTech Connect

The correlation between observed values of atmospheric greenhouse trapping and sea surface temperature is found to vary seasonally. Atmospheric greenhouse trapping is defined here as the difference between infrared emissions from the earth's surface and infrared emissions from the top of the atmosphere through cloudless skies. Infrared surface emissions are calculated from known sea surface temperatures; emissions from the top of the atmosphere are taken from direct satellite measurements. Atmospheric greenhouse trapping at the same sea surface temperature is greater in the winter than in the summer over temperate oceans. In subtropical latitudes, the opposite is true. At surface temperatures above approximately 298 K, atmospheric greenhouse trapping is found to increase even more rapidly from regions of lower sea surface temperature to regions of higher surface temperature than infrared surface emissions. The causes for this [open quotes]super[close quotes] greenhouse effect are explored, and four processes are found to contribute. Water vapor continuum absorption and thermodynamically controlled increases in water vapor concentration at constant relative humidity with increasing atmospheric temperature make significant contributions, but do not explain the entire super greenhouse effect. To explain the observations of atmospheric greenhouse trapping, the upper and middle troposphere, must be increasingly moist over the warmest sea surface temperatures, while the atmospheric temperature profile becomes increasingly unstable. Regions with these high sea surface temperatures are also increasingly subject to deep convection, which suggests that convection moistens the upper and middle troposphere in regions of convective activity relative to nonconvective regions, resulting in the super greenhouse effect. Dynamic processes, along with local thermodynamic processes, are required to explain the observed super greenhouse effect. 30 refs., 3 figs., 2 tabs.

Seasonal variations of the clear-sky greenhouse effect: The role of changes in atmospheric temperatures and humidities  

SciTech Connect

This paper presents an analysis of the factors which control the seasonal variations of the clear-sky greenhouse effect, based on satellite observations and radiative transfer simulations. The satellite observations include the radiation budget at the top of the atmosphere from the Earth Radiation Budget Experiment and the total column moisture content derived from the Special Sensor Microwave/Imager. The simulations were performed with the SAMSON system described in an earlier paper, using atmospheric temperatures and humidities from operational analyses produced by the European Centre for Medium Range Weather Forecasts. At low latitudes, the magnitude of the clear-sky greenhouse effect is dominated by the strong thermodynamic link between the total column moisture content of the atmosphere and sea surface temperatures, with minimal seasonal variations. In contrast, at middle to high latitudes there are strong seasonal variations, the clear-sky greenhouse effect being largest in winter and smallest in summer. These variations cannot be explained by the seasonal cycle in the total column moisture content, as this is largest in summer and smallest in winter. The variations are controlled instead by the seasonal changes in atmospheric temperatures. The colder atmosphere in winter enhances the temperature differential between the atmosphere and the sea surface, leading to a larger greenhouse effect despite the lower moisture contents. The magnitude of the clear-sky greenhouse effect is thus controlled by atmospheric humidity at low latitudes, but by atmospheric temperature at middle and high latitudes. These controls are illustrated by results from sensitivity experiments with SAMSON and are interpreted in terms of a simple model.

Influence of the vertical structure of the atmosphere on the seasonal variation of precipitable water and greenhouse effect  

SciTech Connect

By using satellite observations and European Centre for Medium Range Weather Forecasts (ECMWF) analyses, we study the seasonal variations of the precipitable water and the greenhouse effect, defined as the normalized difference between the longwave flux emitted at the surface and that emergent at the top of the atmosphere. Results show a strong systematic influence of the vertical structure of the atmosphere on geographical and seasonal variations of both precipitable water and greenhouse effect. Over ocean, in middle and high latitudes, the seasonal variation of the mean temperature lapse rate in the troposphere leads to large seasonal phase lags between greenhouse effect and precipitable water. By contrast, the seasonal variation of the clear-sky greenhouse effect over tropical oceans is mainly driven by the total atmospheric transmittance and thus by precipitable water variations. Over land, the seasonal variations of the tropospheric lapse rate acts to amplify the radiative impact of water vapor changes, giving a strong seasonal variation of the greenhouse effect. Over tropical land regions, monsoon activity generates a seasonal phase lag between surface temperature and relative humidity variations that gives a seasonal lag of about 2 months between the surface temperature and the clear-sky greenhouse effect. Generally, the cloudiness amplifies clear-sky tendencies. Finally, as an illustration, obtained results are used to evaluate the general circulation model of the Laboratoire de Meteorologie Dynamique.

Influence of negative-U centers on the temperature dependence of the carrier concentration in the normal HTSC phase  

SciTech Connect

The temperature dependence of the hole concentration in high-temperature superconductors is considered in terms of the model of negative-U centers. It is shown that this dependence can be nonmonotonic due to the interaction of electron subsystems from the valence band with negative-U centers and the conditions necessary for this have been established. The results obtained are compared with experimental data on the Hall coefficient in cuprates.

Optimal design of seasonal storage for 100% solar space heating in buildings  

DOE Green Energy (OSTI)

An analysis is presented of seasonal solar systems that contain water as the sensible heat storage medium. A concise model is developed under the assumption of a fully mixed, uniform temperature, storage tank that permits efficient simulation of long-term (multi-day) system performance over the course of the year. The approach explicitly neglects the effects of short-term (sub-daily) fluctuations in insolation and load, effects that will be extremely small for seasonal solar systems. This approach is useful for examining the major design tradeoffs of concern here. The application considered is winter space heating. The thermal performance of seasonal solar systems that are designed to supply 100% of load without any backup is solved for, under ''reference year'' monthly normal ground temperature and insolation conditions. Unit break-even costs of seasonal storage are estimated by comparing the capital and fuel costs of conventional heating technologies against those of a seasonal solar system. A rough comparison between the alternatives for more severe winters was made by examining statistical variations in winter season conditions over the past several decades. (MHR)

Delayed Seasonal Cycle and African Monsoon in a Warmer Climate  

E-Print Network (OSTI)

Increasing greenhouse gases will change many aspects of the Earth's climate, from its annual mean to the frequency of extremes such as heat waves and droughts. Here we report that the current generation of climate models predicts a delay in the seasonal cycle of global rainfall and ocean temperature in response to increasing greenhouse gases, with important implications for the regional monsoons. In particular, the rainy season of the semi-arid African Sahel is projected to start later and become shorter: an undesirable change for local rainfed agriculture and pastoralism. Previous work has highlighted the uncertainty in this region's response to anthropogenic global warming: summer rainfall is predicted either to decrease or increase by up to 30% depending which model is used. The robust agreement across models on the seasonal distribution of rainfall changes signifies that the onset date and length of the rainy season should be more predictable than annual mean anomalies.

2008 Draft Season Summary.  

DOE Green Energy (OSTI)

This report describes investigations into predation by piscivorous colonial waterbirds on juvenile salmonids (Oncorhynchus spp.) from throughout the Columbia River basin during 2008. East Sand Island in the Columbia River estuary again supported the largest known breeding colony of Caspian terns (Hydroprogne caspia) in the world (approximately 10,700 breeding pairs) and the largest breeding colony of double-crested cormorants (Phalacrocorax auritus) in western North America (approximately 10,950 breeding pairs). The Caspian tern colony increased from 2007, but not significantly so, while the double-crested cormorant colony experienced a significant decline (20%) from 2007. Average cormorant nesting success in 2008, however, was down only slightly from 2007, suggesting that food supply during the 2008 nesting season was not the principal cause of the decline in cormorant colony size. Total consumption of juvenile salmonids by East Sand Island Caspian terns in 2008 was approximately 6.7 million smolts (95% c.i. = 5.8-7.5 million). Caspian terns nesting on East Sand Island continued to rely primarily on marine forage fishes as a food supply. Based on smolt PIT tag recoveries on the East Sand Island Caspian tern colony, predation rates were highest on steelhead in 2008; minimum predation rates on steelhead smolts detected passing Bonneville Dam averaged 8.3% for wild smolts and 10.7% for hatchery-raised smolts. In 2007, total smolt consumption by East Sand Island double-crested cormorants was about 9.2 million juvenile salmonids (95% c.i. = 4.4-14.0 million), similar to or greater than that of East Sand Island Caspian terns during that year (5.5 million juvenile salmonids; 95% c.i. = 4.8-6.2 million). The numbers of smolt PIT tags recovered on the cormorant colony in 2008 were roughly proportional to the relative availability of PIT-tagged salmonids released in the Basin, suggesting that cormorant predation on salmonid smolts in the estuary was less selective than tern predation. Cormorant predation rates in excess of 30%, however, were observed for some groups of hatchery-reared fall Chinook salmon released downstream of Bonneville Dam. Implementation of the federal plan 'Caspian Tern Management to Reduce Predation of Juvenile Salmonids in the Columbia River Estuary' was initiated in 2008 with construction by the Corps of Engineers of two alternative colony sites for Caspian terns in interior Oregon: a 1-acre island on Crump Lake in the Warner Valley and a 1-acre island on Fern Ridge Reservoir near Eugene. We deployed Caspian tern social attraction (decoys and sound systems) on these two islands and monitored for Caspian tern nesting. Caspian terns quickly colonized the Crump Lake tern island; about 430 pairs nested there, including 5 terns that had been banded at the East Sand Island colony in the Columbia River estuary, over 500 km to the northwest. No Caspian terns nested at the Fern Ridge tern island in 2008, but up to 9 Caspian terns were recorded roosting on the island after the nesting season. There were two breeding colonies of Caspian terns on the mid-Columbia River in 2008: (1) about 388 pairs nested at the historical colony on Crescent Island in the McNary Pool and (2) about 100 pairs nested at a relatively new colony site on Rock Island in the John Day Pool. Nesting success at the Crescent Island tern colony was only 0.28 young fledged per breeding pair, the lowest nesting success recorded at that colony since monitoring began in 2000, while only three fledglings were raised at the Rock Island tern colony. The diet of Crescent Island Caspian terns consisted of 68% salmonid smolts; total smolt consumption was estimated at 330,000. Since 2004, total smolt consumption by Crescent Island terns has declined by 34%, due mostly to a decline in colony size, while steelhead consumption has increased 10% during this same period. In 2008, approximately 64,000 steelhead smolts were consumed by Caspian terns nesting at Crescent Island. Based on smolt PIT tag recoveries on the Crescent Island Caspian tern colony, the average

Oxygen isotope records of carboniferous seasonality on the Russian platform  

E-Print Network (OSTI)

Seven isotopic and eight trace element (TE) profiles across shell growth lines are presented, based on over 1000 stable isotope and electron microprobe analyses on six brachiopod shells (Gigantoproductus), to quantify seasonal temperature change in the early Carboniferous Moscow Basin. Evidence for good shell preservation is the retention of original prismatic shell microstructure and the general lack of cathodoluminescence in shell interiors. Only shell edges show luminescent calcite. Other evidence for good preservation of the six shells includes undetectable Fe and Mn contents in mid-shell areas compared with high Fe and Mn contents at shell edges, different trends of 813C and 8180 between shell edges and mid-shell areas, and distinct growth lines in the prismatic secondary layers. Forty-one 8180 cycles are found in six profiles, with amplitudes ranging from 0.2%c to 2.7%c. The majority of cycles vary in amplitude from-0.4%0 to-1.2%0, with a mean of-0.8%o, representing annual temperature change of 2'C to 6'C in the early Carboniferous tropical zone. This seasonality is compatible with the-3'C modern tropic annual temperature range, and contrasts significantly with the conclusion based on growth rings of fossil woods that there was no significant seasonal variations in the tropics during the early Carboniferous. For carbon isotopes, temperature-depended metabolic activity appears to be the main factor controlling 81 3C variations- The numbers of cycles recorded in 180 profiles, 13C profiles, Mg profiles, and growth lines are 41, 41, 40, and 37 respectively. The similarity in cyclicity of these four different measures argues that they are all controlled by seasonal-dependent factors, such as temperature and metabolic rate. Except for number of cycles, there are no significant controlled by temperature, TE contents may be controlled by metabolic rates and perhaps the reproductive cycle.

U.S. Energy Information Administration (EIA) Indexed Site

Active hurricane season expected to shut-in higher amount of Active hurricane season expected to shut-in higher amount of oil and natural gas production An above-normal 2013 hurricane season is expected to cause a median production loss of about 19 million barrels of U.S. crude oil and 46 billion cubic feet of natural gas production in the Gulf of Mexico, according to the new forecast from the U.S. Energy Information Administration. That's about one-third more than the amount of oil and gas production knocked offline during last year's hurricane season. Government weather forecasts predict 13 to 20 named storms will form between June and the end of November, with 7 to 11 of those turning into hurricanes.

Study of Applications of Solar Heating Systems with Seasonal Storage in China  

E-Print Network (OSTI)

In most northern parts of China, it is cold in winter and needs space heating in winter. This paper studies applications of solar heating systems with seasonal storage in China. A typical residential district was selected, and a solar heating system with seasonal storage was designed and simulated based on various conditions. The results indicate that 1) for many places of China, solar systems with seasonal storage can save conventional energy and can be competitive with gas-fired boiler heating; 2) when the ratio of volume of seasonal storage tank to collector areas is 3~5, the system performance is optimal for many places in China; 3) the obtained solar heat is mainly dependent on the solar irradiance, length of heating period and ambient temperature. Solar heating with seasonal storage in chilly places may also get good performance.

Science Conference Proceedings (OSTI)

IR and Raman spectra of Ca{sub 2}MgSi{sub 2}O{sub 7}, Ca{sub 2}ZnSi{sub 2}O{sub 7} and Sr{sub 2}MgSi{sub 2}O{sub 7} oriented single crystals and powders have been measured. The temperature dependence of phonons has been established in the 4-650 K range. Discussion of the results has been performed on the basis of factor group approach for the tetragonal P4-bar 2{sub 1}m (D{sub 2d}{sup 3}) space group with Z=2. The assignment of the bands observed to the internal and external modes has been made on their polarization behaviour, phonon energy calculations and literature data. The evidences of the LO-TO splitting and commensurate (C) to incommensurate (IC) as well as incommensurate (IC) to normal (N) phase transitions have been found. As a representative example, the results obtained for the spontaneous Raman scattering have also been used in the discussion of the stimulated Raman spectra of Ca{sub 2}ZnSi{sub 2}O{sub 7}. - Graphical abstract: Raman and IR spectra of Ca{sub 2}MgSi{sub 2}O{sub 7}, Ca{sub 2}ZnSi{sub 2}O{sub 7}, Sr{sub 2}MgSi{sub 2}O{sub 7} have been measured. The temperature dependence of phonons has been established in the 4-650 K range. The evidences of the LO-TO splitting and commensurate (C) to incommensurate (IC) as well as incommensurate (IC) to normal (N) phase transitions have been found. Highlights: Black-Right-Pointing-Pointer Polarized IR and Raman spectra of pyrosilicates single crystals have been studied.

German central solar heating plants with seasonal heat storage  

Science Conference Proceedings (OSTI)

Central solar heating plants contribute to the reduction of CO{sub 2}-emissions and global warming. The combination of central solar heating plants with seasonal heat storage enables high solar fractions of 50% and more. Several pilot central solar heating plants with seasonal heat storage (CSHPSS) built in Germany since 1996 have proven the appropriate operation of these systems and confirmed the high solar fractions. Four different types of seasonal thermal energy stores have been developed, tested and monitored under realistic operation conditions: Hot-water thermal energy store (e.g. in Friedrichshafen), gravel-water thermal energy store (e.g. in Steinfurt-Borghorst), borehole thermal energy store (in Neckarsulm) and aquifer thermal energy store (in Rostock). In this paper, measured heat balances of several German CSHPSS are presented. The different types of thermal energy stores and the affiliated central solar heating plants and district heating systems are described. Their operational characteristics are compared using measured data gained from an extensive monitoring program. Thus long-term operational experiences such as the influence of net return temperatures are shown. (author)

Propane: A Mid-heating Season Assessment  

Gasoline and Diesel Fuel Update (EIA)

9, 2001 9, 2001 Propane - A Mid-Heating Season Assessment by David Hinton and Alice Lippert, Petroleum Division, Office of Oil and Gas, Energy Information Administration In early October 2000, the Energy Information Administration (EIA) forecast that heating fuel markets would be expected to start the season with much higher prices and lower inventories than in recent years. While this assessment was true for both the heating oil and natural gas markets, propane markets actually began the season with adequate supplies but with high prices. Since EIA's forecast, propane inventories have plunged nearly 20 million barrels from their peak during the first half of the 2000-01 heating season while propane prices have continued to soar even higher than expected during this same period.

Solar and seasonal dependence of ion frictional heating  

E-Print Network (OSTI)

Abstract. Ion frictional heating constitutes one of the principal mechanisms whereby energy, originating in the solar wind, is deposited into the Earth's ionosphere and ultimately the neutral atmosphere. Common programme observations by the EISCAT UHF radar system, spanning the years 1984 to 1995, provide the basis for a comprehensive statistical study of ion frictional heating, results of which are documented in this and a previous paper by the authors. In the present work, the authors demonstrate the solar and seasonal dependence of the universal time distribution of frictional heating, and explain these results with reference to corresponding dependences of the ion velocity. Although EISCAT observes a signi®cant increase in the occurrence of enhanced ion velocities associated with increased solar activity, the latter characterised according to the prevailing 10.7 cm solar ¯ux, this is not re¯ected to such an extent in the occurrence of frictional heating. It is suggested that this is a consequence of the decreased neutral atmosphere response times associated with active solar conditions, resulting from the higher ionospheric plasma densities present. Seasonal e€ects on the diurnal distribution of ion frictional heating are well explained by corresponding variations in ionospheric convection, the latter principally a result of geometrical factors. It is noted that, over the entire dataset, the variations in the unperturbed F-region ion temperature, required to implement the identi®cation criterion for ion heating, are highly correlated with model values of thermospheric temperature.

Response of California temperature to regional anthropogenic aerosol  

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

Response of California temperature to regional anthropogenic aerosol Response of California temperature to regional anthropogenic aerosol changes Title Response of California temperature to regional anthropogenic aerosol changes Publication Type Journal Article Year of Publication 2008 Authors Novakov, Tihomir, Thomas W. Kirchstetter, Surabi Menon, and Jeffery Aguiar Journal Geophysical Research Letters Volume 35 Issue 19 Abstract In this paper, we compare constructed records of concentrations of black carbon (BC) - an indicator of anthropogenic aerosols - with observed surface temperature trends in California. Annual average BC concentrations in major air basins in California significantly decreased after about 1990, coincident with an observed statewide surface temperature increase. Seasonal aerosol concentration trends are consistent with observed seasonal temperature trends. These data suggest that the reduction in anthropogenic aerosol concentrations contributed to the observed surface temperature increase. Conversely, high aerosol concentrations may lower surface temperature and partially offset the temperature increase of greenhouse gases.

Aquifer thermal energy storage costs with a seasonal heat source.  

SciTech Connect

The cost of energy supplied by an aquifer thermal energy storage (ATES) system from a seasonal heat source was investigated. This investigation considers only the storage of energy from a seasonal heat source. Cost estimates are based upon the assumption that all of the energy is stored in the aquifer before delivery to the end user. Costs were estimated for point demand, residential development, and multidistrict city ATES systems using the computer code AQUASTOR which was developed specifically for the economic analysis of ATES systems. In this analysis the cost effect of varying a wide range of technical and economic parameters was examined. Those parameters exhibiting a substantial influence on ATES costs were: cost of purchased thermal energy; cost of capital; source temperature; system size; transmission distance; and aquifer efficiency. ATES-delivered energy costs are compared with the costs of hot water heated by using electric power or fuel-oils. ATES costs are shown as a function of purchased thermal energy. Both the potentially low delivered energy costs available from an ATES system and its strong cost dependence on the cost of purchased thermal energy are shown. Cost components for point demand and multi-district city ATES systems are shown. Capital and thermal energy costs dominate. Capital costs, as a percentage of total costs, increase for the multi-district city due to the addition of a large distribution system. The proportion of total cost attributable to thermal energy would change dramatically if the cost of purchased thermal energy were varied. It is concluded that ATES-delivered energy can be cost competitive with conventional energy sources under a number of economic and technical conditions. This investigation reports the cost of ATES under a wide range of assumptions concerning parameters important to ATES economics. (LCL)

Normalization method for video images  

DOE Patents (OSTI)

The present invention relates to a method and apparatus for automatically and adaptively normalizing analog signals representative of video images in object detection systems. Such normalization maximizes the average information content of the video images and, thereby, provides optimal digitized images for object detection and identification. The present invention manipulates two system control signals -- gain control signal and offset control signal -- to convert an analog image signal into a transformed analog image signal, such that the corresponding digitized image contains the maximum amount of information achievable with a conventional object detection system. In some embodiments of the present invention, information content is measured using parameters selected from image entropy, image mean, and image variance.

This paper is devoted to the mathematical study of some divergences based on the mutual information well-suited to categorical random vectors. These divergences are generalizations of the“entropy distance”and“information distance”. Their main characteristic is that they combine a complexity term and the mutual information. We then introduce the notion of (normalized) informationbased divergence, propose several examples and discuss their mathematical properties.

Seasonal and multiannual roost use by Rafinesque's Big-eared Bats in the Coastal Plain of South Carolina.  

Science Conference Proceedings (OSTI)

Little is known about factors affecting year-round use of roosts by Rafinesque's big-eared bats (Corynorhinus rafinesquii) or the long-term fidelity of this species to anthropogenic or natural roosts. The objectives of this study were to test whether seasonal use of roosts by Rafinesque's big-eared bats varied with roost type and environmental conditions within and among seasons and to document multiannual use of natural and anthropogenic structures by this species. We inspected 4 bridges, 1 building, and 59 tree roosts possessing basal cavity openings; roosts were inspected at least once per week from May through October in every year from 2005 through 2008 and once a month from November through April in every year from 2005 through 2009. We found that use of anthropogenic roosts was significantly greater than the use of tree roosts in summer but that the use of structure types did not differ in other seasons. There was significant seasonal variation in use of anthropogenic and tree roosts. Anthropogenic roost use was higher in summer than in all other seasons. There was no significant difference in tree use among spring, summer, and fall, but use in winter was significantly lower in 2 years of the study. Overall use of anthropogenic and tree roosts was positively related to minimum temperature, but the relationship between use of roosts and minimum temperature varied among seasons. Bats showed multiannual fidelity ({ge} 4 years) to all anthropogenic roosts and to some tree roosts, but fidelity of bats to anthropogenic roosts was greater and more consistent than to tree roosts. Our data indicate that Rafinesque's big-eared bats responded differently to environmental conditions among seasons; thus, a variety of structure types and characteristics are necessary for conservation of these bats. We suggest long-term protection of roost structures of all types is necessary for conservation of Rafinesque's big-eared bats in the southeast Coastal Plain.

Seasonal variability of wind electric potential in the United States  

DOE Green Energy (OSTI)

Seasonal wind electric potential has been estimated for the contiguous United States based on the methods previously used to estimate the annual average wind electric potential. National maps show estimates of the seasonal wind electric potential averaged over the state as a whole, and gridded maps show the distribution of the seasonal wind electric potential within a state. The seasons of winter and spring have highest wind electric potential for most windy areas in the United States. Summer is the season with the least potential for most of the contiguous United States. Wind electric potential patterns in autumn generally resemble the annual average potential map. Excellent matches between seasonal wind electric potential and electric energy use occur during winter for the northern parts of the nation. California has a good match between summer wind potential and electric use.

Radiant Barrier Performance during the Heating Season  

E-Print Network (OSTI)

Results of winter experiments conducted in Central Texas are presented. The experiments were side-by-side tests using two identical 144 ft2 houses which responded similarly to weather variations prior to any retrofits. Two radiant barrier orientations were tested, horizontal barrier and barrier against the rafters, in vented and non-vented attics. The results compiled in this paper are for attics with R-19 fiberglass insulation. The data showed that radiant barriers were still effective during the winter season. During a typical day radiant barriers prevented approximately 9-17 percent of the indoor heat from escaping into the attic. No significant difference in moisture accumulation was detected in the attic with the radiant barrier.

Normalized Compression Distance of Multiples  

E-Print Network (OSTI)

Normalized compression distance (NCD) is a parameter-free similarity measure based on compression. The NCD between pairs of objects is not sufficient for all applications. We propose an NCD of finite multisets (multiples) of objacts that is metric and is better for many applications. Previously, attempts to obtain such an NCD failed. We use the theoretical notion of Kolmogorov complexity that for practical purposes is approximated from above by the length of the compressed version of the file involved, using a real-world compression program. We applied the new NCD for multiples to retinal progenitor cell questions that were earlier treated with the pairwise NCD. Here we get significantly better results. We also applied the NCD for multiples to synthetic time sequence data. The preliminary results are as good as nearest neighbor Euclidean classifier.

Neogene Low-latitude Seasonal Environmental Variations: Stable Isotopic and Trace Elemental Records in Mollusks from the Florida Platform and the Central American Isthmus  

E-Print Network (OSTI)

This Ph.D. dissertation integrates stable isotope and trace element geochemistry in modern and fossil gastropod shells to study low-latitude marine paleoenvironments. First, stable isotopes (delta18O and delta13C) and Sr/Ca ratios are used to examine low-latitude temperature and salinity variations recorded in Plio-Pleistocene (3.5-1.6 Ma) fossils from western Florida during periods of high-latitude warming and "global" cooling. The middle Pliocene Pinecrest Beds (Units 7 and 4) and the overlaying Plio-Pleistocene Caloosahatchee Formation generate significantly different delta18O-derived paleotemperatures but identical Sr/Ca ratios. High delta18O values, together with low delta13C values and brackish fauna, indicate that Unit 4 was deposited in a lagoonal environment similar to modern Florida Bay. In contrast, relatively low delta18O and high delta13C values in Unit 7 and Caloosahatchee Formation represent deposition in an open-marine environment. The observed Unit 7 and Caloosahatchee paleotemperatures are inconsistent with middle Pliocene warming event, but consistent with the Plio-Pleistocene cooling trend. To quantify modern upwelling and freshening signals and contrast these signals between the tropical eastern Pacific (TEP) and southwestern Caribbean (SWC), methodologies are developed for reconstructing seasonal upwelling and freshening patterns from modern tropical gastropod shells from Panama using: 1) paired oxygen and carbon isotopic profiles and delta18O-delta13C (delta-delta) correlations, and 2) deviation from baseline delta18O values that represent conditions free of seasonal upwelling or freshening influences. Shell delta18O values normalized to the baseline faithfully record modern conditions of little or no upwelling in SWC and Gulf of Chiriqui, and strong upwelling in the Gulf of Panama, as well as strong freshwater input in most areas. The baseline and delta-delta methods are applied to identify and quantify changes in upwelling and freshening in the Neogene TEP and SWC seawaters associated with the final closure of Central American Isthmus. The records reveal significant upwelling in late Miocene SWC and mid Pliocene TEP waters, strong freshening in SWC waters from 5.7-2.2 Ma, and minimal seasonal upwelling and/or freshening variations in Plio-Pleistocene SWC waters. The reconstructed paleotemperatures agree with the global cooling trend through the late Miocene, but lack evidence for middle Pliocene warming or late Neogene global cooling.

Coccidioidomycosis Incidence in Arizona Predicted by Seasonal Precipitation  

E-Print Network (OSTI)

The environmental mechanisms that determine the inter-annual and seasonal variability in incidence of coccidioidomycosis are unclear. In this study, we use Arizona coccidioidomycosis case data for 1995–2006 to generate a timeseries of monthly estimates of exposure rates in Maricopa County, AZ and Pima County, AZ. We reveal a seasonal autocorrelation structure for exposure rates in both Maricopa County and Pima County which indicates that exposure rates are strongly related from the fall to the spring. An abrupt end to this autocorrelation relationship occurs near the the onset of the summer precipitation season and increasing exposure rates related to the subsequent season. The identification of the autocorrelation structure enabled us to construct a ‘‘primary’ ’ exposure season that spans August-March and a ‘‘secondary’ ’ season that spans April– June which are then used in subsequent analyses. We show that October–December precipitation is positively associated with rates of exposure for the primary exposure season in both Maricopa County (R = 0.72, p = 0.012) and Pima County (R = 0.69, p = 0.019). In addition, exposure rates during the primary exposure seasons are negatively associated with concurrent precipitation in Maricopa (R = 20.79, p = 0.004) and Pima (R = 20.64, p = 0.019), possibly due to reduced spore dispersion. These associations enabled the generation of models to estimate exposure rates for the primary exposure season. The models explain 69 % (p = 0.009) and 54 % (p = 0.045) of the variance in the study period for Maricopa and Pima counties, respectively. We did not find any significant predictors for exposure rates during the secondary season. This study

Fall: Energy Saving Changes with the Season | Department of Energy  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

Fall: Energy Saving Changes with the Season Fall: Energy Saving Changes with the Season Fall: Energy Saving Changes with the Season October 18, 2011 - 6:42am Addthis Andrea Spikes Communicator at DOE's National Renewable Energy Laboratory I'm sure you've noticed the change in seasons by now. Fall brings cooler weather, and with it my thoughts turn to warm things like putting blankets on the couch, enjoying my fireplace, and adjusting my thermostat (as little as possible, of course). One thing we did over the weekend is we insulated our water heater. Depending on how efficient your water heater tank is, adding insulation can reduce standby heat losses by 25%-45% and save you around 4%-9% in water heating costs. Since water heating contributes an average of 18% to the typical home utility bill, it's definitely worth it to add insulation!

State of Maine residential heating oil survey: 1994--1995 Season summary  

Science Conference Proceedings (OSTI)

The 1994--95 heating season approached with more attention to petroleum products than experienced in some time. This year, however, the focus was on transportation fuels with the introduction of reformulated gasolines scheduled for the first of 1995. Last year transportation fuels had been in the spotlight in the Northeast as well, for the ills experienced with a new winter mix for diesel fuel. Would RFG have the same dubious entrance as diesel`s winter mix? Would RFG implementation work and what effect would the change in stocks have on the refineries? With worries related to transportation fuels being recognized, would there be reason for concern with heating fuels? As the new year approached, the refineries seemed to have no problem with supplies and RFG stocks were eased in about the second week of December. In Maine, the southern half of the state was effected by the gasoline substitution but seven of Maine`s sixteen counties were directed to follow the recommended criteria. Since the major population concentration lies in the southern three counties, concern was real. Attention paid to emission testing had come to a head in the fall, and RFG complaints were likely. There have been years when snow and cold arrived by Thanksgiving Day. In northern Maine, snow easily covers the ground before the SHOPP survey begins. The fall slipped by with no great shocks in the weather. December was more of the same, as the weather continued to favor the public. Normally the third week in January is considered the coldest time in the year, but not this year. By the end of January, two days were recorded as being more typical of winter. By March and the end of the survey season, one could only recognize that there were perhaps a few cold days this winter. Fuel prices fluctuated little through the entire heating season. There were no major problems to report and demand never placed pressure on dealers.

Seasonality in the Natural Gas Balancing Item: Historical Trends and  

Gasoline and Diesel Fuel Update (EIA)

Analysis > Seasonality in the Natural Gas Balancing Item: Historical Trends and Corrective Measures Analysis > Seasonality in the Natural Gas Balancing Item: Historical Trends and Corrective Measures Seasonality in the Natural Gas Balancing Item: Historical Trends and Corrective Measures Released: June 4, 2010 Download Full Report (PDF) This special report examines an underlying cause of the seasonal pattern in the balancing item published in the Natural Gas Monthly. Research finds that a significant portion of data collected on EIAÂ’s primary monthly natural gas consumption survey reflects billing data that does not strictly coincide with the actual calendar month, which creates an aggregate-level discrepancy with EIAÂ’s other natural gas supply and disposition data series. This discrepancy is especially observable during the fall and spring as one transitions into and out of the winter heating season. The report also outlines improved data collection and estimation procedures that will be implemented later this year to more closely align reported and actual calendar month consumption. This discussion will be helpful to users of EIAÂ’s volumetric natural gas data. Questions about this report should be directed to Andy Hoegh at andrew.hoegh@eia.doe.gov or (202) 586-9502.

Seasonal isotope and trace-metal profiles of serially-sampled Conus gastropods: proxies for paleoenvironmental change  

E-Print Network (OSTI)

We test the fidelity of shallow-water gastropod skeletons as multi-proxy archives of seasonal paleo-environmental change by performing isotopic and trace-metal analyses on specimens of Conus ermineus from the Gulf of Mexico. Four adult specimens were collected from Stetson Bank in the Flower Garden Banks National Marine Sanctuary during the summer of 2002. Shell samples were milled along axes of growth to produce time-series profiles spanning up to eight years. We corrected the profiles for growth rate effects and compared the tuned results with in situ temperature and salinity records at the reef surface and temperature profiles from nearby surface buoys. Examination of sample densities in ?18O cycles shows that shell growth is faster during summers and slower during winters. Tuning the profiles versus time yields ?18O values that co-vary closely with seasonal temperatures to a high degree of coherency (R2 = 0.84). The ?13C profiles show cyclic variation modified by ontogenetic decreases in ?13C. These ontogenetic trends are attributable to decreasing metabolic efficiency, while seasonal cycles reflect hydrographic changes in the gastropodsÂ? habitat. Salinity and ?13C of dissolved inorganic carbon show a strong correlation at Stetson Bank (R2 = 0.80), and early summer shell ?13C minima coincide with local salinity minima during times of peak river discharge. The terminations of these ?13C minima occur during annual upcoast reversals of shelf currents in this area. These effects are augmented by summer stratification and productivity minima that further decrease seawater ?13C. Sr/Ca ratios increase through ontogeny, most likely due to decreasing metabolic efficiency. However, seasonal variations in Sr/Ca profiles show strong similarity with ?18O profiles, confirming the temperature dependence of Sr/Ca and minimal influence of salinity on shell ?18O at Stetson Bank. The results of this study show that tuned ?18O and Sr/Ca profiles can be used to reconstruct seasonal paleotemperatures. Carbon isotope profiles and environmental data also demonstrate the utility of Conus ?13C as a proxy for freshwater flux and shelf circulation.

Analysis of the seasonal performance of hybrid desiccant cooling systems  

DOE Green Energy (OSTI)

A simulation model for the liquid desiccant component of a hybrid system was developed. An analysis of experimental test data was conducted. The liquid desiccant component was examined and the sensitivity of its seasonal performance to changes in principal component variables was identified. Seasonal simulations were performed on different operation modes of a hybrid liquid desiccant cooling system. The results were analyzed in terms of estimated operational costs and compared to the equivalent cost estimation of a conventional cooling system. The study showed that the investigated liquid desiccant configuration usually will not lower the costs of operation. A suggestion of an improved system is made.

Fischer Journal Geophysical Research Letters Volume 39 Issue 16 Keywords atmospheric transport, inverse modeling, nitrous oxide Abstract We estimate nitrous oxide (N2O) emissions from Central California for the period of December 2007 through November 2009 by comparing N2O mixing ratios measured at a tall tower (Walnut Grove, WGC) with transport model predictions based on two global a priori N2O emission models (EDGAR32 and EDGAR42). Atmospheric particle trajectories and surface footprints are computed using the Weather Research and Forecasting (WRF) and Stochastic Time-Inverted Lagrangian Transport (STILT) models. Regression analyses show that the slopes of predicted on measured N2O from both emission models are low, suggesting that actual N2O emissions are significantly higher than the EDGAR inventories for all seasons. Bayesian inverse analyses of regional N2O emissions show that posterior annual N2O emissions are larger than both EDGAR inventories by factors of 2.0 ± 0.4 (EDGAR32) and 2.1 ± 0.4 (EDGAR42) with seasonal variation ranging from 1.6 ± 0.3 to 2.5 ± 0.4 for an influence region of Central California within approximately 150 km of the tower. These results suggest that if the spatial distribution of N2O emissions in California follows the EDGAR emission models, then actual emissions are 2.7 ± 0.5 times greater than the current California emission inventory, and total N2O emissions account for 8.1 ± 1.4% of total greenhouse gas emissions from California.

Handbook of normal frames and coordinates  

E-Print Network (OSTI)

The main subject of the book is an up-to-date and in-depth survey of the theory of normal frames and coordinates in differential geometry. The book can be used as a reference manual, review of the existing results and introduction to some new ideas and developments. In the book can be found practically all existing essential results and methods concerning normal frames and coordinates. Most of the results are represented in full detail with full, in some cases new, proofs. All classical results are expanded and generalized in various directions. Theorems of existence, uniqueness and, possibly, holonomicity of the normal frames and coordinates are proved; mostly, the proofs are constructive and some their parts can be used independently for other tasks. Besides published results, their extensions and generalizations, the book contains completely new results which appear for the first time.

Seasonal efficiencies of residential heat pump air conditioners with inverter-driven compressors  

SciTech Connect

This paper describes a study to experimentally determine the steady-state characteristics, cyclic effect, and frosting/defrosting effect of a inverter heat pump currently available on the Japanese market and compute its seasonal efficiency based on the local outdoor air temperature data. It has been found that the APF of this heat pump is higher by 15% than that of the conventional fixed-speed heat pump. If cyclic and frosting/defrosting losses are eliminated, the APF of the inverter heat pump will be further improved by 2% to 6%. For the evaluation of an inverter heat pump, APF alone is not sufficient, and an additional parameter such as an annual comfort factor (ACF) is needed.

Dissolved organic matter discharge in the six largest arctic rivers-chemical composition and seasonal variability  

E-Print Network (OSTI)

The vulnerability of the Arctic to climate change has been realized due to disproportionately large increases in surface air temperatures which are not uniformly distributed over the seasonal cycle. Effects of this temperature shift are widespread in the Arctic but likely include changes to the hydrological cycle and permafrost thaw, which have implications for the mobilization of organic carbon into rivers. The focus of this research was to describe the seasonal variability of the chemical composition of dissolved organic matter (DOM) in the six largest Arctic rivers (Yukon, Mackenzie, Ob, Yenisei, Lena and Kolyma) using optical properties (UV-Vis Absorbance and Fluorescence) and lignin phenol analysis. We also investigated differences between rivers and how watershed characteristics influence DOM composition. Dissolved organic carbon (DOC) concentrations followed the hydrograph with highest concentrations measured during peak river flow. The chemical composition of peak-flow DOM indicates a dominance of freshly leached material with elevated aromaticity, larger molecular weight, and elevated lignin yields relative to base-flow DOM. During peak flow, soils in the watershed are still frozen and snowmelt water follows a lateral flow path to the river channels. As the soils thaw, surface water penetrates deeper into the soil horizons leading to lower DOC concentrations and likely altered composition of DOM due to sorption and microbial degradation processes. The six rivers studied here shared a similar seasonal pattern and chemical composition. There were, however, large differences between rivers in terms of total carbon discharge reflecting the differences in watershed characteristics such as climate, catchment size, river discharge, soil types, and permafrost distribution. The large rivers (Lena, Yenisei), with a greater proportion of permafrost, exported the greatest amount of carbon. The Kolyma and Mackenzie exported the smallest amount of carbon annually, however, the discharge weighted mean DOC concentration was almost 2-fold higher in the Kolyma, again, indicating the importance of continuous permafrost. The quality and quantity of DOM mobilized into Arctic rivers appears to depend on the relative importance of surface run-off and extent of soil percolation. The relative importance of these is ultimately determined by watershed characteristics.

Seasonal variation of CH4 emissions from central California

Seasonal variation of CH4 emissions from central California Seasonal variation of CH4 emissions from central California Title Seasonal variation of CH4 emissions from central California Publication Type Journal Article Year of Publication 2012 Authors Jeong, Seongeun, Chuanfeng Zhao, Arlyn E. Andrews, Laura Bianco, James M. Wilczak, and Marc L. Fischer Journal Journal of Geophysical Research - Atmospheres Volume 117 Issue D11 Keywords atmospheric transport, emission inventory, greenhouse gas, inverse model, methane Abstract We estimate seasonal variations in methane (CH4) emissions from central California from December 2007 through November 2008 by comparing CH4 mixing ratios measured at a tall tower with transport model predictions based on a global 1° a priori CH4emissions map (EDGAR32) and a 10 km seasonally varying California-specific map, calibrated to statewide by CH4emission totals. Atmospheric particle trajectories and surface footprints are computed using the Weather Research and Forecasting and Stochastic Time-Inverted Lagrangian Transport models. Uncertainties due to wind velocity and boundary layer mixing depth are evaluated using measurements from radar wind profilers. CH4signals calculated using the EDGAR32 emission model are larger than those based on the California-specific model and in better agreement with measurements. However, Bayesian inverse analyses using the California-specific and EDGAR32 maps yield comparable annually averaged posterior CH4emissions totaling 1.55 ± 0.24 times and 1.84 ± 0.27 times larger than the California-specific prior emissions, respectively, for a region of central California within approximately 150 km of the tower. If these results are applicable across California, state total CH4 emissions would account for approximately 9% of state total greenhouse gas emissions. Spatial resolution of emissions within the region near the tower reveal seasonality expected from several biogenic sources, but correlations in the posterior errors on emissions from both prior models indicate that the tower footprints do not resolve spatial structure of emissions. This suggests that including additional towers in a measurement network will improve the regional specificity of the posterior estimates.

Seasonal Contrasts in the Surface Energy Balance of the Sahel  

SciTech Connect

Over most of the world ocean, heating of the surface by sunlight is balanced predominately by evaporative cooling. Even over land, moisture for evaporation is available from vegetation or the soil reservoir. However, at the ARM Mobile Facility in Niamey, Niger, soil moisture is so depleted that evaporation makes a significant contribution to the surface energy balance only at the height of the rainy season, when precipitation has replenished the soil reservoir. Using observations at the Mobile Facility from late 2005 to early 2007, we describe how the surface balances radiative forcing. How the surface compensates time-averaged solar heating varies with seasonal changes in atmospheric water vapor, which modulates the greenhouse effect and the ability of the surface to radiate thermal energy directly to space. During the dry season, sunlight is balanced mainly by longwave radiation and the turbulent flux of sensible heat. The ability of longwave radiation to cool the surface drops after the onset of the West African summer monsoon, when moist, oceanic air flows onshore, increasing local column moisture and atmospheric opacity at these wavelengths. After the monsoon onset, but prior to significant rainfall, solar heating is compensated mainly by the sensible heat flux. During the rainy season, the magnitude of evaporation is initially controlled by the supply of moisture from precipitation. However, by the height of the rainy season, sufficient precipitation has accumulated at the surface that evaporation is related to the flux demanded by solar radiation, and radiative forcing of the surface is balanced comparably by the latent, sensible, and longwave fluxes. Radiative forcing of the surface also varies on a subseasonal time scale due to fluctuations in water vapor, clouds, and aerosol concentration. Except at the height of the rainy season, subseasonal forcing is balanced mainly by sensible heating and longwave anomalies. The efficacy of the sensible heat flux depends upon a positive feedback, where forcing changes mixing within the boundary layer and amplifies the sensible heating anomaly. How the surface responds to radiative forcing is fundamental to the climate response to dust and carbonaceous aerosols.

Thus, the aim of this study is to look at the characteristics of clouds and precipitation in the area around Darwin and to compare the cloud statistics estimated from geostationary meteorological satellite (GMS) satellite data with other nearby regions. Towards this end, GMS satellite imagery and radar data from

Target Dependent Score Normalization Techniques and . . .  

E-Print Network (OSTI)

Score normalization methods in biometric verification, which encompass the more traditional user-dependent decision thresholding techniques, are reviewed from a test hypotheses point of view. These are classified into test dependent and target dependent methods. The focus of the paper is on target dependent methods, which are further classified into impostor-centric, target-centric and target-impostor. These are applied to an on-line signature verification system on signature data from SVC 2004. In particular, a target-centric technique based on a variant of the cross-validation procedure provides the best relative performance improvement both for skilled (19%) and random forgeries (53%) as compared to the raw verification performance without score normalization (7.14% EER and 1.06% EER for skilled and random forgeries respectively).

Insolation data manual and direct normal solar radiation data manual  

DOE Green Energy (OSTI)

The Insolation Data Manual presents monthly averaged data which describes the availability of solar radiation at 248 National Weather Service (NWS) stations, principally in the United States. Monthly and annual average daily insolation and temperature values have been computed from a base of 24--25 years of data, generally from 1952--1975, and listed for each location. Insolation values represent monthly average daily totals of global radiation on a horizontal surface and are depicted using the three units of measurement: kJ/m{sup 2} per day, Btu/ft{sup 2} per day and langleys per day. Average daily maximum, minimum and monthly temperatures are provided for most locations in both Celsius and Fahrenheit. Heating and cooling degree-days were computed relative to a base of 18.3 C (65 F). For each station, global {bar K}{sub T} (cloudiness index) values were calculated on a monthly and annual basis. Global {bar K}{sub T} is an index of cloudiness and indicates fractional transmittance of horizontal radiation, from the top of the atmosphere to the earth's surface. The second section of this volume presents long-term monthly and annual averages of direct normal solar radiation for 235 NWS stations, including a discussion of the basic derivation process. This effort is in response to a generally recognized need for reliable direct normal data and the recent availability of 23 years of hourly averages for 235 stations. The relative inaccessibility of these data on microfiche further justifies reproducing at least the long-term averages in a useful format. In addition to a definition of terms and an overview of the ADIPA model, a discussion of model validation results is presented.

What Is the New Normal Unemployment Rate?  

E-Print Network (OSTI)

Recent labor markets developments, including mismatches in the skills of workers and jobs, extended unemployment benefits, and very high rates of long-term joblessness, may be impeding the return to “normal ” unemployment rates of around 5%. An examination of alternative measures of labor market conditions suggests that the “normal ” unemployment rate may have risen as much as 1.7 percentage points to about 6.7%, although much of this increase is likely to prove temporary. Even with such an increase, sizable labor market slack is expected to persist for years. In the past, the U.S. labor market has proven to be very flexible and recessions have not usually been followed by long-lasting increases in the unemployment rate. But, in the wake of the most recent recession, many economists are concerned that developments such as mismatches in the skills of workers and jobs, extended unemployment benefits, and a rise in long-term joblessness may have raised the “normal ” or “natural ” rate of unemployment above the 5 % level that was thought to be typical before the downturn. Indeed, a few economists have gone so far as to argue that the rise in the unemployment rate to its current level of 9 % primarily reflects an increase in the natural rate, implying there is little slack in labor markets and therefore little downward pressure on inflation.

Variable temperature seat climate control system  

DOE Patents (OSTI)

A temperature climate control system comprises a variable temperature seat, at least one heat pump, at least one heat pump temperature sensor, and a controller. Each heat pump comprises a number of Peltier thermoelectric modules for temperature conditioning the air in a main heat exchanger and a main exchanger fan for passing the conditioned air from the main exchanger to the variable temperature seat. The Peltier modules and each main fan may be manually adjusted via a control switch or a control signal. Additionally, the temperature climate control system may comprise a number of additional temperature sensors to monitor the temperature of the ambient air surrounding the occupant as well as the temperature of the conditioned air directed to the occupant. The controller is configured to automatically regulate the operation of the Peltier modules and/or each main fan according to a temperature climate control logic designed both to maximize occupant comfort during normal operation, and minimize possible equipment damage, occupant discomfort, or occupant injury in the event of a heat pump malfunction.

Variability in Measured Space Temperatures in 60 Homes  

SciTech Connect

This report discusses the observed variability in indoor space temperature in a set of 60 homes located in Florida, New York, Oregon, and Washington. Temperature data were collected at 15-minute intervals for an entire year, including living room, master bedroom, and outdoor air temperature (Arena, et. al). The data were examined to establish the average living room temperature for the set of homes for the heating and cooling seasons, the variability of living room temperature depending on climate, and the variability of indoor space temperature within the homes. The accuracy of software-based energy analysis depends on the accuracy of input values. Thermostat set point is one of the most influential inputs for building energy simulation. Several industry standards exist that recommend differing default thermostat settings for heating and cooling seasons. These standards were compared to the values calculated for this analysis. The data examined for this report show that there is a definite difference between the climates and that the data do not agree well with any particular standard.

Humidity-temperature relationships in the tropical troposphere  

SciTech Connect

Based on the observed interannual variations of water vapor and temperature over the past 26 years the authors have examined the relationship between the variations of water vapor and temperature in the tropical troposphere. In both the lower and upper troposphere, tropical mean specific humidity increases with temperature. The rate of fractional increase of specific humidity with temperature at 500 mb is as large as that in the surface boundary layer. However, the rate of fractional increase of specific humidity with temperature is significantly smaller than that given by a model with a fixed relative humidity, particularly in the region immediately above the tropical convective boundary layer. The variations of tropical mean relative humidity show consistently a negative correlation with the temperature variations. The authors have further compared the spatial structure of the specific humidity variations with that of the temperature variations. Though the vertical structure of tropical mean specific humidity has more variability than that of the tropical mean temperature, the leading EOF for the normalized specific humidity variations is almost exactly the same as the leading EOF for the normalized temperature variations. The characteristic horizontal structure of the specific humidity variations at levels in the free troposphere, however, is very different from that of the temperature variations. The leading EOF for the normalized specific humidty variations at levels in the free troposphere is characterized by regions with alternating positive and negative signs, while the leading EOF for the corresponding temperature variations has a single sign throughout the Tropics. When the variations are averaged zonally, the leading EOF for the normalized specific humidity variations still differs significantly from that of the normalized temperature variations, but the leading EOF has the same sign from the deep Tropics to the subtropics. 31 refs., 15 figs., 1 tab.

Prediction of regional seasonal fluctuations in precipitation based on chaos theory  

E-Print Network (OSTI)

In the past decade, the combined effect of flood and drought resulted in the loss of thousands of lives and billions of dollars. Prediction of regional precipitation is important for a multitude of reasons. However, the evolution of climate is highly sensitive to initial conditions, or chaotic, so practical long term prediction of precipitation in time is impossible. Adding to the difficulty, the climate system is non-stationary; with the energy available to move water and air as tracked by global surface air temperature (GSAT) increasing over the last several decades. Neither purely empirical autoregression, nor global circulation models (GCM) are sufficiently accurate. Here I use statistical methods motivated by chaos theory to predict seasonal fluctuations in regional and local precipitation with high correlation. The change in GSAT is accommodated using special runs of a global climate model to build an initial set of predictive models, while ground data is used to train, combine, and calibrate them. In examples I show seasonal prediction of precipitation in a few geographical regions with high statistical significance. In one region were precipitation rose near the 4 sigma level above the mean, the correlation was above 0.8. Also, I examine one region over longer time and tentatively identifying a tight coupling between GSAT and patterns of climate anomalies, with implications for attribution. This demonstration of invertability of the climate patterns to identify parameters of the climate system holds promise for allowing statistical evaluation of parameterizations of climate models. I expect these methods may be applicable both to a number of other measures of climate and weather as well as other high dimensional chaotic systems.

Normal Modes of Black Hole Accretion Disks  

SciTech Connect

This paper studies the hydrodynamical problem of normal modes of small adiabatic oscillations of relativistic barotropic thin accretion disks around black holes (and compact weakly magnetic neutron stars). Employing WKB techniques, we obtain the eigen frequencies and eigenfunctions of the modes for different values of the mass and angular momentum of the central black hole. We discuss the properties of the various types of modes and examine the role of viscosity, as it appears to render some of the modes unstable to rapid growth.

Atmospheric mercury in Changbai Mountain area, northeastern China I. The seasonal distribution pattern of total gaseous mercury and its potential sources  

SciTech Connect

An intensive field campaign for the measurement of total gaseous mercury (TGM) concentrations in ambient air was conducted in Changbai Mountain area from 5 August 2005 to 5 July 2006 using an automatic atmospheric mercury analyzer (Tekran 2537A), which was the first time TGM was monitored at a remote area in northeastern China. 99% of the hourly TGM concentrations fell between 1.28 and 9.49 ng m{sup -3} with an annual arithmetic mean of 3.58{+-}1.78 ng m{sup -3}, which was significantly elevated compared to values obtained in remote areas of Europe and North America. Seasonal mean TGM concentrations displayed a descending trend as follows: winter, spring, fall, and summer. Compared to spring/winter, TGM concentrations were lower in the summer/fall but the standard deviation (SD) of TGM levels was higher and indicated a correlation with anthropogenic emissions. TGM concentrations showed seasonal differences with respect to meteorological parameters: TGM levels in spring/winter were most correlated with wind speed, and correlated with solar radiation only in the winter, while TGM levels in summer/fall periods were most correlated with air temperature. There was a strong diurnal variation of seasonal TGM with significantly higher concentrations in daytime/nighttime compared to the early morning. The seasonal diel TGM pattern indicated regional biofuel and coal combustion were the primary mercury sources.

Cooled, temperature controlled electrometer  

DOE Patents (OSTI)

A cooled, temperature controlled electrometer for the measurement of small currents. The device employs a thermal transfer system to remove heat from the electrometer circuit and its environment and dissipate it to the external environment by means of a heat sink. The operation of the thermal transfer system is governed by a temperature regulation circuit which activates the thermal transfer system when the temperature of the electrometer circuit and its environment exceeds a level previously inputted to the external variable temperature control circuit. The variable temperature control circuit functions as subpart of the temperature control circuit. To provide temperature stability and uniformity, the electrometer circuit is enclosed by an insulated housing.

Coronal mass ejections and geomagnetic storms: Seasonal variations  

Science Conference Proceedings (OSTI)

The well-established semiannual geomagnetic cycle, with peak activity near the equinoxes, has been attributed to the angle between the solar rotation axis and the geomagnetic dipole, which modulates the GSM Bz component in the interplanetary magnetic field (MF). This effect is predicted to be accentuated in the shocked plasma ahead of fast coronal mass ejections (CMESs); its relevance to the internal fields of the ejecta is unclear. CMEs, particularly fast events driving interplanetary shocks, are the cause of almost all large geomagnetic storms near solar maximum. We use a set of CMEs identified by ISEE-3 observations of bidirectional electron streaming, plus IMF and geomagnetic data, to investigate the semiannual geomagnetic variation and its relation to CMEs. We find that the geomagnetic effectiveness of CMEs and post-shock solar wind is well-ordered by speed and by the southward component of the IMF in GSM coordinates, as well as by preexisting geomagnetic conditions. The post-shock seasonal effect, with geomagnetic effectiveness maximizing near April 5 for negative GSEQ By and near October 5 for positive GSEQ By, is identifiable in shock and shock/CME events, but not for CME events without leading shocks. When used to complement the more fundamental causal parameter of CME speed, the seasonal effect appears to have value for prediction of geomagnetic storms.

Thermochemical seasonal energy storage for solar thermal power  

DOE Green Energy (OSTI)

During the many years that thermochemical energy storage has been under investigation, the concept has been plagued with two persistent problems: high capital cost and poor efficiency. Literally hundreds of chemical reactions have also been carried out. For short-term storage, thermochemical systems suffer in comparison with highly efficient sensible storage media such as molten salts. Long-term storage, on the other hand, is not cost-competitive with systems employing fossil backup power. Thermochemical storage will play a significant role in solar thermal electric conversion only under highly select circumstances. The portion of electric demand served by solar plants must be sufficiently high that the balance of the grid cannot fully supplant seasonal storage. High fossil fuel costs must preclude the use of gas turbines for backup power. Significant breakthroughs in the development of one or more chemical reaction systems must occur. Ingeniously integrated systems must be employed to enhance the efficiency and cost-effectiveness of thermochemical storage. A promising integration scheme discussed herein consists of using sensible storage for diurnal cycling in parallel with thermochemical seasonal storage. Under the most favorable circumstances, thermochemical storage can be expected to play a small but perhaps vital role in supplying baseload energy from solar thermal electric conversion plants.

Asymptotic normalization coefficients from ab initio calculations.  

Science Conference Proceedings (OSTI)

We present calculations of asymptotic normalization coefficients (ANCs) for one-nucleon removals from nuclear states of mass numbers 3 {le} A {le} 9. Our ANCs were computed from variational Monte Carlo solutions to the many-body Schroedinger equation with the combined Argonne v{sub 18} two-nucleon and Urbana IX three-nucleon potentials. Instead of computing explicit overlap integrals, we applied a Green function method that is insensitive to the difficulties of constructing and Monte Carlo sampling the long-range tails of the variational wave functions. This method also allows computation of the ANC at the physical separation energy, even when it differs from the separation energy for the Hamiltonian. We compare our results, which for most nuclei are the first ab initio calculations of ANCs, with existing experimental and theoretical results and discuss further possible applications of the technique.

National micro-data based model of residential electricity demand: new evidence on seasonal variation  

SciTech Connect

Building on earlier estimates of electricity demand, the author estimates elasticities by month to determine differences between heating and cooling seasons. He develops a three equation model of residential electricity demand that includes all the main components of economic theory. The model generates seasonal elasticity estimates that generally support economic theory. Based on the model using a national current household data set (monthly division), the evidence indicates there is a seasonal pattern for price elasticity of demand. While less pronounced, there also appears to be seasonal patterns for cross-price elasticity of alternative fuels, for the elasticity of appliance stock index, and for an intensity of use variable.

Fractal Fluctuations and Statistical Normal Distribution  

E-Print Network (OSTI)

Dynamical systems in nature exhibit selfsimilar fractal fluctuations and the corresponding power spectra follow inverse power law form signifying long-range space-time correlations identified as self-organized criticality. The physics of self-organized criticality is not yet identified. The Gaussian probability distribution used widely for analysis and description of large data sets underestimates the probabilities of occurrence of extreme events such as stock market crashes, earthquakes, heavy rainfall, etc. The assumptions underlying the normal distribution such as fixed mean and standard deviation, independence of data, are not valid for real world fractal data sets exhibiting a scale-free power law distribution with fat tails. A general systems theory for fractals visualizes the emergence of successively larger scale fluctuations to result from the space-time integration of enclosed smaller scale fluctuations. The model predicts a universal inverse power law incorporating the golden mean for fractal fluctuations and for the corresponding power spectra, i.e., the variance spectrum represents the probabilities, a signature of quantum systems. Fractal fluctuations therefore exhibit quantum-like chaos. The model predicted inverse power law is very close to the Gaussian distribution for small-scale fluctuations, but exhibits a fat long tail for large-scale fluctuations. Extensive data sets of Dow Jones index, Human DNA, Takifugu rubripes (Puffer fish) DNA are analysed to show that the space/time data sets are close to the model predicted power law distribution.

Yeast and Temperature Yeast and Temperature Name: Alyssaaum Location: N/A Country: N/A Date: N/A Question: How does temperature affect yeast? Replies: Dear Alyssa, At low temperatures (0-10 C) yeast will not grow, but not die either. At temperatures 10-37 C yeast will grow and multiply, faster at higher temperatures with an optimal growth at 30 or 37 C (that depends on the species). At higher temperature the cells become stressed, meaning that their content becomes damaged and which can be repaired to some degree. At high temperatures (>50 C) the cells die. The bacteria can survive freezing under certain conditions. When baking bread all yeast dies during the process. Dr. Trudy Wassenaar yeast is a unique type of fungi that grows quickly by rapid cell division. It grows best at about 100 degrees fahrenheit, colder will cause it to go dormant, much warmer could kill it

Effect of seasonal changes in quantities of biowaste on full scale anaerobic digester performance  

Science Conference Proceedings (OSTI)

A 750,000 l digester located in Roppen/Austria was studied over a 2-year period. The concentrations and amounts of CH{sub 4}, H{sub 2}, CO{sub 2} and H{sub 2}S and several other process parameters like temperature, retention time, dry weight and input of substrate were registered continuously. On a weekly scale the pH and the concentrations of NH{sub 4}{sup +}-N and volatile fatty acids (acetic, butyric, iso-butyric, propionic, valeric and iso-valeric acid) were measured. The data show a similar pattern of seasonal gas production over 2 years of monitoring. The consumption of VFA and not the hydrogenotrophic CH{sub 4} production appeared to be the limiting factor for the investigated digestion process. Whereas the changes in pH and the concentrations of most VFA did not correspond with changes in biogas production, the ratio of acetic to propionic acid and the concentration of H{sub 2} appeared to be useful indicators for reactor performance. However, the most influential factors for the anaerobic digestion process were the amount and the quality of input material, which distinctly changed throughout the year.

NGNP/HTE full-power operation at reduced high-temperature heat exchanger temperatures.  

Science Conference Proceedings (OSTI)

Operation of the Next Generation Nuclear Plant (NGNP) with reduced reactor outlet temperature at full power was investigated for the High Temperature Electrolysis (HTE) hydrogen-production application. The foremost challenge for operation at design temperature is achieving an acceptably long service life for heat exchangers. In both the Intermediate Heat Exchanger (IHX) and the Process Heat Exchanger (PHX) (referred to collectively as high temperature heat exchangers) a pressure differential of several MPa exists with temperatures at or above 850 C. Thermal creep of the heat exchanger channel wall may severely limit heat exchanger life depending on the alloy selected. This report investigates plant performance with IHX temperatures reduced by lowering reactor outlet temperature. The objective is to lower the temperature in heat transfer channels to the point where existing materials can meet the 40 year lifetime needed for this component. A conservative estimate for this temperature is believed to be about 700 C. The reactor outlet temperature was reduced from 850 C to 700 C while maintaining reactor power at 600 MWt and high pressure compressor outlet at 7 MPa. We included a previously reported design option for reducing temperature at the PHX. Heat exchanger lengths were adjusted to reflect the change in performance resulting from coolant property changes and from resizing related to operating-point change. Turbomachine parameters were also optimized for the new operating condition. An integrated optimization of the complete system including heat transfer equipment was not performed. It is estimated, however, that by performing a pinch analysis the combined plant efficiency can be increased from 35.5 percent obtained in this report to a value between 38.5 and 40.1 percent. Then after normalizing for a more than three percent decrease in commodities inventory compared to the reference plant, the commodities-normalized efficiency lies between 40.0 and 41.3. This compares with a value of 43.9 for the reference plant. This latter plant has a reactor outlet temperature of 850 C and the two high temperature heat exchangers. The reduction in reactor outlet temperature from 850 C to 700 C reduces the tritium permeability rate in the IHX metal by a factor of three and thermal creep by five orders of magnitude. The design option for reducing PHX temperature from 800 C to 200 C reduces the permeability there by three orders of magnitude. In that design option this heat exchanger is the single 'choke-point' for tritium migration from the nuclear to the chemical plant.

Environmental and societal consequences of a possible CO/sub 2/-induced climate change. Volume II, Part 8. Impacts of rising atmospheric carbon dioxide levels on agricultural growing seasons and crop water use efficiencies  

Science Conference Proceedings (OSTI)

The researchable areas addressed relate to the possible impacts of climate change on agricultural growing seasons and crop adaptation responses on a global basis. The research activities proposed are divided into the following two main areas of investigation: anticipated climate change impacts on the physical environmental characteristics of the agricultural growing seasons and, the most probable food crop responses to the possible changes in atmospheric CO/sub 2/ levels in plant environments. The main physical environmental impacts considered are the changes in temperature, or more directly, thermal energy levels and the growing season evapotranspiration-precipitation balances. The resulting food crop, commercial forest and rangeland species response impacts addressed relate to potential geographical shifts in agricultural growing seasons as determined by the length in days of the frost free period, thermal energy changes and water balance changes. In addition, the interaction of possible changes in plant water use efficiencies during the growing season in relationship to changing atmospheric CO/sub 2/ concentrations, is also considered under the scenario of global warming due to increases in atmospheric CO/sub 2/ concentration. These proposed research investigations are followed by adaptive response evaluations.

Measured energy savings from using night temperature setback  

SciTech Connect

The measured energy savings resulting from using night temperature setback in typical light-construction wooden office buildings was determined. Researchers installed monitoring equipment in a six-building sample of two-story wooden buildings at Fort Devens, Massachusetts. Data obtained during both single-setting and night-setback operating modes were used to develop models of each building`s heat consumption as a function of the difference between inside and outside temperature. These models were used to estimate seasonal savings that could be obtained from the use of night-setback thermostat control. The measured savings in heating energy from using night temperature setback for the six Fort Devens buildings ranged from 14% to 25%; the mean savings was 19.2%. Based on an energy cost of $0.65/therm of natural gas, the estimated average cost savings of using automatic setback thermostats in these buildings is $780 per year per building.

The measured savings in heating energy from using night temperature setback for the six Fort Devens buildings ranged from 14% to 25%; the mean savings was 19.2%. Based on an energy cost of $0.65/therm of natural gas, the estimated average cost savings of using automatic setback thermostats in these buildings is $780 per year per building.

Daily Temperature Lag Daily Temperature Lag Name: Shyammayi Status: teacher Grade: K-2 Country: Mauritius Date: Summer 2011 Question: At what time of the day is the temperature hottest? At what time of the day is the temperature coldest? Replies: In general, the hottest part of the day is late afternoon. The sun has passed its peak in the sky but still heats the Earth up until very late in the afternoon. The lowest temperatures are around dawn. Earth has had all night to get rid of the day's heat by radiating it into space. After sunrise, temperatures begin to climb. This can be changed by local storms, sea breezes or mountain breezes and even monsoon winds. Hope this helps. R. W. "Bob" Avakian Instructor Arts and Sciences/CRC Oklahoma State Univ.
