A Novel Road Grip Estimation Method Using a Vehicle as a Probe
Winter weather road maintenance has been a topic of discussion among many state Departments of Transportation (DoT) within the US and numerous countries across the globe. Several research efforts have been conducted with the common goal of making this seasonal activity more efficient and/or …

Winter Behavior and Ecology of Eastern Bluebirds (<i>Sialia sialis</i>): Home Ranges, Habitat Use, and Effect of Weather on Foraging Behavior
… populations appear to be susceptible to extreme winter weather. Declines in population following cold winters in states like Kentucky suggest the need to better understand winter-specific habitat requirements and behavioral responses to inclement weather. My objectives were to 1) describe the …

System Architecture for Weather, Road Condition, and Vehicle Data Telemetry via Low Bandwidth Radio Network
… purpose is to determine how localized, real-time winter weather, road condition, and vehicle-related data gathered by mobile, vehicle-based systems can be used to more effectively maintain roads, reduce operating costs through more efficient road maintenance, and improve responsiveness and …

An assessment of the nutritional status and habitat quality of a southwestern Virginia deer herd
… extent to which poaching, free-roaming dogs, and winter weather might be affecting the HK deer herd also was investigated. Pellet group density was significantly lower (P = 0.004) at HK relative to SC and was believed to be indicative of a somewhat lower herd density at HK. In September, the …

Movements and bioenergetics of canvasbacks wintering in the upper Chesapeake Bay
… energetics of canvasbacks (Aythya valisineria) wintering in the upper Chesapeake Bay, Maryland, were investigated. Eighty-seven juvenile female canvasbacks were radio-tracked between 30 December 1988 and 25 March 1989. Diurnal time and energy budgets were constructed for a time of day-season …

Regional estimates of the price elasticity of demand for natural gas in the United States
… reliability issues, particularly during severe winter weather when gas demand is high. The majority of proposed solutions have focused on increasing gas supply. However, demand response in the natural gas retail market is a potential alternative answer. To quantify the benefits of gas demand …

Exploring the potential impacts of climate change on North America's Laurentian Great Lakes tourism sector
… century and, given the important role that weather and climate play in all aspects of the tourism experience, tourism businesses owners need to start thinking about and enacting climate change adaptation strategies now. This work has utilized a combination of social science and physical …

Design and Lab Implementation of an Air Source Transcritical CO2 Heat Pump
… climate chamber was also constructed to simulate winter weather conditions typical of the northeastern United States. Both the TCHP and the chamber were fully instrumented to collect temperature, pressure, and mass flow data, which were used to calculate the co- efficient of performance (COP) in …

Far-flung influences on midlatitude weather and climate: The stratospheric pathway
… and enhance the predictability of, midlatitude winter weather on timescales of weeks to months – including the likelihood of weather extremes and associated impacts. This thesis first explores the response of the polar vortex to projected Arctic climate change, in terms of both the mean state …

EFFECTS OF ABIOTIC STRESS AND PREDATOR REFUGE ON TERRESTRIAL PREDATOR-PREY INTERACTIONS
… food web. I investigated the stress of winter weather and asked first, whether the top predator used a particular marsh habitat as a winter refuge, second, how inter-year variation in winter severity affected refuge use, and third, how refuge use affected the predator's spatial …

Ground-Source Bridge Deck Deicing and Integrated Shallow Geothermal Energy Harvesting Systems
… deck deicing. Bridge decks experience two main winter weather related problems. The first of which is preferential icing, where the bridge freezes before the adjacent roadway because the bridge undergoes hastened energy loss due to its exposed nature. The second problem is the accelerated …

Survival of Male Merriam's Wild Turkeys in the Northern Black Hills of South Dakota
… predation, presumed hunter crippling loss, weather-related mortalities, one vehicle collision and other unknown sources. Spring harvest was the primary source of mortality for marked males in the northern Black Hills (34%) during this study. Fall harvest accounted for 7% and an additional 7% …

Murgantia histrionica (Hahn): new trapping tactics and insights on overwintering survival
… into northern regions is limited by extreme winters. In 2014 and 2015 the arctic polar vortex extended into mid-latitudes bringing a blanket of sustained sub-freezing temperatures to much of the United States. We used these events to determine effects of extreme winter weather on harlequin …

Salt hydrates for thermochemical energy storage
… are possible to operate within New Zealand winter weather condition. However, it was found that in drier climates, the hydration reaction may not operate efficiently and could cause significant undesirable drop in indoor air humidity. Overall, based on the results of this work, salt hydrates …

THE EFFECT OF BIOTIC AND ABIOTIC FACTORS WITHIN THE SOIL ENVIRONMENT ON THE MORTALITY OF IXODES SCAPULARIS DURING THEIR OFF-HOST PERIODS
… I began by exploring the effect of hot, dry weather conditions on Lyme disease incidences in geographic areas with differing endemic histories. In long-term endemic areas the incidence of Lyme disease was significantly lower during hot and dry weather, while in areas that have become endemic …

Analysis of vertical velocities and elevated instability in the comma-head of continental winter cyclones
… within the comma heads of three continental winter cyclones are investigated using the Wyoming W-band Cloud Radar mounted on the NSF/NCAR C-130, supplemented by analyses from the Rapid Update Cycle model and WSR-88D data. The cyclones followed three distinct archetypical tracks and were …
