Analysis of Roanoke Region Weather Patterns Under Global Teleconnections
… North American (PNA) pattern to synoptic-scale weather patterns and precipitation in the Roanoke, Virginia region. The first chapter describes the behavior of the El Nino-Southern Oscillation (ENSO) by implementing non-homogeneous and homogeneous Markov Chain models on a monthly time series of …

Synoptic Scale Weather Patterns Associated with Annual Snow Accumulation Variability in North-Central Greenland
… Version 2 (1870 to 2008)) to identify recurring patterns in the sea level pressure (SLP) field that impact meteorological processes and explain annual variations of accumulation over North-Central Greenland for the 118 year period. The SOM algorithm identified 36 representative daily SLP patterns …

The role of soil moisture and weather patterns for flood occurrence and characteristics at the river basin scale
… is developed and a probabilistic link between patterns of soil moisture and flood occurrence is established. The soil moisture classification is applied to continuously simulated soil moisture data which is generated using the semi-distributed conceptual rainfall-runoff model SWIM. Applying …

The effects of regional weather patterns on the migration of birds and Lepidoptera to a coastal migration “hotspot” in East Kent and possible changes in occurrence in response to global climate change
… past literature covering the effects of weather on migration, a research gap was found that related to understanding between categorised, localised weather patterns on the migration of three groups: migratory breeding birds, vagrant birds and migratory moths and how climate change could …

Statistical approach to payload capability forecasting for large commercial aircraft operating payload range limited routes
… the route must be primarily influenced by global weather patterns rather than localised weather phenomena. To improve on the current monthly stepped approach the average wind components were modelled through a sinusoidal function, reflecting the annual repetitiveness of weather patterns. Long term …

Soil-Specific, Late-Season Nitrogen and Potassium Applications to Increase Corn Yields in the Mid-Atlantic Coastal Plain
… high yielding corn was measured, and historical weather patterns evaluated in an effort to predict the need for late-season fertilizer applications based on soil moisture. Grain yield was increased significantly by late-season N applications in three of four experiments. Potassium applications …

The influence of rainfall on the Verreaux's eagle and its prey species in the Matobo hills, Zimbabwe
… how species respond to variations in weather patterns will be crucial to improve our predictions about how species will cope with climate change. The Verreaux's Eagle (Aquila verreauxii) and its primary prey species the Rock Hyrax (Procavia capensis) and Yellow-spotted Hyrax …

Essays on valuing non-market goods in imperfectly competitive markets
… the existence of negative impacts of changing weather patterns. However, these impacts have not fully been assessed. One way which changing climates can negatively impact an economy is by changing the market structures of its most influential industries; making these markets more imperfectly …

Arctic synoptic activity associated with sea ice variability using self-organizing maps
… maps (SOMs) to categorize observed weather patterns over the 1979-2010 period. The European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-interim, or ERAI) provides the daily sea level pressures from which the SOMs are computed. Time series of frequencies and …

How to drive Thailand Developers Toward Net Zero: Lessons Learned from the Developer's Perspective and the Global Studies
… refers to long-term shifts in temperatures and weather patterns. Since the 1800s, human activities have been the key driver of climate change due to burning fossil fuels such as coal, oil, and gas, which generate greenhouse gas emissions that trap the sun's heat and raise temperatures. Climate …

Seasonal variation in population location of the Galapagos tortoise, geochelone elephantopus vandenburghi, on Volcan Alcedo, Isabela Island, Galapagos archipelago
… population movement and location.</p> <p>Weather data were collected and observations were made concerning the vegetation. These observations were compared with those from previous studies to see what impact seasonal climatic conditions and food availability had on tortoise movement.</p> …

Modeling Habitat and Environmental Factors Affecting Mosquito Abundance in Chesapeake, Virginia
… based digital data to analyze mosquito-abundance patterns in real landscapes.</p> <p>This research is presented in three major chapters: (II) a series of semi-static habitat suitability indices (HSI) grounded on well-documented associations between mosquito abundance and environmental variables, …

Machine Learning and Geostatistical Approaches for Discovery of Weather and Climate Events Related to El Niño Phenomena
… crises created by global warming and unusual weather patterns caused by El Nino and marine heatwaves in nesting sea turtle habitats. Finally, expanding this study on ENSO yielded novel ways to analyze and understand the underlying processes driving unprecedented global heat waves and their …

Classification of summertime West Coast fog and stratus events and the development of fog and stratus forecast techniques
… a classification scheme. The synoptic-scale weather patterns as well as the mesoscale coastal regime were then associated with a type of stratus evolution. The Navygass mesoscale model, coupled ocean/atmosphere mesoscale prediction system (COAMPS), provided detailed simulation of 11 events to …

Performance of dual polarized site diversity satellite communications systems
… including a new model which incorporates local weather patterns, are discussed and compared. The problem of how to select the best signals from the available diversity replicas is investigated for both PSK and FM modulation schemes. A new technique is proposed for combining the effects of …

Assessing Variabilities of Extreme Precipitation and Snow Depth Using Climate and Stochastic Models
… Climate change, with its associated extreme weather patterns, has exacerbated the frequency and intensity of these events. Specifically, heavy rainfall and rapid snowmelt have triggered extensive flooding in multiple provinces. As global temperatures rise and weather patterns change, the …
