Projections of 500 hPa geopotential height (Z500) patterns over the Pacific Northwest of North America and their associated surface temperature, precipitation, and frequency of occurrence are assessed using models from the 6th phase of the Coupled Model Intercomparison Project (…

This dissertation examines the regional and seasonal variability of extreme precipitation and atmospheric rivers (ARs) across the contiguous United States (CONUS) in past, present, and future climates. An extreme precipitation categorization scheme, designed to monitor and track…

Freezing rain is a winter weather phenomenon that is both particularly dangerous and difficult to predict. This forecast challenge arises because freezing rain requires the maintenance of a narrow range of temperature profiles, with warm air aloft and cold air at the surface. Th…
