Abstract: The first of two papers describing thunderstorms that occur above frontal surfaces, frequently in environments without positive convective available potential energy (CAPE), focuses on the climatology of such storms for ...

Abstract: The second of two papers describing thunderstorms that occur above frontal surfaces, frequently in environments without positive convective available potential energy (CAPE), focuses on an impressive outbreak of elevated ...

Abstract: A major snowstorm in Colorado is considered in order to demonstrate the utility of a quasigeostrophic (QG) diagnostic scheme that is capable of separating from the total QG forcing field the cross-isentrope, ageostrophic ...

Abstract: A quasigeostrophic (QG) diagnostic model is used to evaluate the nested grid model's (NGM) predictions for a December cyclone whose impact on northeastern Colorado was underpredicted. Although the NGM predicted deepening ...

Abstract: Severe downslope windstorms are a mesoscale, primarily wintertime, phenomenon that affect regions in the lee of large mountain ranges. The resolution of current weather prediction models is too coarse to explicitly predict ...

Abstract: The purpose of this study is to investigate the occurrence of severe winds in southeast Alaska (locally known as Taku winds) based on recent theoretical advances in the understanding of severe downslope windstorms. We found ...

Abstract: The Puget Sound Convergence Zone (PSCZ) is a terrain-induced mesoscale phenomenon that occurs in western Washington and has a dramatic impact on local weather. This paper presents the operational forecasting techniques ...

Abstract: The Coastal Observation and Simulation with Topography (COAST) program has examined the interaction of both steady-state and transient cool-season synoptic features, such as fronts and cyclones, with the coastal terrain ...

Abstract: Despite continual increases in numerical model resolution and significant improvements in the forecasting of many meteorological parameters, progress in quantitative precipitation forecasting (QPF) has been slow. This is ...
