Abstract: A climatological analysis, based upon operational surface and upper-air data from 1957 to 1994, of the wind and temperature profiles composited with respect to each quadrant of surface cyclones and anticyclones, is presented ...

Abstract: Moisture flux convergence (MFC) is a term in the conservation of water vapor equation and was first calculated in the 1950s and 1960s as a vertically integrated quantity to predict rainfall associated with synoptic-scale ...

Abstract: Although the relationship between the behavior of convective storms and their environmental vertical wind shear has been examined using proximity soundings and idealized numerical modeling experiments, the manner in which ...

Abstract: The occurrence of rare but significant severe weather events associated with elevated mixed-layer (EML) air in the northeastern United States is investigated herein. A total of 447 convective event days with one or more ...

Abstract: From 15 July through 30 September of 2001, an ensemble cloud-scale model was run for the Storm Prediction Center on a daily basis. Each ensemble run consisted of 78 members whose initial conditions were derived from the ...
