Synoptic and mesoscale circulations and precipitation mechanisms in shallow upslope storms over the western High Plains.

Abstract

It is generally believed that synoptically driven storms, with lifting induced or enhanced by upslope flow over the high plains, produce most of the winter precipitation in eastern Colorado. Two extremely different circulations, the fully developed extratropical cyclone and the shallow arctic anticyclone, bound the range of upslope circulations. Two cases involving shallow upslope circulations were studied in detail for this work. -from Authors
