The Mesoscale Evolution of Explosive Cyclogenesis: A Numerical Study of the March 1993 Storm of the Century

Abstract

The early, overwater cyclogenesis of the March 12-14 1993 Storm of the Century (SOC93) is investigated using mesoscale simulation datasets. Numerical results indicate that the convective available potential energy for initial development; ;is supplied by a mid-level cold pool that develops in western Texas through evaporative cooling and convective overturning in the elevated mixed layer (EML). The EML and mountain-plains solenoid (MPS) endemic to the Mexican plateau interact with a terrain-induced low-level moist flow to sustain shallow convection in this layer; the resulting cold pool propagates to the Texas Gulf Coast early on 12 March.
