Searching For Melting-Induced Cold-Pool Circulations In An Oklahoma Winter Storm, Gabriel Susca-Lopata

Atmospheric & Environmental Sciences

This paper investigates the thermodynamic and dynamic impacts of melting precipitation through a case study of an Oklahoma winter storm. On 28 January 2005 a rain and snow event affected the state of Oklahoma. A combination of radiosonde data, wind profiler data, radar imagery and Oklahoma Mesonet surface data show that latent cooling from melting caused the surface temperatures to fall in western Oklahoma while evaporation caused surface cooling in central and eastern Oklahoma. The wind and surface pressure fields in western Oklahoma are analyzed along with radar data from Frederick Air Force Base, and some limited evidence for melting-driven …
