Robert Wilhelmson Romine, Glen Scott 2015-09-28T14:52:23Z 2015-09-28T14:52:23Z 10000-01-01 2008 2008 A detailed examination of the case study led to new insight into polarimetric field evolution associated with a significantly tornadic supercell thunderstorm. This included the identification of a specific differential phase foot and differential reflectivity shield as well as the first documentation focused on the relationship between polarimetric field evolution relative to surface gust front behavior. A strong but compact cold pool was found on the upshear side of the storm. However, an intriguing discovery was the lack of significant cooling at the surface within the forward flank downdraft region of the storm. Instead, there was an elevated cold pool along the forward storm flank that rested on a capping inversion layer. Comparison of the retrieved atmospheric state variables between the simple and advanced microphysical representation showed significant differences in spatial and temporal evolution, yet retrieved cold pool characteristics were qualitatively quite similar to one another and observations. This is related to the similar treatment of evaporation between the two microphysical schemes along the upshear side of the storm. Made available in DSpace on 2015-09-28T14:52:23Z (GMT).
