Description

Polarimetric radar signatures associated with deep moist convective updrafts are analyzed to provide information on the prevalence and variability of microphysically meaningful characteristics of these features. ARM CSAPR C-band and NEXRAD S-band polarimetric radar measurements collected during the Midlatitude Continental Convective Clouds Experiment (MC3E) are used in conjunction with 3-Doppler wind analyses. Features described in other studies, such as ZDR and KDP columns, are identified. These features, however, are found to possess structure peculiar to both their respective large-scale and cell-scale environments. General trends are found linking distinct polarimetric signatures to the presence of strong updrafts identified by the wind analysis.
