Variations in Raindrop Size Distributions Associated with Diverse Storm Types and Structures
Storms will be classified based on their large scale forcing (e.g., cold front, warm front, tropical cyclone, upper level disturbance, weakly forced, etc.) using surface and upper-air maps and radar and satellite imagery. In addition, precipitation structures will be classified utilizing horizontal and vertical cross sections and statistical distributions of radar reflectivity. Variations in DSDs will be analyzed using these storm classifications to determine how the DSDs vary by storm type. Collocated rain gauges and anemometers will also be used to determine the reliability of optical disdrometer measurements in various rainfall rates and wind conditions. If time permits, DSD anomalies observed by the Parsivel-2 disdrometer for each storm type will be compared to those observed by an (JW) RD-80 impact disdrometer located in southeast Texas, focusing on identifying and comparing cases without deep convection, including shallow convective and non-convective stratiform precipitation structures.
