Abstract : Ongoing studies of the microphysical kinematic and electrical evolution of two convective clouds observed by radar and aircraft during the Convective and Precipitation Electrification Project (CaPE) are reported. A complete life-cycle of cloud evolution from radar first echo to mature phase is documented using reflectivity (ZH) and differential reflectivity (ZDp). Aircraft data from T-28, NOAA-P3, NCAR King Air and Wyoming King Air are in the process of being analyzed for particle type, electric field from field mills and up/down draft. Surface field mills and LLP data give an indication of first cloud-to- ground lightning time and location. Another on-going study is related to multiparameter radar studies of lightning echoes and a triggered lightning event.... Radar, Electrical, Storms, Lightning.
