Identify each contiguous 3D “Storm” Storm Classification Identify each contiguous 3D “Storm” seen by TRMM PR Convective component Stratiform component Extreme characteristic Contiguous 3D volume of convective echo > 30 dBZ Top height > 8 km “Deep Convective Core (Deep)” Horizontal area > 800 km2 “Wide Convective Core (Wide)” Contiguous stratiform echo with horizontal area > 50 000 km2 “Broad Stratiform Region (Broad)” “Isolated shallow echo (Shallow)” Echo top > 1 km below freezing level and separate from deeper convection
