Abstract

Total instantaneous water contents of several intense thunderstorms were calculated from smoothed representations drawn from quantitative radar observations; values typically ranged from 108–109 kg. Rain rates and accumulations were obtained from reflectivity measurements near the surface. The rainfall rates of the storms were about 105–106 kg sec−1 with total accumulations averaging 109–1010 kg. Dimensions and durations of the storms are also given.
