【Abstract】 In order to understand a heavy rainstorm process over South China in 19 -22 May 1987, only we be analyzed synoptic environment and false colour satellite cloud maps’ features in mesoscale ccnyective rainfall distribution in the Pearl River Delta in this paper. At the same time, we can make some physical features of mesoscale convective rainfall by band-pass filter method, and its effect on the rainstorm.更多还原
