摘要
利用武汉ＷＳＲ－８１Ｓ数字化雷达回波资料结合卫星云图和地面中尺度观测资料，分析了１９８７～１９９４年４～９月份发生在雷达有效探测范围内的所有暴雨过程。揭示了云图上不同种类暴雨云团下的数字化雷达回波模式。根据暴雨雷达回波和地面中尺度系统的统计事实，分析了数字化雷达回波的动态运动与地面中尺度系统活动的关系。
With Wuhan digitized radar (WSR-81S) echo data and satellite images and mesoscale surface obervations obtained from April-September of 1987～1994, all heary rain occurrences within effective range of radar observations are analyzed. The digitized radar echo patterns under different heavy cloud clusters are revealed. Based on statistical facts about heavy radar echo and mesoscale surface system, the relationship between digitized radar echo developments and mesoscale surface system and that between digitized radar echo developments and mesoscale surface system activities are analyzed.
