摘要
应用７１１雷达１９７６—１９８７年６至８月在济南获取的１９１块雹云雷达回波参量资料和山东德州地区平原高炮人工防雹试验基地１９８９—１９９１年６至８月高炮防雹期间用７１１雷达获取的１８次高炮人工防雹作业前后雹云雷达回波资料，分析了高炮人工防雹效果。结果表明，高炮人工防雹作业后雷达回波的最大回波顶高及下降速率。
Based on 191 hail cloud echoes and variations obtained with a 711 radar in Jinan during June to August from 1976 to 1987 and the rader echo during June to August of 1989 1991 operational period by antihail gun in Pingyuan county,Dezhou district,the effect of hail suppression is evaluated.The results show that echo top altitude and its descent rate,bright belt of 0℃ layer and structures of radar echo are all varied obviously after the hail suppression operations.The analysis is aiming at propelling to develop the cause of hail suppression in Shandong provice and making greater contributions to decrease natural disasters.
