利用MICAPS资料、卫星反演产品和多普勒雷达产品，采用统计和物理检验相结合的方法，对2010年12月15日重庆主城一次飞机人工增雨作业过程进行了效果分析。分析表明，此次飞机人工增雨作业相对增雨率在20％以上，在云系发展开始和持续发展阶段增雨效果好；雷达回波、卫星反演产品均能反应人工增雨催化前后的物理变化，催化作业后1h内引起的物理变化最为明显。反射率因子图上的零度层亮带是把握人工增雨作业时机和部位的重要依据。

The effect evaluation has been made on the aircraft cloud seeding operation which took place on the 15th ,Dec ,2010 in Chongqing area .MICAPS data ,satellite retrieving images and Doppler radar prod-ucts have been used in the evaluation .T he results show that the relative ratio of precipitation increase is a-bove 20% ,and between the two flights launched for this mission ,the first flight provided a better result than the second one ,proving that seeding operations during the beginning and continuing phases of cloud developing period usually leads to positive rainfall enhancement . Furthermore , the physical changes of clouds before and after seeding can be detected by Doppler radar and daytime satellite retrieving images .A-nalysis show s that changes happen most vigorously an hour after seeding .Also ,the 0° layer bright band on radar reflectivity factor images could be used as an indicator when choosing cloud seeding time and areas .
