中文摘要: 利用GPS仪和新一代天气雷达的探测，对广西2008年2月16日一次飞机人工增雨作业的效果进行了物理检验。分析表明，对过冷云实施播云作业后，过冷云层的微物理影响能直接导致高层过冷水与冰晶混合区以及低层暖区云雨层对雷达基本反射率的增强，同时能比同等条件下非催化云层更快到达雷达回波峰值，并持续较长时间。催化作业可使冷层的雷达回波增强最大可达200%，同时可使低层暖区云雨层的雷达回波增强最大可达100%。

Abstract:In order to augment the precipitation on the ground, cloud seeding experiments have been carried out for more than 60 years. However， it remains to be very difficult to evaluate the seeding effect because of the large nature variations of the cloud. By the use of GPS and CINRAD techniques, a physical test was made for the operation of weather modification in Guangxi on 16 February, 2008. It shows that after the cloud seeding, microphysical changes in the supercooled clouds may lead to the enhancement of the basic reflectivity on radar in both of the supercooled cloud layer and the warm cloud and rain layer, and be more quickly in reaching the maximum value than the non operated clouds which are under the similar conditions, and last for a longer period. After the cloud seeding, the maximum enhancement rates of the echo reflectivity in the supercooled cloud layer and in the low and warm region may reach 200% and 100%, respectively.
