摘　　要：针对2003年7月8日吉林省境内一次积层混合云人工催化响应过程,确定人工增雨效果检验的背景区和催化响应区,分析云系人工增雨的可播性及背景区与响应区云的微物理量差别。结果显示:(1)催化响应区中冰粒子数浓度明显高于背景区,其中直径为37.5~187.5μm的冰粒子数浓度增加最多;(2)催化响应区中直径小于等于18.5μm的小云粒子数浓度低于背景区,而直径为18.5~45.5μm的大云粒子数浓度则相反;(3)催化作业后,过冷水含量减少,雷达回波强度增加,强回波区范围增大,此次人工催化作业催化响应明显。In order to study physical response of cloud seeding,the precipitation enhancement experiment of stratiform and embedded convective cloud on 8 July 2003 in Jilin Province was analyzed in this paper.The background area and response area of cloud seeding for artificial precipitation enhancement effect were identified,and the seedability of cloud was studied.The differences of cloud microphysical characteristics between background area and response area was analyzed.The results are as follows:(1)The ice crystal number concentration in response area was significantly higher than that in the background area.In response area ice crystal number concentration with a diameter from 37.5μm to 187.5μm increased obviously.(2)The number concentration of small cloud particles with a diameter less than or equal to 18.5μm in response area was lower than that in the background area,but the number concentration of large cloud particles with a diameter from 18.5μm to 45.5μm in response area was higher than that in the background area.(3)After cloud seeding,supercooled water content decreased,the radar echo intensity increased,and strong radar echo zone also increased.The physical response of cloud seeding was obvious in this experiment.
