摘　　要：利用2009年5月9日常规天气资料、卫星云图、多普勒雷达资料及2009年5月9日飞机作业中获取的机载微物理资料，对山西省一次积层混合云降水云系的宏微观结构和降水机制进行分析，研究了积层混合云降水云系的人工增雨、催化条件，找出了合适的催化部位和催化时间。研究表明：2009年5月9日云中存在有利于人工增雨的“可播区”，且云中“可播区”呈不连续分布。Using the conventional observation , satellite cloud images , Doppler radar observation and aircraf! microphysical measurements on 9 May 2009, both the macro - and micro - physical structures of cloud systems and precipitation mechanisms have been analyzed. Conditions of the artificial precipitation were studied, and the optimum seeding location and time was chased down. It concluded that the area beneficial to artificial rainfall seeding existed, and distributing interruptedly.
