摘要
为选择飞机人工增雨的作业区和作业时机 ,利用中尺度模式、加密探空和PMS粒子探测系统的资料 ,分析了江淮气旋冷锋共同影响降水过程中的宏微观结构、适宜冷云云中冰晶增长的区域和可播区。结果表明 ,可以在降水前的水汽由低层向高层输送和冰晶增长区由高层向低层传播的过程中选择作业时机 ,在上升速度区、- 1 0℃层云水高值区和冰水转化区等区域中选择作业区。
For selecting operation location and time, the macro-micro structure of Jianghuai Cyclone cold front as well as ice crystal growing and cold cloud seeding fields are analyzed using a mesoscale model, additional sounding data, and PMS data. The operation location can be identified according to the process of vapor transportation from low to high and the propagation process of ice crystal growing fields from high to low before precipitation. The seeding field can be determined according to the areas with ascending air and high cloud water value in the -10 ℃ layer and the area where ice-water conversion occurs.
