摘要
本文利用四川省2010年度飞机人工增雨作业资料,统计每次作业前后雷达回波强度、回波面积、回波高度、垂直累积液水含量等因子的变化情况,分析了适宜作业云系的一些雷达回波统计特征和催化影响的物理效应,得到一些很有意义的结果,为人工增雨作业效果检验和效益评估提供了客观证据,对提高人工增雨作业技术具有一定的指示意义。
In this paper, we used aircraft artificial precipitation data of Sichuan province in 2010 to calculate the changes of radar reflectivity intensity , radar reflectivity area, radar reflectivity height, and vertical accumulation of liquid water content which occured before and after each operation. By analyzing statistical characteristics of the appropriate operating cloud and the physical effects of catalytic influence, it got some meaningful results to provide objective evidence for effect test and benefit as- sessment of artificial precipitation operation. It has some significance to improve the artificial rainfall technology.
