飞机人工增雨作业效果分析

Analysis on Artificial precipitation effect aircraft

采用2009年12月～2010年1月广西飞机人工增雨作业数据,结合作业期间的相关气象资料,分析飞机人工增雨作业效果。结果表明,在影响广西的天气系统总体偏弱的情况下,实施飞机人工增雨作业后,雷达回波强度出现明显增强,降雨明显增加,降雨实况均比常年同期偏多,偏多程度在1成～2倍以上。

Based on the precipitation and radar measurement and other related data,a comprehensive analysis was made on the seeding effects by aircraft in Guangxi during December 2009-January 2010.The results show that continuous precipitation occurred while the radar reflectivity leaped evidently after the cloud seeding.The total amount of precipitation is 10%-200% more than that of the historical same period.It＇s feasible for proceeding weather modification operation by aircraft during the fall and winter time.
