卫星反演产品在一次飞机增雨效果检验中的应用

Application of Satellite Inversion Products in the Effectiveness Testing of an Aircraft Cloud Seeding

利用风云2G静止卫星反演产品,对宁夏一次典型飞机增雨催化作业后云参数变化情况进行了分析。结果表明,经过催化后,作业区的云光学厚度、液态水含量、云有效粒子半径相比对比区均有明显增长,同时作业区云过冷水含量相比对比区在催化后下降较快。从这一结果可以反映,对作业区目标云进行催化后,促进了目标云的发展,加速了目标云过冷水向液态水转化的过程,有利于地面降水的增加。

In this paper,the change of cloud parameters after a typical aircraft precipitation operation in Ningxia was analyzed used FY-2G satellite products.The results showed that after seeding,the optical thickness of cloud,the liquid water content and the cloud effective particle radius of the seeding area all increased obviously compared with the contrast area.At the same time,the supercooled water in the seeding area decreased rapidly after seeding.This result reflects that cloud seeding has promoted the development of the target cloud and accelerated the process of the target cloud transferring from the super cooled water to the liquid water,contributing to the increase of precipitation on the ground.
