增雨飞机“一字线型”作业效果检验分析

Test and Analysis on Effect of Rainfall Enhancement by Aircraft with "One-Character Line" Operating Mode

辽宁省人工影响天气办公室专家为朝阳飞机增雨作业设计方案,在降水云系运动方向的上游,采用"一字线型"作业方式,控制飞机在-4^-7℃冷云云层间,往返播撒碘化银催化剂,并在实际作业中实时调整飞机增雨作业速度、高度。在2019年5月19日降水天气过程中,按照此类设计方案实施飞机增雨作业,通过全市自动雨量站实际降水量检验,取得了较好的增雨效果。

Experts from Liaoning Provincial Office of Weather Artificial Impact designed a scheme for Chaoyang aircraft rainfall enhancement operation.In the upstream of the movement direction of precipitation cloud system,a "onecharacter line" operation mode was adopted to control the airplane to sow silver iodide catalyst between cold clouds at-4--7℃,and to adjust the speed and height of the airplane’s precipitation enhancement operation in real time. In the process of precipitation weather on May 19,2019,airplane precipitation enhancement operation was carried out according to this design scheme. Through the actual precipitation test of Chaoyang automatic precipitation station,the effect of precipitation enhancement was good.
