APPLICATION OF AIRBORNE HYGROTHERMOGRAPH IN ARTIFICIAL PRECIPITATION ENHANCEMENT

摘要: 为了实时选择达到冰面饱和的区域实施飞机人工增雨作业,在没有安装PMS粒子探测系统的飞机上安装温、湿度计,把不同温度对应的相对湿度达到冰面饱和的阈值作为是否进行播云的指标。通过不同作业效果的两个例子,探讨了机载温、湿度计作业指标与作业环境场的关系。给出飞机播云应具备的环境场,弥补了播云时无定量判据的缺陷。

Abstract: To select real-time ice-saturation regions to implement aircraft precipitation enhancement operation, hygrthermographs were installed on board aircraft that were not equipped with the PMS particle measurement systems. The thresholds at which relative humidity reached ice-saturation levels with varying temperatures are used as indexes for determining it is right for cloud-seeding. Two cases of different operation results are used to discuss the relatioship between aircraft operation indexes with hygrthermographs and environment in which the operation is conducted. Environmental conditions for aircraft cloud-seeding are given and drawbacks that seeding is preformed without quantitative criteria are made up.
