一次冰雹云过程及其催化试验的数值模拟分析

本文应用中科院大气所建立的三维完全弹性冰雹云模式，对2000年6月9日发生在江苏射阳地区的一次冰雹云过程及其催化试验进行了数值模拟，根据模式输出的高时空分辨率资料，分析了冰雹云发生发展过程中的热力和动力场作用及微物理过程的变化，对这次冰雹云形成的机制作了初步分析，并作了一系列碘化银催化试验，对催化防雹的物理机制又进行了较为深入的探讨。

ANALYSIS ON ONE COURSE OF HAIL CLOUD AND CATALYTIC TEST BY NUMERICAL SIMULATION

One course of hail cloud and catalytic test occurred in Sheyang of Jiangsu on 9 June 2000 were simulated by three dimensional numerical model for hail cloud established by Academy of Science of China. We analysed the heat and dynamical effects and micro-physical variations in the course of hail development, and the reasons of hail formation was discussed. Furthermore, we make some experiments about catalytic test by AgI,so we could probe into the physical reasons for catalytic and hail suppression.
