摘要
本文在二维完全弹性冰雹云数值模式中，引入冰晶浓度和播撒物质Ａｇｌ粒子的守恒方程，建立了一个二维催化模式，考虑了人工冰核的三种成核机制，即凝华核化（包含凝结一冻结核化）及与云、雨滴的接触冻结核化，模拟了几种不同冰雹云、不同催化方案下的人工防雹催化效果，指出了防雹的最佳催化方案和适宜催化作业的冰雹云条件。
two-dimensional fully elastic numerical model of hailstorm Seeding indudingice Crystal concentration equation and seeding material (AgI particles)equation has been developed. Three nucleation mechanisms of artificial ice nuclei are described, which are deposition nucleation (including condensation-freezing nucleation),contact freezing nucleation - Brownian and inertial impact collection due to cloud droplets and raindrops. The seeding effects on hail suppression with various hailstorms and seeding methods are disctlssed. Results indicate the suitable conditions for hailstorms seeding and suitable seeding method.
