| 摘 要： | 利用IAP三维云模式对2005年7月一次强暴雨过程上游的水汽通量进行了人工影响试验．模拟和分析发现，AgI播撒速率的选择对增雨效果影响较大，仅当播撒速率在0．07g／s以下时才有增雨效果；过冷云水发展到极大值时，以0．05g／s播撒AgI获得的增雨效果最好，播撒过程使得自然云内的冰晶和雪晶出现的时间提前，含量明显增加。

| Abstract: | Modification of upstream water vapor flux of a rainstorm in July 2005 was simulated to change the intensity of downstream precipitation by using the IAP 3-dimension cloud model,and the conditions and means of weather modification were analyzed.Results show that the seeding rate has close relationship with the effect of precipitation enhancement: the effect can not be seen only when the seeding rate is below 0.07g/s.At the same time,it is also found that the best effect appears when the super-cooled water reaches the maximum value and the seeding rate of AgI is 0.05g/s.Seeding makes the ice and snow crystal in the natural cloud appear earlier,and the content increase evidently. |
