| 摘 要： | 模拟分析了河南南阳一次层状云人工增雨过程的自然云和催化云的微物理过程.结果表明自然云内冰晶含量很少,冰相过程不活跃,消耗水汽较少,大滴形成较为困难,降水效率低,降水强度出现过2次峰值.通过对自然云的模拟分析可以得出合适的催化部位,一般在过冷水含量较大,温度较低,云稳定维持阶段(模拟第52分)开始播撒,催化位置为(18 ...

| Abstract: | The microphysical processes of unseeded and seeded stratiform clouds in Nanyang of Henan province were simulated in this paper.The results indicated that the ice crystal content showed very low in the natural cloud,and because the ice phase is inactive,it is difficult to form big drops,so the precipitation efficiency is also low.The precipitation intensity had presented two peak values.Through the analysis of unseeded clouds we can obtain the appropriate catalytic site.Generally,the occasion that the cold w... |
