| 摘 要： | 根据人工触发阀电后雨量猛增的观测事实，利用一个简单的静电模式计算了闪道附近雨滴的重力碰并增长，结果指出，闪电后降雨猛增必须满足一定的条件，除了要求较高的离子浓度（〉１０＾１４／ｍ＾３）外，还取决于闪电所引起的电场变化和闪电被触发后闪道附近环境电场强度的特性。

| Abstract: | In this paper,based on the measurement results of precipitation increasing abruptly after a artificially triggered lightning,gravitational collision efficiency of raindrop near the channel of lightning was calculated by using a simple electrostatic model The results indicate that lightning can produce the rain gush under certain condition Higher ion density(>10 14 /m 3 ) is needed Meanwhile,it depends on the electric field change caused by lightning and electric field intensity near the channel of lightning before triggered lightning |
