| 摘 要： | 统计分析了1980～1999年辽宁人工增雨示范区内5～10月各类降水云系产生不同强度降水的降水次数和降水量特征。结果表明:降水时长与其相对应的降水次数呈反比关系,降水时长越长,其相应的降水次数越少;而降水时长与其降水量的分布则呈不规则的波动;降水时长为2～8 h的降水量对总雨量的贡献为66%,是实施人工增雨作业的最佳时段。

| Abstract: | The frequency and characteristics of different intensity precipitation caused by all kinds of clouds were analyzed in the demonstration region of artificial precipitation enhancement in Liaoning Province during May to October from 1989 to 1999.The results showed that the precipitation duration had a negative exponential function relationship with corresponding precipitation frequency.The longer the precipitation duration was,the less the precipitation frequency was.The precipitation duration and precipitation distribution showed an irregular fluctuation.The 2-8 hours precipitation duration in which the precipitation accounted for 66% to total precipitation was the best period of precipitation enhancement. |
