摘　　要：设置于高山迎风坡的碘化银发行器增雨 (雪 )作业 ,其关键是上升气流时段的选择 ,上升气流关系着有效核入云效率。文章分析了碘化银地面发生器增雨 (雪 )作业的可行性和利用天气图、卫星云图。One key technique of precipitation enhancement by AgI generator established at the windward side of the hill is to choose the occurring and lasting time of updrafts,which affect the rate of the valid nuclei into clouds.The feasibility of precipitation enhancement by AgI generator on the ground is analyzed.Using synoptic chart,satellite cloud picture,radar echo,and precipitation parameters,the technique of determining operating opportunity is discussed.
