摘　　要：１９９６年８月４—５日北京地区的暴雨是台风低压、副热带高压和切变线相互作用的结果。暴雨前存在从华中伸向华北的高能舌，北京能量激增，偏南低空急流不仅为暴雨区输送了水汽、能量，急流中的风速脉动还触发了湿有效能量的释放。Based on hourly precipitation data of Xiamen,Anxi,Jiuxianshan and Youxi from May to June during 1970_1994,statistic calculation and contrast analysis are conducted,the climatic features of short period precipitation and its condition under different terrains during rainy season in south Fujian are revealed,the results are useful and valuable in nowcasting and service.
