【摘要】 本文应用平滑滤波方法，分离1984年9月1日08时及20时（北京时）台风暴雨中天气尺度和次天气尺度系统，计算及分析这两种尺度系统之间，两个时次、不同层次及整层积分的位势转换量I、水平位势转换量IH、垂直位势转换量IV，得到了一些有益的结果。更多还原

【Abstract】 Emplying the method or smoothing and filtering, the synoptic and sub-synoptic Scale systems in typhoon rainstorm at 08 and 20 hour (Beiging time) on September 1st., 1984 were separated. Some beneficial results are obtained after computing and analyxing the quantities of potential conversion I, IH and IV between these two different scale systems, times and leayers更多还原
