摘要
对1983—1986年6—7月在江淮流域间发生的7次暴雨,用平滑滤波尺度分离法,制作了梅雨期次天气尺度天气图。本文重点讨论暴雨在次天气尺度天气图上的分布特征,并进行了物理量场诊断分析,目的在于揭示大尺度背景条件下,与暴雨落区可能有联系的某些次天气尺度扰动。
The Sub-synoptic weather charts are prepared by means of the smooth filtering wave scale separation for the seven heavy rain events occurring over the Changjinag-Huaihe River reaches in June-Julv of 1923 to 1986. The Paper is emphasized on the distributive features shown on the charts and the analysis is made for the phvsical quantities in the prognoatic field. This study has been proved of much helpful in forecasting the heavy rain locations.
