摘要
作者对１９８６年至１９９３年５—９月区域性暴雨发生前５００ｈＰａ散度场进行定量分析，找出预报关键区和指标，提出预报信号；再查找天气型指标，确定是否预报；最后用低层物理量指标估计降雨量级。
ivergence fields are quantitatively analysed before regional torrentical rain process from May to September, 1986 to 1993. And therefore key area and indexes are found for the forecast message of torrentical rain. Researches on weather-map type indexes were conducted in order to get the answer of the appearance of torrentical rain. The estimation of the classification of rainfall has been done according to physical quantity indexes at lower layer of atmosphere.
