| Abstract: | 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. |
