| Abstract: | With the use of conventional observation data from 1991 to 1996, composite analysis of the evolutions of the upper and lower levels winds and the upper northeasterly flow during the onset period of Jianghuai Mei-yu was conducted. The comparison between two types of heavy rains is made related to their weather situations, dynamics, and three-dimensional stream fields. Results of the analysis are shown to be useful for the forecast of heavy rains. |
