Abstract: | Detailed analysis is performed of the low-level moisturefields for the 1979--1983 Meiyu periods, showing that the moisturepassages in various rainbands have striking characteristics, and that thesoutherly flow continuously provides moisture for the region in theform of short-period pulses aud the low-level water transportation isdominant in the precipitation. The conclusion drawn in this paper isuseful for operational synoptic analysis. |
