MOISTURE SOURCE AND TRANSFER IN THE MEIYU CLIMATIC REGION OF THE MID-LOWER CHANGJIANG RIVER
Abstract:Detailed analysis is performed of the low-level moisturefields for the 1979-1983 Meiyu periods, showing that the moisture passages in various rainbands have striking characteristics, and that the southerly flow continuously provides moisture for the region in the form 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.
