Abstract: The cloud and precipitation processes of mei-yu front rainfall during 25～28 Jun. 1999 in the area of yangtze river have been studied by mesoscale nonhydrostatic numerical model MM5(v2). The nonconvective precipitation are predicted by using the Reisner scheme. With analyses on cloud microphysical processes,especially on source and sink terms of hydrometeors,physical processes of mei-yu front cloud system can be understood clearly.
