Abstract: The relations between synoptic situations of winter successive precipitating days in south - eastern China and high level circulation of southern hemisphere or low latitude wereanalysed. It appeared that the northwars conveyance of longitudinal wind, turbulent momentum and heat flux. Which are related tothe latitudinal distribution and warming effect of temperature field, combined with divergence current aloft had much influences to promote the successive precipitating days weather in south eastern China.They are the driving forces to enchance thesubtropic jet stream and frontal zone of eastern Asia and push them northward.
