Abstract：Based on the hourly precipitation data of Guangxi meteorological observation station and the SRTM 250 m digital elevation model data of the United States,this paper defines the extreme short-duration precipitation events in Guangxi and analyzes their characteristics.The close relationship between the spatial distribution characteristics of extreme short duration precipitation and terrain in Guangxi is revealed.The monthly variation characteristics of extreme short duration precipitation in Guangxi are analyzed.And the relationship between extreme short duration precipitation in Guangxi and the establishment and retreat of South China Sea summer monsoon is discussed.The research results provide a fine decision about reference for short duration precipitation forecast and early warning in Guangxi.
