摘要
文章利用广西气象观测站逐小时降水资料和美国SRTM 250 m地形数字高程模型数据,定义广西极端短历时降水事件并对其特征进行探究分析,揭示了广西极端短历时降水空间分布特征与地形的密切关系,分析了广西极端短历时降水月变化特征以及探讨了广西极端短历时降水与南海夏季风建立和撤退的联系,研究结果为广西短历时降水预报预警提供了精细的决策参考。
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.
