摘　　要：广州市的大暴雨灾害与暴雨的强度、时空分布以及广州的地势等密切相关。大暴雨灾害主要出现在夏半年4～9月的汛期中,其中4～6月的大暴雨大部分是由冷空气南下与热带暖湿气流共同作用引起的,只有少数几次是由热带气旋影响产生的;而7～9月大暴雨主要是热带气旋和热带辐合带等热带系统形成的。The disaster from heavy rainstorm in Guangzhou is correlated with intensity and temporalspatial distribution of rainstorms and the topography of this district The rainstorm disasters mainly occur in flood season form April to September Most of heavy rainstorms are caused by the interaction of cold air and warm air mass from April to June and a few of them are originated from tropical cyclones Rainstorms from July to September are resulted mainly from tropical cyclones and climate in intertropical convergence zone 
