摘　　要：利用中国气象局1991—2020年的《热带气旋年鉴》和河源市5个国家气象观测站的日降水资料,总结分析河源市台风暴雨统计特征,结果表明:①1991—2020年,登陆海南东部到福建并对河源造成暴雨的台风共40个,平均每年1.3个,最多的年份有4个;过程平均雨量和暴雨总频次大致都呈南多北少分布;暴雨多出现在登陆当天和登陆后一天。②根据登陆点将河源台风暴雨过程主要归纳为4类:登陆海南东部到粤西、登陆珠江口附近、登陆粤东、登陆福建,其中登陆粤东造成河源暴雨的台风个数最多。③登陆珠江口的台风造成的河源暴雨多发生在南部和西北部;登陆粤东的台风常常自南向北穿过河源,最易造成全市范围的暴雨降水;登陆福建的台风环流自东向西横穿河源时,北部影响时间长,降水强度更强。Using the data from Typhoon Almanac of China Meteorological Administration and daily precipitation data of 5 national meteorological stations in Heyuan City from 1991 to 2020,the statistical characteristics of typhoon rainstorm in Heyuan is summarized and analyzed.The results showed as follows:①During the 30 years from 1991 to 2020,there was a total of 40 typhoons landed between the area of the eastern part of Hainan and Fujian causing rainstorms in Heyuan,with an average of 1.3,and the maximum of 4;the average areal rainfall and the frequency of rainstorm decreases from south to north;rainstorms usually occur on the day of landing and the day after landing.②According to the he landing point,the typhoon rainstorm process in Heyuan could be classified into 4 categories:landing from eastern part of Hainan to the western part of Guangdong,landingin the area near Pearl River Estuary,landing in the eastern part of Guangdong,landing in Fujian,and the number of typhoons landing in eastern Guangdong causing rainstorm in Heyuan is the largest.③The rainstorms caused by typhoon landingin the area near Pearl River Estuary mostly happen in southern and northwestern part of Heyuan;typhoons landing in eastern Guangdong are most prone to cause citywide torrential rain,passing through Heyuan from south to north after landing.When the typhoon circulation passing through Heyuaneast to west after landing in Fujian,rainfall intensity in the northern part of Heyuan is stronger,with a longer impact time.
