摘　　要：应用 1 94 9～ 2 0 0 0年台风、降水、历史天气图等资料 ,对发生在华北地区的台风暴雨进行统计研究 ,得到了其时空分布、登陆地点、移动路线、季节特征以及与中纬度系统相互作用的关系。结果表明 :52年中 ,由台风引起的暴雨共 51次 ,平均约每年 1次 ,且主要出现在夏季 (尤以 7、8月最多 ) ;影响华北的台风登陆地点以及移出或消失地点具有明显的特征 ,福建、浙江沿海登陆次数最多 ,江苏北部到山东南部没有台风登陆 ,而这一地区为台风移出最多区域 ;登陆台风强度较强时 ,出现较大降水的概率大 ,而台风强度较弱时造成较大降水的概率相对较小。Based on the data of typhoon and precipitation and history weather maps from 1949 to 2000, statistical analysis of typhoon heavy rain in North China is made, it is found that lots of characteristic about typhoon of time-space distribution, landing area, moving route, seasonal feature and the interaction between typhoon and mid-latitude system. It shows that in 52 years, there are 51 heavy rainfall events resulting from typhoon, about 1 event a year. Most of them occurred in the summer (July and August). When typhoons made landing, or disappear, the locations were very regular, and the landing places were mostly in Fujian, Zhejiang. There is no typhoon landing between northern Jiangsu and southern Shandong where typhoon goes out mostly. When a typhoon is very strong, appears easily. On the other hand, when a typhoon is very weak, there would be little precipitation.
