摘　　要：利用浙江省气象观测站的大风和降水数据,分离出对浙江造成灾害的台风引起的降水和大风.利用分离出的数据统计分析了对浙江形成灾害的台风引起的大风和降水的时空分布规律.研究表明:对浙江造成灾害的台风呈增加趋势,且其引起的大风和降水的程度为9月>8月>7月;灾害台风过程中引起的最大风速主要集中在20～35m/s,影响严重的区域主要集中在沿海区域,西部地区受大风和降水影响较小.The data of wind and precipitation was picked out using the data of meteorological observa- lions in Zhejiang province. The time-space characteristic of wind and precipitation was analyzed based on the data which was picked out. The result show that： The typhoon caused disasters in Zhejiang has increased trends in number; The wind and precipitation of the typhoon which caused disasters in Zhe- jiang in September is heavier then August, and the July is the slightest in the three months. Then maximum wind speed caused by the typhoon are mainly concentrated in 20~35 m/s. Areas severely affected by wind and rainfall concentrate in coastal part, whereas western regions are less affected.
