对影响江浙沿海台风的路径分布、发生频率等进行了系统分析,结果表明：影响江浙沿海的台风来自于西北太平洋和南海,其中90%以上生成于西北太平洋洋面,其余在南海生成。按其对江浙沿海的影响程度分类,得到影响江浙沿海台风的3种主要路径特征。台风主要在每年的5—11月进入江浙沿海,8月进入江浙沿海的台风数达到最大值；台风频数存在5—6年显著周期；21世纪以来进入江浙沿海的台风数逐渐减少,气旋能量逐年减弱。江浙沿海台风南多北少,浙江省(包括上海市)台风登陆次数较多,江苏省受台风影响相对较弱,基本无台风登陆。由于杭州湾附近特殊的水文环境和地形对台风路径的影响,成为奇特的台风零区,其附近基本无台风经过。

A systematic study was carried out on paths and frequencies of typhoons affecting the coastal areas of Jiangsu and Zhejiang provinces. The results show that typhoons affecting the coastal areas of Jiangsu and Zhejiang provinces originate in the northwest Pacific and South China Sea, with more than 90% generated in the northwest Pacific. According to the extent of influence of typhoons on the coastal areas of Jiangsu and Zhejiang provinces, the paths of typhoons can be classified into three types, and their characteristics obtained. Typhoons land in the coastal areas of Jiangsu and Zhejiang provinces mainly from May to November each year, and the number of typhoons reaches its maximum in August. The significant period of typhoon frequency is five to six years. The number of typhoons and the accumulated cyclone energy have decreased since the 21st century. Typhoons along the coastal areas of Jiangsu and Zhejiang provinces are plentiful in the south and scarce in the north, typhoons land frequently in Zhejiang province and Shanghai City, and there is almost no typhoon landfall in Jiangsu province. Due to the influence of the special hydrological environment and terrain near Hangzhou Bay on the typhoon path, an area centered around Hangzhou Bay is a rare area without typhoons, where no typhoon was observed during the study period.
