| 摘 要： | 利用1951~1995年气温、降水和台风年鉴等资料, 在划分长江中下游冷、热夏年标准的基础上, 分别统计分析了我国近海台风活动异常和季风雨型特征及其与ENSO的关系.指出, 冷夏年和热夏年我国东部近海台风活动差异显著; 与之相对应的季风雨型同样十分悬殊; 同时赤道太平洋海温SSTA场的配置亦迥然不同.最后给出了遥响应过程图像的物理概念模型.

| Abstract: | By using the data of temperature,precipitation and typhoon year book from 1951 to 1995,the warm and cool summers are defined and identified,and features of monsoon rainband distribution and the abnormal activities of typhoons over the East China Sea as well as their linkages to ENSO are statistically analyzed.The results show that the activities of typhoons and the monsoon rainband distribution in warm summers are very different from those of cool summers .Meanwhile,the SSTA over equatorial Pacific exhibits distinctively contrast during warm summers and cool summers.In addition,the physical concept model about the teleconnection is given. |

| Keywords: | The middle and lower reaches of the Yangtze River Warm summer Cool summer Typhoon Monsoon rainband ENSO |
