| 摘 要： | 本文对1966—1989年6—8月亚洲东部中高纬(45—75°N,80—120°E)阻塞高压活动进行了研究。指出,在这种环流背景下,我国东部地区常出现大范围连续暴雨天气。还利用500hPa东亚(100—120°E)地转风场,探讨了我国主要暴雨带与东亚阻高南侧东风、南支西风急流、中纬北风南界以及低纬最大南风轴之间的相互关系。

| Abstract: | In this paper, the observations of the blocking high over the mid-high latitudes in east Asia (45-75°N, 80-120°E) are analysed. The results show that the continous heavy rains in the east part of China often occurred under the conditons with the blocking high circulation. The relation of the major heavy rain zones with the east wind to the south of the East Asian blocking high or with the south branch of the west jet, or with the south boundary of the north wind over the middle latitudes as well as with the axis line of the maximun south wind in the low latitudes are investigated. |
