摘要： 我国位于季风气候区域区,季风一直为我国气象学者所重视。但过去由于资料短缺,只能通过一些个例或平均资料的分析来研究我国的季风气候,不能了解季风的变化。目前地面和高空资料,都已连续累积了30多年,因此有可能对季风在近三十年的变化进行研究。

Abstract: Considering the fact that in winter the pressure is higher over the land than that over the sea and in summer the pressure gradient is reversed, the intensities of summer monsoon is designated by summing pressure differences between 110°E (land) and 160°E (sea) from 10°N to 50°N at 10 degree latitude interval, in the summing process, only the pressure differences ≤-5mb were included.
