摘要
作者利用现有的气候资料把我国秋高气爽的天气现象的出现地区、起迄日期和形成原因作一初步的分析,同时还把中国的秋高气爽现象跟北半球其他地区如北美印第安夏季,欧洲的老妇人天气或中欧的秋老虎天气作一粗略的比较;最后,还指出我国秋高气爽天气在8月底9月初的建立和地面层冬季风的来临是同时的,而它的结束则与亚洲南部高空西风急流的建立和夏季风影响的停止是同时的.
In this paper,the well-known phenomena of the so-called high autumn clear weather in China is defined and the regions where it most frequently occurs are also determined.After analyzing the variation of 5-days mean rainfall patterns,the dates of its onset and ending are then given.Meanwhile,it is pointed out that these dates are also the dates of beginning of winter monsoon or retreatment of summer monsoon in the surface layer and onset of westerly jet-stream over SE—Asia or ending of the influence of summer monsoon in upper level respectively.Besides,in comparison the said weather with the Indian-summer in North America and old-women weather in Europe,it is found that there are some dissimilarities among them,especially the difference in the formation factors.
