【摘要】 本文给出了适用于全国的夏季风指标和区分夏季风强中弱和中断期的合理的定量标准。 我们选用23个指标站22年(1961—82)资料研究了中国夏季风的特征。结果表明中国夏季风的进退是很有规律的,且与各地区的雨季开始和结束相一致。并得出夏季风愈强,则降水量也愈大。最后得出夏季风振荡不仅有准两周和准40天周期,而且还存在准3年和准11年周期。更多还原

【Abstract】 This paper suggests an index of the onset and the end of the summer monsoon over China and some reasonable quantity standards suitable for all over China, which distinguish the summer monsoon into strong, medium, weak and break periods.By using the data of 23 stations over 22 years(1961-82),the characteristics of the summer monsoon over China are studied. The results show that the advance and retreat of the summer monsoon are very regular and coincide with the beginning and the end of the rainy season of the different regions of the country. It is also shown that the stronger the summer monsoon, the greater the rainfall. Finally, it is found that not only quasi-2-weak and quasi-40-day periods but also quasi-3-year and quasi-11-year periods exist in the summer monsoon oscillation.更多还原
