| 摘 要： | 本文用1951—1980年中国和印度的降水资料研究了两个地区在西南季风时期(6—9月)总雨量变化的关系。发现印度的雨量变化与中国各地雨量的相关关系有正、有负,最明显的是印度中西部与我国华北地区有较高的正相关。进一步对两个地区降水存在遥相关的原因进行了分析,发现南亚次大陆低压是联系两个季风区雨量变化的重要环节。中国季风雨量与印度季风雨量的相关趋势,主要决定于中国各地雨量与东亚夏季风强度的关系。

| Abstract: | The relationship between Chinese and Indian summer (June to September) monsoon rainfall is examined using a data set available from 1951 to 1980. The structure of the large scale circulation which linked together the rainfall making processes in these two regions is analyzed. The main results are as followed:1. The correlation coefficients between the summer monsoon rainfall in China and India are calculated. The maximum of positive correlation is found between Indian rainfall and rainfall in North China. A secondary maximum of positive co-relation is located in the region from the upper reaches of the Yellow River to the western part of Sichuan province, but the area with significant correlations is not as large as in North China. In western China, including the Tibet and Xin Jiang, negative correlations are predominated. However, the rainfall along the Yangtze River valley, especially in the middle and lower reaches, where the Meiyu usually occurs, the correlation coefficients remain small.2. The analysis of the two teleconnected regions shows that the hot low over South Asia plays an importent role, because its intensity is resposible for the variations of the summer monsoon intensity over both India and East Asia. As the summer monsoon regulates rainfall making processes, a close connection is found between the rainfall in India and China.3. The correlation coefficients between the summer monsoon rainfall over the whole India and the regional rainfall in China vary from positive in one Chinese region to negative in another, because the relationship between the intensity of East Asia summer monsoon and the rainfall in different places over China also varies from one region to another. As the correlation between summer rainfall and the intensity of East Asia summer monsoon is strong the regional rainfall in china is closely correlated with the Indian summer monsoon rainfall. |
