| 摘要: |
| 本文分析了1951—1980年东亚夏季风的强弱变化及其与我国降水分布的关系,发现夏季风强弱不同的时期,我国降水分布有明显差异。同时研究表明,随季风强弱的变化,相应的行星尺度环流亦发生明显改变。最后对夏季风强弱变化的可能原因进行了讨论. |

| Abstract: |
| The relationship between the summer monsoon intensity in East Asia, defined as the difference of sea level pressure from 110°E to 150°E, 10°-50°N, and the rainfall distribution over China is examined. It is foundthat the rainfall distribution over China varys with the variation of summermonsoon intensity. Meanwhile this analysis shows that the planetary scale circulation is also modified accompanying the variation of summer monsoon intensity. Finally, the possible cause of variation of summer monsoon intensity is discussed. |
