| 摘 要： | 利用1961－1995年青藏高原及其邻近地区148个测站的月平均资料，分析研究了高原地面热源与华西秋雨的联系。结果表明，高原东部地面热源与华西秋雨存在着显著的负相关关系。高原东部地面热源异常强迫500hPa大气环流异常来制约华西秋雨的多寡。 |

| Abstract: | Surface heating fields over the Qinghai-Xizang plateau wereestimated using the 35 years(1961—1995) data set of 148 observation stastions in the Qinghai-Xizang plateau and near area, the relationship between the surface heating fields over the plateau and precipitation in the southwest China in autumn is anlysed. The results are as follows: (1) There are negative correlations between the surface heating over eastern part of Qinghai-Xizang plateau and precipitation in southwestern China in autumn. (2) Anomaly of 500 hPa atmospheric circulation over the Asia-Europe forced by abnormal of surface heating over the Plateau is able to restrict amount of precipitation in the southwestern part of China in autumn. |
