中文摘要: 利用所计算的1961～1995年高原热源资料、四川与重庆的降水资料以及500hPa月平均高度场资料,分析了高原地表热源异常对四川盆地降水与旱涝的影响。结果表明,高原地表热源异常与四川盆地降水和旱涝有显著的相关;高原地表热源异常通过强迫500hPa东亚大气环流异常来影响四川盆地降水。
中文关键词: 青藏高原，地面加热，四川盆地夏季降水，相关分析
Abstract:Based on the data of heating resource, and the rainfall in Sichuan Province and Chongqing City, the relationship between the surface heating fields over the Plateau and the precipitation in Sichuan basin during summer is analyzed. The results show that (1) There are obvious correlations between the surface heating over the Qinghai Xizang Plateau and the precipitation in the Sichuan basin during summer. (2) The anomaly of the surface heating fields over the Plateau, which is forced by the anomaly of 500hPa circulation field over East Asia is able to affect the rainfall in the Sichuan basin during summer.
