摘要
利用了74项环流特征量资料、1951年1月～2003年12月我国160站月平均降水资料，通过相关分析以及t检验的方法，研究了西太平洋副高与我国夏季长江中下游地区降水的关系。结果表明，夏季长江中下游地区降水与副高的脊线位置之间有显著的负相关关系，与副高的面积指数之间有显著的正相关关系，且相关系数均通过了0．05信度检验。
Based on 74 characteristic indexes of circulation, monthly average precipitation data of 160 stations in China during Jan. 1951-Dec. 2003, the relationship between Western Pacific subtropical high and summer precipitation in the middle and lower reaches of Yangtze River was studied by correlation analysis and t-check. The results showed that the summer precipitation in the middle and lower reaches of Yangtze River is negatively correlated with the location of the axis of ridge high respectively. However, it has a significant positive correlation with the size index of the subtropical high separately, and the related coefficient is proven by 0.05 reliability test.
