我国夏季降水对太平洋海温年代际变化响应的数值试验

Numerical study on response of summer rainfall in China to interdecadal SST change in the Pacific

利用近 5 0年观测资料对我国夏季降水和太平洋海温进行诊断分析 ,发现两者都具有年代际变化特征。在此基础上 ,利用 L 9R15大气环流模式 ,对太平洋海温暖背景异常情况下的夏季降水进行敏感性数值试验 ,其结果与统计事实基本一致。

WT5BZ]Based on recent 50 years data, the analysis of variations in SST and summer rainfall in China has been done.The results show that both of them have similar interdecadal change.Based on it, we carry out numerical study on response of summer rainfall to the anomalous warm SST background in the Pacific in terms of L9R15 model, and find that the numerical results are in agreement with statistical facts.
