摘要:

利用近60 a中國160站夏季降水資料和NCEP/NCAR月平均位勢高度場、風場等再分析資料,采用相關分析和合成分析等方法對東亞太平洋遙相關型(EAP)和歐亞遙相關型(EU)的不同配置特征及其對中國夏季降水的影響進行了研究。研究結果表明:EAP與EU兩種遙相關型是相互獨立的,相關系數(shù)為-0.03。兩者存在以下四種配置:EAP和EU均活躍且位相相同(第I類配置)、EAP和EU均活躍且位相相反(第II類配置)、僅EU活躍(第III類配置)和僅EAP活躍(第IV類配置)。EAP與EU呈現(xiàn)不同配置類型時,中國夏季的降水分布相應的存在差異。當二者之間是第I類配置時,降水異常分布呈北方型;當二者配置為第II類時,降水異常分布呈現(xiàn)出中間型,雨帶集中在長江流域;第Ⅲ類配置時,降水大值區(qū)主要集中在長江中上游黃河以南地區(qū);而第Ⅳ類配置時,降水集中在長江中下游地區(qū),雨帶呈東北—西南走向。

Abstract:

Based on the monthly summer precipitation data of 160 stations in China and NCEP/NCAR monthly reanalysis datasets, the summer precipitation distribution in China was examined using correlation and composite analysis. It was found that the East Asia Pacific Teleconnection pattern (EAP) and Eurasian Teleconnection pattern (EU) are independent of each other with a correlation coefficient of -0.03. There are four configurations between EAP and EU: (Ⅰ) both are significant and in phase; (Ⅱ) both are significant but out-of-phase; (Ⅲ) EU is dominated and (Ⅳ) EAP is dominated. The rainfall distribution becomes different with the configuration. When configuration Ⅰ exists, the area of anomalies of summer rainfall is in the North of China. When the configuration belongs to Ⅱ, the rainfall anomalies show medium, which means the rainfall will be unusually greater in the Yangtze River. When the EU is dominated, i.e. configuration Ⅲ exists, most of the rainfall appears in the upper and middle reaches of the Yangtze River as well as the southern region of the Yellow River. However, during configuration Ⅳ, i.e. the EAP is dominated, the middle and lower reaches of the Yangtze River become the rainfall anomaly areas. The rain belt presents northeast-southwest direction.
