In this paper, decadal variability of tropic and north pacific ' s ssta and of precipitation in china, correlations between them and the possible mechanisms of the ssta decadal change compacting on the precipitation decadal change are analyzed by using ncep globe temperature, wind and height data ( 1948 - 2001 ), coads ssta data ( 1900 - 2001 ) and 147 stations " precipitation data in china. results show that : ( 1 ) mid - high latitude north pacific and tropic west pacific ssta have obvious decadal change, the prior ' s decadal change has great variance and the latter ' s has great contribution in total variance, the main eigenvectors " distribution are stable in eof of tropic and north pacific ssta ' s decadal variability, the key area of the first eigenvector allots in two sides of tropic pacific ; the second one ' s allots in mid - high latitude northwest pacific and low latitude mid - east pacific which vary contrary ; the third one ' s allots in middle north pacific
本文利用ncep資料（ 1948 - 2001年）中的全球表面溫度場、風場、高度場資料， coads （ 1900 - 2001年）海表面溫度距平資料及中國147個站點1951 - 2001年共51年的降水資料，探討了熱帶及北太平洋ssta 、中國降水的年代際變化特徵，夏季熱帶及北太平洋ssta年代際變化與中國夏季降水年代際變化的耦合相互關系以及夏季熱帶及北太平洋ssta年代際變化影響中國夏季降水年代際變化的可能機制，結果表明： （ 1 ）北太平洋中高緯與熱帶西太平洋均有明顯的年代際變化，北太平洋中高緯年代際變化方差顯著，而熱帶西太平洋年代際變化方差貢獻顯著。 -
