Data used in this work are north pacific ssta, 160 stations precipitation of china, and ncep reanalysis data. main results are as follow : ( 1 ) it is found that a apparent transition of north pacific ssta in later 1970 ' s : eastern and middle - equatorial pacific ssta turns from cold to warm with area extending, and mid - latitude pacific ( west wind drift zone ) turns from warm to cold. during this transition of ssta, different characters also appear in el nino and la nina : before 1976, la nina happens more frequently, and its duration is longer, el nino zone develops from negative ssta in the early stage ; after 1976, el nino happens a little bit frequent and longer with more intensity than before, el nino zone develops from positive ssta in the early stage ; the course of ssta variation has an enso cycle of 2 - 6 years, annual oscillation of 8 - 9 years, and decadal variation of about 22 years
本文採用1950 - 1999年北太平洋
海表溫度（ sst ） 、中國160站夏季降水和ncep再分析的歐亞500hpa高度場等資料，
利用eof 、 svd 、小波分析、合成分析和相關分析等方法，在分析北太平洋
海溫時空分佈特徵的基礎上，著重探討了
海溫異常及其年代際變化對我國東部降水的影響，並對降水、高度場和
海溫三者之間的關系進行了分析，以試圖尋找三者異常之間可能的聯系，主要結論如下： （ 1 ） 1976年前後，北太平洋
海溫經歷了一次明顯的轉變，赤道中、東太平洋
厄爾尼諾
海區由冷轉暖，暖水范圍增大，中緯度西風漂流區
海溫由暖轉冷；在這樣的年代際背景下，
厄爾尼諾、拉尼娜事件在不同的時期也有不同的特徵：在76年前，拉尼娜事件發生頻率高，持續時間長，事件起始於負
海溫距平；而76年後，則是
厄爾尼諾事件發生頻率略高，持續時間長，強度增大，事件起始於正
海溫距平。
