  1. Further, correlation analysis is used to the summer rainfall and four seasonal north pacific ssta, the results suggest north pacific ssta which notability cause the summer rainfall anomaly over eastern china are prophase winter ssta of kuroshio region of northwestern pacific, prophase spring ssta of middle and eastern equatorial pacific and summer ssta of west wind drift region

    進一步對上述東部夏季降水異常區夏季降水與春夏秋冬太平洋海溫異常作相關分析,表明對中國東部夏季降水有顯著影響是:西北太平洋黑潮海區前期冬季海溫異常、赤道中東太平洋前期春季海溫異常、中高緯太平洋西風漂流區同期夏季海溫異常。
  2. 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。
  3. The sst anomaly of the equatorial eastern pacific and west wind drift region both have influence on the general circulation and summer rainfall in north china, and the influence is nonlinear, which is not only manifested through the intensity change of anomaly of general circulation and summer rainfall in north china, but also through the spatial distribution pattern of the anomaly

    赤道東太平洋、西風漂流區海溫的異常都會對大氣環流和華北夏季降水產生影響,這種影響是非線性的,這種非線性關系不僅僅體現在大氣環流和華北夏季降水異常的強度變化上,也體現在異常的空間分佈形態上。
