The precipitation frequencies is analysed according to 1956 ~ 2000 years of rainfall record series in baoding area. the features of distribution of rainfall are detailed evaluated. firstly, the distribution of monthly precipitation is not even. for instance. the annual rainfall amount is about 548mm in whole year, about 80 % of them in summer season. secondly, yearly variation of rainfall is greater. thirdly, the abundant years usually are followed by short years, but the important changes have taken place in the last decades. before 70 ' s the abundant years took the dominant position, from the 70 ' s to the middle of 80 ' s the short years took place more frequently than ever. after the later of 80 ' s, the short years hold the main position. the above knowledge is instructive for guiding the rainwater resources effective utilization
本文利用1956 2000年保定市的長系列降雨資料，對保定市降水量進行了頻率分析、年內變化分析和多年變化分析，明確了保定市降水量年內、年際間的變化情況：保定市降水量年內分配不均，汛期（ 6 - 9月）占年降水量的81 。保定市降水量年際間變化大，豐水年和枯水年交替發生， 70年代以前以豐水年段為主； 70年代到80年代前期降水量豐枯交替頻繁，總的接近於枯水年段； 80年代後期至今以枯水年段為主。這種降水分佈規律對農業生產雨水資源的高效利用具有重要的指導意義。 -

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。 -
