| 摘 要： | 厄尔尼诺和拉尼娜海洋现象对世界气候的影响非常大,我国东部地处太平洋西岸,降水明显受其影响.本文从1950~1999年50年赤道太平洋中东部海温距平资料入手,得出厄尔尼诺现象和拉尼娜现象50年的表现特征.然后对中国东部夏季降水异常情况进行统计,分析了太平洋海温异常与中国东部降水异常的统计关系.并因此得到El Nino年华北显著偏旱,淮河流域El Nino年出现涝灾的概率达到50%,长江中下游地区出现在El Nino年和La Nina年的旱涝年数相差不大,华南在El Nino年出现的旱年数占全部旱年的50%等一些有意义的结论.

| Abstract: | El Nino and La Nino Phenomena are the oceanic anomalous phenomena that have the great effect on the world climate.East of China is located the western coast of Pacific,the precipitation are sure to be influenced by the phenomena.The paper gets from the information of SSTA in Pacific during the periods in 1950-1999 years,has received the some features of change of El Nino and La Nino events in the periods.Then the paper analyses the statistical relationship between the SST anomaly in middle and east of equatorial Pacific with the precipitation anomaly in east of China,last get some result of significance. |
