摘　　要：利用中国东部、南部和北部各5个站点近60年以来的气象观测资料,分析了厄尔尼诺事件对我国东部气温和降水的影响,结论如下:在厄尔尼诺事件的影响下,中国东部大部分地区温度相对常年偏高;厄尔尼诺事件夏秋季对我国东部南方气温的影响大于对北方的影响,春季对北方影响较大,对南方影响较小,冬季厄尔尼诺事件对我国东部气温影响相对较小;在厄尔尼诺事件影响下,春季受降水影响较少,北方地区夏、秋和冬季降水及年降水都偏少,南方地区秋季降水显著增多,东南地区冬季降水也显著增加。Using the meteorological observation data from five stations in eastern and southern China for nearly 60 years,the influence of the EI Nino event on the temperature and precipitation in eastern China was analyzed.The conclusions are as follows:(1)Under the influence of the EI Nino event,eastern China The temperature in some areas is relatively high year-on-year;(2)The impact of the EI Nino event on the temperature in southern China is greater than that on the north.The spring has a greater impact on the north and a smaller impact on the south.The winter EI Nino event has a relatively higher impact on the temperature in eastern China.Smaller;(3)Under the influence of the El Nino event,spring precipitation is less affected,summer,autumn and winter precipitation and annual precipitation in the northern region are relatively small,autumn precipitation in the southern region has increased significantly,and winter precipitation in the southeast region has also increased significantly.
