厄尔尼诺/拉尼娜事件对山西省南部地区气候的影响
Effects of El Nino/La Nina Events on Climate of Southern Shanxi Province
摘要
Abstract
Based on observed temperature and precipitation data since 1961 in Southern Shanxi Province, the trend and periodic changes of temperature and precipitation in the area, as well as the effects of the E1 Nino/ La Nina（E1 Nino/Southern Oscillation, ENSO） events on the temperature, precipitation, droughts, and floods were analyzed using wavelet analysis. The results show that during the past sixty years, the annual temperature of the area increased at a rate of 0.34 ~C/10 a, while the annual precipitation was decreasing at a rate of 23.4 mm/10 a. The wavelet analysis on the periodic changes indicate that the periods of annual tem- perature in the area were approximately 3, 8, 20, and 25 years and that of annual precipitation were about 3 years and 7 years. Annual mean temperature in the area ascended and annual precipitation decreased signifi- cantly in El Nino years, while showed opposite trends in La Nina years. Draughts occur more often in E1 Nino years, while more floods were recorded in La Nina years. Draughts and floods mainly occur in the con- tinuous E1 Nino years and La Nina years, respectively.关键词
