| 摘 要： | 基于新疆过去50a气温和降水时间序列长期趋势的研究结果,结合对1986年及附近时段对全球气候产生重大影响的一系列事件（厄尔尼诺、火山爆发、核电站爆炸事故、温室气体增加等）的分析,探讨了1986年新疆气温和降水出现跳跃式变化的原因.具体表现为：当厄尔尼诺现象发生时,常常出现暖冬、早春,在该现象消退过程,往往降水有所增多;...

| Abstract: | In this paper,the reasons of a jump of air temperature and precipitation in Xinjiang Region in 1986 are discussed based on the 50-a data of air temperature and precipitation in Xinjiang Region,together with a series of events(El Nino,volcanic eruptions,nuclear explosion,etc.) which have significant impacts on global climate around 1986.The following specific representations can be seen often: warm-winter and early-spring when EI Nino occurs and increasing precipitation when EI Nino subsidises.The influence of EI Nino is more obvious in North Xinjiang Region than in South Xinjiang Region.Also the volcanic eruption has some climate consequence.Air temperature decreased when powerful volcano erupted during 1980-1986,while air temperature was higher during a volcano’s calm period(1987-2000).The accident of Chernobyl in 1986 caused the world-range consequence;the accident released large numbers of heat,water vapor,mote and radiation that induce the changes of the underlying surface,aerosol and radiation.The mushroom growth of industry increases greenhouse gas emission,which results in increasing temperature. |
