【摘要】 利用戈达德太空研究所(Goddard Institute for Space Studies,GISS/NASA)建立的全球网格点月平均地表温度距平序列,通过一元线性回归、M-K检验对中亚地区1880～2011年地面气温变化的基本特征进行分析和讨论。结果表明:近130 a来,中亚地区温度变化趋势率为0.073℃/10 a,接近于全球,高于我国的近百年温度变化趋势率;中亚地区1、4、10月呈增温趋势,其中1月份温度变化幅度最大,4、10月份增温趋势率较大;而7月份呈微弱降温趋势。中亚地区年平均温度在20世纪80年代初期发生突变,出现较大的增温趋势,尤其是近50 a,增温明显。更多还原

【Abstract】 Based on the global grid point monthly average surface temperature anomaly sequence established by the Goddard Institute for Space Studies(GISS/NASA),the basic characteristics of the surface temperature change in central Asia from 1880 to 2011 were analyzed and discussed by using linear regression method and Mann-kendall test.The results show that in recent 130 years,the temperature increased with a rate of 0.073℃/10 a in central Asia,which was similar to the global level and more than Chinese level.In January,April and October,temperature in central Asia presented increasing trend,and in July,it presented a weak decreasing trend.The annual average temperature in central Asia had the abrupt change in the early 1980s,especially in recent 50 years temperature increased obviously.更多还原
