摘要
通过对哈密地区6个气象站1960—2008年气温观测数据的统计整理,利用回归分析、求相关和t检验、对比分析等方法,研究了哈密地区季、年气温的变化特征。结果表明:近49 a来,哈密地区气温明显上升,1987年以来上升明显;春、夏、秋三季和年均气温每10 a平均最大值均出现在21世纪初期,最小值多出现在20世纪70年代;季节之间及其与年均气温之间相关明显。
Based on the temperature observational data of six weather stations in Hami area during 1960-2008,using the methods of regression analysis,correlation,t-test and comparative analysis etc.,the seasonal and annual temperature change features of Hami area were analyzed.The results indicated that the temperature of Hami area had increased obviously in recent 49 years,and it has increased significantly since 1987;the maximum values of spring,summer,fall and annual average decadal temperature all appeared in the initial stage of 21st century,and the minimum values almost appeared in the 1970s.The correlation among the temperature of different seasons and annual mean was significant.
