【摘要】 利用新疆1959～2000年夏季温度资料,采用滑动平均、最大熵谱、经验正交、线性回归方法,分析天山山区近42年来夏季温度变化的基本特征,并与南疆、北疆进行比较。结果表明:①天山山区在夏季温度的冷暖变化阶段以及最炎热、最凉爽年出现的年份与南疆和北疆不同;②夏季温度空间分布的同向性变化北疆最大,天山山区居中,南疆最小;夏季温度空间反向变化南疆和天山山区较大,北疆较小;③夏季温度的年代际变化趋势不同,天山山区持续增温,北疆波动增温,南疆变化稳定;④三种夏季增温的覆盖范围以最低温度为最广,其增温率天山山区最大,南疆最小,北疆居中。更多还原

【Abstract】 Using summer temperature data in Xinjiang from 1959 to 2000 and the methods of running mean, maximum entropy spectrum, empirical orthogonal function and linear regression, the basic features of summer temperature change in the Tianshan mountainous region for the recent 42 years were analyzed and compared with those in the Northern Xinjiang and the Southern Xinjiang. The results show: ① There was difference in warm-cold periods and years of hottest and coolest summer between Tianshan mountainous region and Southern and Northern Xinjiang. ② The synchronous change in the spatial distribution of summer temperature was most obvious in Northern Xinjiang, the second in the Tianshan mountainous region and the smallest in the Southern Xinjiang. The reverse change in the spatial distribution of summer temperature was greater in the Southern Xinjiang and the Tianshan mountainous region, and less in Northern Xinjiang. ③ Decadal trends of summer temperature change were different for the three regions, continued warming in the Tianshan mountainous region, wavy warming in Northern Xinjiang, relatively stable in Southern Xinjiang. ④ Measured by summer minimum temperature, the warming rate was the greatest in Tianshan, the second in Northern Xinjiang and the least in Southern Xinjiang and.更多还原
