新疆托克逊1961~2010年气温变化特征分析

Characteristics of Temperature Change at Tuokexun Station in Xinjiang Province from 1961 to 2010

摘要: 利用新疆托克逊国家一般气象观测站1961~2010年的资料，采用气候倾向率和相关分析方法，对托克逊气温变化特征进行了分析。结果表明：托克逊年平均气温、年平均最高气温、年平均最低气温都呈增温趋势，年平均最低气温增温比年平均最高气温增温更明显，年平均最低气温对年平均气温的影响要大于年平均最高气温；四个季节的季平均气温、季平均最高气温、季平均最低气温、季极端最高气温、季极端最低气温均呈现增温趋势，而且秋冬季增温比春夏季更显著；白天和夜间的气温都呈上升趋势，但夜间的上升幅度比白天高近一倍。

Abstract: Based on the data of Tuokexun National Meteorological Observatory in Xinjiang from 1961 to 2010, the climate trend rate and correlation analysis method were used to analyze the characteristics of temperature change in Tuokexun. The results show that the annual mean temperature, annual mean maximum temperature and annual mean minimum temperature all show a warming trend, the annual mean minimum temperature increases more obviously than the annual mean maximum temperature, and the annual mean minimum temperature has more influence on the annual mean temperature than the annual mean maximum temperature. The seasonal mean temperature, seasonal mean maximum temperature, seasonal mean minimum temperature, seasonal extreme maximum temperature and seasonal extreme minimum temperature showed a warming trend in the four seasons, and the warming in autumn and winter was more significant than that in spring and summer. Daytime and nighttime temperatures showed an upward trend, but the increase at night was nearly twice as high as during the day.
