摘要: 为了研究近54年来青海湖上游天峻地区气温变化的特点及其规律,利用天峻气象站1961—2014年的气温资料,使用线性趋势、Mann-Kendall突变检验和R/S分析法等方法进行分析研究。结果表明:54年来青海湖上游天俊地区年和四季平均气温、最高气温和最低气温均呈显著的上升趋势,冬季升温最为显著,气温日较差呈显著的下降趋势。最高气温的增温率小于最低气温的增温率,存在着非对称性变化的特点。年平均气温、最高气温、气温日较差分别在1994年、1995年、2000年发生了突变。年和四季平均气温、最高气温、最低气温和气温日较差存在明显的Hurst现象。

Abstract: The paper aims to study the characteristics and law of temperature change in recent 54 years in Tianjun by using the temperature data of Tianjun station in 1961-2014 and the linear trend, Mann-Kendall mutation test and R/S analysis methods. The results showed that in recent 54 years, the annual and seasonal average temperature, the maximum and minimum temperature showed a significant upward trend in Tianjun, and the winter warming was most significant. The diurnal temperature range showed a significant downward trend. The warming rate of the maximum temperature was less than that of the minimum temperature, there existed an asymmetry change. The annual average temperature, the maximum temperature and the diurnal temperature range had mutations in 1994, 1995 and 2000, respectively. And there existed obvious Hurst phenomenon in the annual and seasonal average temperature, the maximum and minimum temperature and the diurnal temperature range.
