摘要
选用青藏高原16个地面气象站1961~2000年3种气温（平均气温、最高气温和最低气温,代号分别为Tmean、Tmax、Tmin）的逐日观测资料,利用最小二乘法计算气候倾向率和年代际变化,以此对40年间青藏高原四季气温的变化进行了分析,结果表明：春季平均气温和最低气温呈增温趋势,最低气温增幅大于平均气温,增幅分别为0.145℃/10a和0.094℃/10a,最高气温呈下降趋势,幅度为-0.048℃/10a。夏秋冬三季,3种气温都呈增温趋势,且最低气温增幅最大,平均气温次之,最高气温增幅最小。
Based on the daily observation data of three kinds of temperature（average temperature,maximum temperature and minimum temperature,hereinafter referred to as Tmean,Tmax and Tmin）,collected by 16 meteorological stations on the Qinghai Tibet Plateau from1961 to 2000,climate tendency rate and inter-annual variation are calculated by using least squares method in order to analyze the temperature change of Qinghai-Tibet Plateau in four seasons during 40 years.The results show that there is a warming trend for the average temperature and the lowest temperature in spring;the increase rate of the lowest temperature is higher than the average temperatures＇ of 0.145DEG/10 aand 0.094DEG/10arespectively;the maximum temperature decreased by-0.048C/10a;there is also a warming trend for three kinds of temperatures in summer,autumn and winter and the increase rate of the minimum temperature is highest;the average temperature the second and the maximum temperature the third.
