摘要
本文通过整理阿拉善右旗1969-2018年气温逐年气象观测资料,对阿拉善右旗平均气温年际变动、季节性变化趋势、突变特点展开研究。结果表明,50 a中右旗温度呈0.39℃/10 a的速度增加,在20世纪90年代之后增温明显,且有显著的阶段性波动特点。季节性气温都是以不同速度在增加,春季平均气温增加发展趋势在四季中极为明显。由最高气温季节平均值可知,春季最大,其次为秋季、夏季、冬季。由此可知,最低温度季节性均值是春季最大,其次夏季、秋季、冬季。年和四季平均最低气温的增加波动,使得平均气温日较差呈减小态势。
This paper studied the interannual changes,seasonal trends and sudden change characteristics in the average temperature of Alashan Youqi by collating the annual meteorological observations of the temperature in Alashan Youqi from 1969 to 2018.The results showed that the temperature of Alashan Youqi increased at a rate of 0.39 ℃/10 a in 50 years,the temperature increased obviously after the 1990 s,and it had obvious characteristics of periodic fluctuations.Seasonal temperatures increased at different rates,and the increasing trend of average temperature in spring was extremely obvious among the four seasons.According to the seasonal average of the highest temperature,the average maximum temperature in spring was the highest,followed by autumn,summer,and winter.From this,it′s indicated that the seasonal average of the minimum temperature was the highest in spring,followed by summer,autumn,and winter.The increase and fluctuation of the average minimum temperature of the year and the four seasons made the daily temperature difference decreased.
