摘要
利用呼和浩特市近61年平均气温序列资料,通过描述统计、趋势分析、Mann-Kemdall突变检验方法对呼和浩特市气温变化特征进行分析。结果表明,1954年以来,呼和浩特市年平均气温总体呈上升趋势,变化速度约为0.5℃/10 a,尤其进入20世纪90年代增温趋势明显加快;冬季升温对全年升温贡献最大;20世纪80年代中期气温发生了由冷向暖的突变。
Based on the monthly temperature data from 1954 to 2014 in Hohhot,the characteristics of Hohhot temperature variation have been analyzed by use of descriptive statistics,trend analysis and Mann-Kemdall abrupt change test. The results show that the annual average temperature in Hohhot has risen on the whole since 1954,and the changing rate is about 0. 5℃ /10 a. Especially in the 1990 s,the warming trend accelerated. The warming in winter made the largest contribution to the annual temperature. And the abrupt change of temperature from cold to warm had happened in the mid-1980 s.
