中文摘要: 以中国大陆1951—2003年160站的月平均气温资料为基础,利用Mann-Kendall突变检验法和滑动t检验法重点对中国大陆地区气温突变的区域特征和季节特征进行了探讨。得到以下结论:近55a来,中国大陆地区变冷区域显著缩小,变冷区域的变冷趋势明显减弱;东北、华北区域年平均气温在20世纪80年代中后期发生突变,西北、中南区域年气温在20世纪90年代前期发生了突变;同一区域气温发生突变时,冬季气温突变时间较春、夏、秋季节均偏早。
Abstract:Using Mann-Kendall jump test and moving t-test, the temperature change features in China in recent 55 years are analysed based on the data of monthly mean air temperature from 160 stations in 1951—2003, with a focus on the analysis of the regional and seasonal features of abrupt temperature change. It is found that (1) since the 1950′s the cooling regions became smaller and the trend weaker;(2)the sudden changes are observed in Northeast China and North China in the last 1980′s;(3)the jump change in winter was earlier than the other seasons in the same area.
