摘要:
 基于1961-2016年内蒙古科尔沁地区12个气象站的日平均温度资料，分析了近55 a来该地区冷暖天数及其过渡期的变化特征。结果表明，1961-2016年内蒙古科尔沁沙地气候变暖趋势明显，其气温突变年份为1988年。在全球气候日益变暖的趋势下，气温突变后在冬季里寒冷以上的天数不但没有显著减少,反而呈微弱上升的趋势，高温增加的天数要明显多于低温减少的天数。科尔沁沙地冷暖、寒冷温暖、严寒炎热过渡期在55 a时间尺度上基本无明显的变化，但在突变前后呈相反的变化趋势，特别是在气温突变以后，科尔沁沙地在冷暖两极的日数明显增多，过渡期变短，冷暖急转现象非常明显。
Abstract:
 On the basis of the daily mean temperature data from the twelve meteorological stations in Khorchin region of Inner Mongolia form 1961 to 2016,the climatic characteristics of the cold and warm days and their transition periods in this area in the past 55 years were analyzed.The results showed that the climate warming trend in Khorchin sandy land was obvious,and the abrupt temperature change occurred in 1988.In the context of global climate warming,the severe cold and cold days in the study area showed not only without obvious downward trend but also a slight upward trend after the abrupt temperature change,the increasing number of high temperature days was obviously higher than the decreasing number of low temperature days.There was little change in the transition periods of slight warm and slight cold,warm and cold,hot and severe cold days in the 55-year scale,but there was the opposite changing trend before and after abrupt temperature change.After the occurrence of abrupt temperature change,the transition period became shorter,the days of maximum warm and cold increased,the cold and warm sharp turnaround was also particularly obvious.
