摘　　要：利用内蒙古锡林浩特国家基准气候站1954—2020年的逐日最低气温数据,分析了锡林浩特地区寒潮过程频数的年代际、年、季节变化特征。结果表明:1954—2020年锡林浩特地区共出现寒潮天气过程603次,平均9次/年;寒潮年均出现次数最多的是20世纪70年代,年均发生次数是10.5次,年均出现次数最少的是20世纪80年代,年均发生次数是7.2次;春季是寒潮过程出现次数最多的季节,共出现210次,平均3.1次/年,秋季是寒潮过程出现次数最少的季节,共出现195次,平均2.9次/年,春、秋、冬三季寒潮过程均呈下降趋势。寒潮天气过程带来的大风、降温、雨雪、沙尘等会引发多种气象灾害,对农牧业、交通运输、电力设施以及人们的健康生活都有比较大的影响。Based on the daily minimum temperature data of Xilinhot national benchmark climate station from 1954 to 2020,the interdecadal,annual and seasonal variation characteristics of cold wave process frequency in Xilinhot area are analyzed.The results show that there were 603 cold wave weather processes in Xilinhot from 1954 to 2020,with an average of 9 times/year;The annual average number of cold waves is the highest in the 1970 s,with an annual average of 10.5 times,and the lowest in the 1980 s,with an annual average of 7.2 times;Spring is the season with the highest number of cold wave processes,210 times in total,with an average of 3.1 times/year.Autumn is the season with the lowest number of cold wave processes,195 times in total,with an average of 2.9 times/year.The cold wave processes in spring,autumn and winter show a downward trend.The strong wind,cooling,rain,snow,sand and dust brought by the cold wave weather process will cause a variety of meteorological disasters,which will have a great impact on agriculture and animal husbandry,transportation,power facilities and people’s healthy life.
