摘　　要：利用1957—2019年随州国家基本气象站资料,采用线性趋势、气候倾向率、寒潮综合指数等统计方法,分析了随州寒潮频次、强度变化特征。结果表明:10月—翌年4月为寒潮活动期,近63年寒潮频次整体呈增加趋势;2011—2019年发生次数最多,平均1年3遇;11月和3月为发生寒潮次数最多月和次多月,1月寒潮最强;值得注意的是,2011—2019年虽然强寒潮较少,但中等和弱寒潮呈明显增多趋势。Based on the data of Suizhou National Basic Weather Station from 1957 to 2019,Statistical methods such as linear trend,climate tendency rate and cold wave comprehensive index are used,The frequency of Suizhou cold wave is analyzed.Characteristics of intensity variation.The results show that:October to April of the following year is the cold wave activity period,In recent 63 years,the frequency of cold wave showed an overall increasing trend,It occurred the most frequently from 2011 to 2019.Average 3 times a year;November and March are that month with the most frequent occurrence of cold wave,The cold wave is strongest in January.It is worth noting that although there are few strong cold waves from 2011 to 2019,However,the moderate and weak cold waves showed an obvious increasing trend.
