| 摘 要： | 利用广东省１１个代表站１９５１－１９９４年每日气温（包括日平均和日最低气温）资料，分析了广东省近４４年来寒潮活动的气候特征。首先，根据广东省气象局规定的寒潮标准，寻找出每个站所有的寒潮过程，在引基础上分析了广东寒潮的地区分布特征。其次，只要１１个代表站中１站或１站以上出现寒潮就认为是一次寒潮过程。在此条件下的统计表明，广东省在４４年中一共出现了１０３次寒潮过程，影响时间从１０月底至３月中旬，其中以

| Abstract: | The climate characteristics of cold wave action are studied using the data of 11 stations'daily temperatures(daily mean and the lowest) in Guangdong Province during 1951-1994.Firstly,according to cold wave standard of Guangdong Province,all of the processes in every station are found,and the distribution characteristics are analyzed;Secondly, it is shown that there are 103 times cold wave processes in recent 44 years.The influence range is from 1 station to 11 stations.77.6% of them occur in Dec.,Jan. and Feb.,and the processes have interannual and interdecade variabilities;Finally,a strength index of cold wave is assessed,and the intermonth and interdecade variabilities are studied. |
