摘要
分析了连云港市小麦越冬期间(12月中旬～翌年2月中旬)2次区域性寒潮天气过程。结果表明,2次寒潮过程都属于横槽转竖型,2次寒潮冷空气的强度和爆发速度不同,导致其降温程度也不同;2次寒潮发生前都出现了地面升温现象;欧洲中心数值预报对寒潮初始时间的预报具有很好的指导意义。
2 territorial cold wave weather processes in wintering period of wheat （from the second ten clays of December to the second ten days of February） in Lianyungang City were analyzed. The results showed that 2 cold wave processes were all the types of transversal trough to vertical trough, the strength and outbreak speed of the cold air of 2 cold waves were different, which lead to different cooling degree. Surface heating phenomenon appeared before occurrence of 2 cold waves. European Center numerical forecast had good guiding significance for initial forecast of cold waves.
