| 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。

| Abstract: | 2 territorial cold wave weather processes in wintering period of wheat(from the second ten days 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 go... |
