【#本轮寒潮为何这么冷#】#四九开启速冻模式#据央视新闻，昨天是"四九"的第一天，从昨天起，今年 以来降温最强、雨雪强度最强的一轮寒潮天气过程已经开始。这轮寒潮有哪些特点？将一直持续到什么 时候？中国气象局气象分析师胡啸分析，这轮寒潮天气的特点很鲜明，首先就是体感变化巨大。刚刚过 去的"三九"，全国平均气温偏高，偏暖的程度是同期历史的第三暖，其中河南是历史最暖的"三 九"。"三九"异常暖，"四九"寒冬至。寒潮到来，降温空间很大。从今天（18 日）开始到21日，中东部 都会有明显降温，气温会普降6~12℃，不少地区降温幅度甚至会突破15℃，大家体感好似速冻。第二个 特点是降雪强。寒潮移动相对比较慢，在渗透南下的过程当中有水汽配合。昨天（17 日）华北地区陆 续降雪，今天（18 日）河南山东降雪增强，19日降雪范围最广也会最强。陕西南部、山西南部、河 南、湖北北部、安徽、江苏的北部等地会有大雪甚至暴雪天气。第三个特点是冻雨范围广。这是今冬首 轮大范围的冻雨天气。寒潮渗透南下，在近地面形成冷垫。大气的中层暖湿气流发展，所以整层大气特 别容易形成上冷中间暖近地面也冷的格局，有利于冻雨的形成。19日到21日，在湖北的西 ...
