Why It Matters

近期全国大部地区经历了一波气温回升,东北地区气温较常年同期偏暖明显。

中国天气网讯 升温余额不足!近期全国大部地区迎来一波回暖,不过,明天(11月14日)起至18日,冷空气再度发力,南北方多地气温迎断崖式回落,冰冻线将一路南压至淮河流域,冷意回归。同时大范围雨雪上线,东北局地降雪猛烈。中国天气网推出全国降温进程图,一起看各地何时迎冷暖逆转。

本周进入冷空气间歇期,我国大部地区气温稳步回升,最高气温10℃线北抬至黑龙江东南部一带,20℃线北抬至长江中下游一带。其中东北地区较常年同期偏暖最为突出,昨天沈阳最高气温冲上16℃,暖意十足,体感堪比10月中旬。

不过,短暂回暖后,南北方又将迎来大降温。中国天气网气象分析师孙倩倩介绍,14日至18日将有两股冷空气接力南下,两股冷空气实力不算很强,但前期偏暖格局为降温预留了空间,累计降温幅度会比较大。降温过后,南北方气温将大面积创下半年来新低,19日凌晨,最低气温0℃线会南压至淮河流域,位置比上一轮寒潮偏南。

从中国天气网推出的全国降温进程图来看,降温将自北向南逐步铺展。14日,西北、东北、华北北部率先迎来降温,15日,降温范围进一步扩大,覆盖北方大部地区,局地降温可达12℃或以上;本轮降温后,北方大部地区将由偏暖转为偏冷,像沈阳,最高气温将由16℃以上跌至3℃,兰州、济南将从接近20℃降至个位数。

南方降温时间滞后于北方,冷空气抵达前仍会继续升温。16日至17日,随着冷空气主体抵达,南方也将陆续加入降温行列,部分城市降温幅度可超8℃;18日冷空气还将跨过乌蒙山与南岭,降温区域直抵华南、云南一带。城市中,武汉15日最高气温21℃,19日会降至11℃,长沙15日22℃,19日将跌至13℃,前后冷暖反差明显。

随着冷空气南下和暖湿气流北上配合,我国将出现大范围雨雪天气。预计,15日至17日西北地区中东部、华北北部和西部、东北地区、黄淮西部等地将出现降雪或雨转雪。据孙倩倩分析,本轮华北降雪强度整体不及上一轮寒潮,但东北地区东部降雪强度将明显升级,部分地区有暴雪、大暴雪,局地可达特大暴雪。目前时效仍较远,需保持关注。

中国天气网提醒,11月中旬冷空气活动趋于频繁,我国大部地区的气温起伏较大,公众请根据气温变化适时调整着装,谨防感冒。下周东北地区降雪强度大,容易出现道路积雪、结冰和能见度降低现象,对交通出行可能造成不利影响,请公众提前做好防范措施。
