明天，降温将快速推进到长江以南，东北地区东部、黄淮、江汉以及江南东部将出现10至16℃的降温。 长江中下游一带最高气温将降至不足10℃，而且伴随着雨雪，温暖戛然而止，湿冷感明显。 在本轮寒潮过程中，东北地区东部、江淮以及江南东部将是降温核心区，部分地区降温可达12至16℃， 局地降温20℃以上。 今天，降温主要集中在东北、华北地区，其中内蒙古中东部、河北北部、北京、辽宁西部、吉林西部等 地降温可达12℃至16℃，局地降幅可达18℃上下。像吉林、辽宁，最高气温将由3日的冰点之上回到零 下，吉林多地还将低于-10℃。 而今天南方未受到冷空气的影响，还将继续温暖如春，最高气温普遍超过15℃，江南南部、华南等地将 超过20℃。 寒潮发威！今起三天（2月5日至7日）中东部将自北向南出现降温，多地降温将超12℃，局地降幅甚至 可达20℃以上。长江中下游等地前期的温暖一扫而空，伴随雨雪，湿冷感上线。哪里降温最猛烈？降温 何时到你家？ 在冷空气影响间隙，我国大部地区进入升温通道，3日最高气温0℃向北推进到黑龙江东部、吉林北部一 带，立春当天暖意升级，10℃线位于河北北部、北京一带，浙江、江苏中南部、安徽、江西等不少地方 最高 ...

Core Viewpoint - A significant cold wave is expected to hit China starting January 16, leading to a drastic temperature drop across many regions, reversing the recent warm weather experienced during the "Three Nine" period [1][3][6]. Temperature Changes - The first cold wave will bring temperatures down significantly, with some areas experiencing a drop of over 20°C. For instance, Zhengzhou's temperature is projected to fall from nearly 22°C on January 15 to -5°C by January 20, marking a cumulative drop of 26°C [6][7]. - Major cities like Yinchuan, Jinan, and Hohhot will also see substantial temperature declines, with drops around 20°C [6][7]. Timeline of Cold Wave Impact - The cold air will first affect the northwest and eastern regions, with the core temperature drop occurring from January 19 to 21, impacting most of central and eastern China [3][6]. - Specific dates indicate that on January 17, the cold wave will primarily affect northern Xinjiang and parts of Inner Mongolia, while by January 19, most of the central and eastern regions will experience noticeable cooling [3][6]. Weather Conditions - Alongside the temperature drop, regions will also face rain, snow, and strong winds, particularly in northern areas, which may lead to a wind chill effect. Southern regions will experience damp and cold conditions [7][8]. - The cold wave is expected to bring the lowest temperatures of the winter season, with cities like Beijing forecasted to have maximum temperatures below freezing for several consecutive days [6][7].

Core Viewpoint - The article discusses the impact of a cold wave and snow on southern regions of China, highlighting significant temperature drops and providing guidance on how to cope with the cold weather [1][3]. Group 1: Weather Impact - Southern regions experienced severe temperature drops of 10°C to 14°C, marking the coldest day of the winter so far [1]. - The temperature in Jiangsu province is expected to range from -6°C to -4°C in the northern areas and -2°C to 0°C in the southern areas [1]. - The minimum temperature is projected to drop to around -5°C statewide, with frost expected [3]. Group 2: Cold Weather Guidelines - Dressing in layers is recommended, following an "onion-style" approach: inner layer for moisture-wicking, middle layer for warmth, and outer layer for wind and water resistance [5][6]. - Key body parts that are vulnerable to cold should be protected, including the head, neck, and ankles, with suggestions for wearing hats, scarves, and warm socks [8]. - Dietary recommendations include consuming warming, high-protein foods like beef and chicken, while avoiding cold foods that may upset the stomach [9].

Group 1 - In November, the average temperature in China was 4.2℃, which is 0.9℃ higher than the same period in previous years [1] - There were three cold air processes affecting China in November, which is 1.3 times less than the average for the same period [1] - A nationwide cold wave occurred from November 17 to 19, causing significant temperature drops in Northeast China and most of the central and eastern regions, with the maximum drop exceeding 14℃ in 11 national stations [1] Group 2 - Looking ahead, it is expected that three cold air masses will influence China in the next ten days, but their overall intensity will be weak, with less precipitation and higher overall temperatures [1] - In December, temperatures in the northeastern region's central and northern parts, eastern Inner Mongolia, and northern Xinjiang are expected to be lower than the same period in previous years, while most other areas will have temperatures close to or higher than the historical average [1] - The southern agricultural regions may face risks of frost damage, and preparations for wind and cold resistance in agricultural and livestock facilities are advised [2]
