气象分析师介绍，从水汽和动力条件看，12日20时前后，太原和郑州的降雪可能就会停止。20时之后， 石家庄的降雪也将逐渐减弱、趋于结束。而北京则会下到13日凌晨5时前后，天津比北京略晚，济南的 降雪将最晚结束，估计要到13日11时前后。 所以，这个周末的出行原则是：能宅则宅，如需出门，务必"慢"字当头。道路千万条，安全第一条。 周末气温集中创新低 南北集体"冻透" 如果说雨雪是本轮寒潮的"前菜"，那么本周末气温集中创新低才是它的压轴"大戏"。 12月12日，北京、天津、济南等多个城市终于等来了今冬的第一场雪！不要觉得下了雪，寒潮的影响就 要结束了。本周末，气温将再创新低，一句话总结：雪花是浪漫的，但接踵而至的寒冷是"硬核"的。 冬天氛围感拉满 多地现今冬初雪 12日白天，寒潮的"冰雪军团"正在大举推进。8时至14时，陕西大部、山西、河北、北京、天津、河南 大部、山东西部出现了成片的降雪，冬天的氛围感拉满。大城市中，太原、郑州、北京、石家庄、天 津、济南都在12日签收到了今冬初雪。 本周末将是气温集中创新低的时段。加上北风助阵，风寒效应显著，体感温度会比实际气温更低，"冷 到骨头里"的感觉要来了。 大城市中，预计 ...

这股弱冷空气实力其实并不强，除了短暂存在的阴霾，带来的降温也有限，这两天的最高气温仍有 17℃左右，不会太冷。 周三起气温强力反弹，开启"锋前增温"模式。据浙江天气网消息，周三周四，全省会由北往南出现 最高气温顶点，周三浙北率先来到升温顶点，达20℃左右，周四浙中南直冲22℃，届时正午时光很暖， 但早晚还是冷的。这两天杭州白天最高气温也可升至22℃-23℃，甚至超过冷空气来临前的水平。 新的一周拉开序幕，弱冷空气悄然抵达。周一（12月8日），杭州主城区最高温15.8℃，较上周末 的"2字头"有些回落，倒也不冷，就是少了些明媚阳光，多了些灰蒙阴霾，视野所至像是蒙了层"磨砂玻 璃"，给原本色彩明丽的西湖、钱塘江等水面也加上了层"怀旧滤镜"。 据杭州市气象台消息，北方冷空气南下，上游污染物随之向南输送，周一早晨开始，杭州大气中的 PM2.5含量显著上升，空气质量明显下降，上午9-10时，AQI已达到中度污染级别。好在，夜里以后， 随着污染物进一步向南扩散，杭州空气质量逐渐好转。 当然，熟知天气"套路"的朋友都知道，强势回暖之后往往跟随着气温"大跳水"。周五夜里至周六 （12-13日），受一股冷空气影响，全省会迎来一 ...

风力越大，人体的热量流失越快。数据显示，气温高于0℃时，风力每增加2级，体感温度下降3℃至5℃；气温低于0℃时，风力每增加2级，体感温度降幅可 达6℃至8℃。所以同样的温度下，刮风时总感觉更冷。 风寒效应会显著增加健康风险，容易引发冻伤、感冒，心脑血管疾病患者尤其需要注意防护。"风寒效应"主要发生在裸露的皮肤上，尤其是头部位置。当气 温降至4℃左右，约一半人体热量从头部散发；气温达零下10℃时，这一比例升至四分之三。所以外出时，应穿戴防风保暖的衣物，减少皮肤暴露，特别要 加强头部保暖，这是抵御风寒的关键。 央视网消息：近期寒潮频发，尤其是在大风、降雪的天气里，户外常感"寒风刺骨"。这不仅是心理感受，更是有科学依据的，这其实是"风寒效应"。我们该 如何做好防护呢？ "风寒效应"是指风导致体感温度低于实际气温的现象。无风时，人体周围会形成一层相对稳定的暖空气，起到保温作用。一旦刮风，这层暖空气便被吹散， 加速身体热量流失，使人感觉更冷。 此外，湿润的空气导热性更强，所以当空气湿度越大时，"风寒效应"越明显。建议出门时不仅关注气温和风力，还要综合考虑湿度，做好全方位的保暖措 施。 ...

周五（28日）、周六（29日）白天以晴到多云天气为主，气温也略有回升，预计白天最高气温在7~10℃ 之间，午间时段适宜安排户外活动。 周六夜间冷空气南下，北风再起，阵风五级左右；周日（30日）北风萧瑟，风寒效应明显。 北京市气象台提醒，今天傍晚至夜间北风较大，出行请注意防风防寒，谨防高空坠物。风干物燥，请注 意用火用电用气安全，防范火灾发生。早晚寒冷，谨防心脑血管和呼吸道疾病。 新京报讯（记者王景曦）今天（11月26日）白天京城天空云量有所增多，阳光微弱，预计午后最高气温 在9℃上下，午间时段总体比较适宜户外活动和开窗通风。下午到前半夜山区还会有雨夹雪或雪。 据北京市气象台预计，今天傍晚前后，北风从西部山区开始影响京城，预计今天傍晚至夜间有三四级偏 北风，阵风七级左右，西部山区局地阵风可达九级以上，山区局地还会伴有扬沙。 明天（27日）白天风力有所减小，但仍有五级左右的偏北阵风，同时，气温也有所下降，白天最高气温 在7℃左右。 ...

Summary of Key Points Core Viewpoint - The article discusses the upcoming cold wave affecting most parts of China from November 14 to 17, leading to significant temperature drops and potential weather hazards. Group 1: Temperature Changes - The average temperature in most regions of China has been 1 to 3 degrees Celsius higher than the same period in previous years, with some areas exceeding 4 degrees Celsius [1] - The cold wave is expected to cause a temperature drop of 6 to 10 degrees Celsius in northern and central eastern regions, with some areas experiencing drops of 12 to 14 degrees Celsius [2] Group 2: Weather Forecast - The cold wave will first impact northern regions such as northern Xinjiang, Gansu, Ningxia, and central western Inner Mongolia from November 14 to 15, before moving to central eastern areas from November 16 to 17 [2] - Rain and snow are forecasted, with small to moderate snow or sleet expected in northern Xinjiang and eastern Tibet on November 14, and in parts of Inner Mongolia and northeastern Heilongjiang on November 15 to 16 [3] Group 3: Public Advisory - The public is advised to pay attention to local meteorological updates and adjust clothing accordingly due to the expected strong winds and potential rain and snow, which may lead to slippery roads and low visibility [6] - It is recommended to choose appropriate clothing to minimize skin exposure, especially in colder temperatures, as significant heat loss occurs through exposed body parts [22][28]

Core Points - The article discusses the differences in winter experiences between northern and southern China, emphasizing the impact of humidity on perceived temperature [3][7][10] - It highlights the increasing average humidity levels in southern regions over the years, which contributes to a colder feeling despite higher actual temperatures [4][5][12] Humidity and Temperature Perception - The average relative humidity in eastern, southern, and southwestern China exceeds 70% during winter, while northern regions remain below 65% [4][5] - The "wet cold effect" in southern China leads to a significant difference in perceived temperature, with a potential 5°C difference under similar conditions [7][10] Clothing Recommendations for Southern Winter - The article suggests avoiding cotton clothing, particularly "夹棉睡衣" (cotton-padded sleepwear), due to its high moisture absorption, which exacerbates the cold feeling [10][12][15] - Recommended materials include synthetic fibers like polyester, which have low moisture absorption and better insulation properties [15][17] - A layered clothing approach is advised, with waterproof outer layers and insulating middle layers to retain warmth [17][23] Bedding and Sleeping Comfort - Suggestions for bedding include using synthetic materials that remain dry and warm, as well as regularly airing out bedding to reduce moisture [23][25] - The article emphasizes the discomfort of transitioning from warm clothing to cold bedding, highlighting the need for appropriate materials to enhance sleep quality during winter [23][25]

Core Viewpoint - The article discusses the popularity and practicality of wearing outdoor jackets, specifically "冲锋衣" (softshell jackets), in northern China during winter, questioning their necessity and effectiveness in urban settings [1][3][12]. Group 1: Definition and Standards - The national standard defines "冲锋衣" as outdoor clothing made from waterproof and breathable fabric, designed for outdoor activities [5]. - Key features distinguishing "冲锋衣" from regular jackets include waterproof breathability, colorfastness, and durability [8][9][10].

Group 3: Practicality in Northern China - The article argues that the waterproof feature is less relevant in northern winters, where conditions are typically dry and cold, questioning the need for such jackets [12][17]. - The focus for winter clothing in northern regions should be on wind resistance rather than waterproofing, as wind chill significantly affects perceived temperature [17][21]. Group 4: Recommendations for Winter Clothing - Practical suggestions for northern workers include choosing jackets that effectively block wind, with features like hoods and elastic cuffs, rather than prioritizing waterproof capabilities [17][21]. - The article also highlights common issues with winter clothing, such as noise and static electricity, suggesting solutions like using fabric softeners and maintaining humidity [22][24].
