图片来源：央视新闻 每经编辑｜毕陆名 尽管风暴天气导致用电需求激增，但由于高压输电线路的输送能力已达饱和，芝加哥地区的电力价格已跌入负值区间。当地时间周一上午10点10分，埃克斯 龙公司旗下ComEd公用事业服务区的实时电力价格跌至-227.93美元/兆瓦时。而周日的平均价格还在50美元以上。 虽然近日席卷中西部北部的极寒天气推高了供暖所需的电力需求，但当远距离输电线路达到承载上限、无法向其他市场输送更多电力时，过剩的电力供应便 会不断累积。 据央视新闻，记者当地时间1月26日获悉，23日以来席卷美国大部分地区的冬季风暴已经造成至少25人死亡。 据悉，纽约州已经发现8人死于户外，其他风暴致死事件发生在得克萨斯州、阿肯色州、马萨诸塞州和堪萨斯州等地。 美国电力跟踪网站数据显示，截至美东时间26日15时30分，全美仍有近70万用户断电。 一场大规模冬季风暴23日至24日夜间横扫得克萨斯州、堪萨斯州等美国中南部地区，带来大范围降雪、雨夹雪和低温天气。据悉，全美已有22个州宣布进入 紧急状态，超过1.3万架次航班受天气影响取消。 另据新华社24日报道，路透社报道，冬季风暴、冰暴及极端寒潮预警已覆盖超过2亿美国民众。美 ...

Core Points - A severe winter storm sweeping across much of the United States since January 23 has resulted in at least 25 fatalities [1] - The storm has led to widespread power outages, affecting nearly 700,000 users as of January 26 [4] - Over 22 states have declared a state of emergency, with more than 13,000 flights canceled due to weather impacts [4] Group 1: Storm Impact - The winter storm has brought significant snowfall, sleet, and low temperatures, with predictions of snowfall exceeding 305 millimeters in severely affected areas [4] - The storm's intensity and scope are described as the most severe of the winter season, with temperatures in states like North Dakota and Minnesota dropping below -45 degrees Celsius [4] - Officials warn that severe cold and ice could lead to serious transportation and power disruptions in affected regions [4] Group 2: Climate Context - The storm is attributed to the expansion of the polar vortex, which can occasionally move south into the U.S. due to climate change [5] - Some experts argue that while global warming is occurring, extreme cold events will still happen, albeit less frequently [5] - Climate scientists indicate that the increase in extreme cold events in the eastern U.S. is linked to warming in the Arctic, which affects climate system fluctuations [5]

据美国国家气象局预测，在落基山脉、中部大平原、中大西洋及东北部受灾最严重区域，降雪量可能超过305毫米。气象预报说，南部大平原、密 西西比河谷下游、俄亥俄河谷及中大西洋地区都将经历零下低温，预计持续至下周初，可能打破这些地区的低温纪录。有关官员警告称，严寒和 冰层可能导致部分地区出现严重交通及电力中断。 美国"准确天气预报"公司气象学家布兰登·白金汉说，得州达拉斯市可能形成约12.7毫米冰层，情况将迅速变得危险。他提醒居民做好"持续数日断 电"的准备。 △美国堪萨斯州民众排队购买生活物资 "这将是场大风暴，"达拉斯居民玛丽塞拉·雷森迪斯在一家商店采购时说，她需为自己和家人备足周末物资。她计划"待在家里，尽量不出门"。为 应对此次风暴，不少民众囤积物资，得州休斯敦市北部一家超市的瓶装水几乎售罄。 在俄克拉何马州首府俄克拉何马城，23日最低气温达零下13.3摄氏度。当地一家咖啡馆经理摩根·梅奥说，顾客早晨蜂拥而至以躲避室外严寒。 一场大规模冬季风暴23日开始侵袭美国，已在得克萨斯州、俄克拉何马州和堪萨斯州部分地区引发降雪。气象预报显示，美国三分之二地区将经 历低温、强降雪、冻雨和冰暴等极端天气，可能导致大范围断电 ...

Core Viewpoint - The article highlights a statement from U.S. President Trump regarding an unprecedented cold wave expected to impact 40 states in the U.S., questioning the narrative around global warming [1] Group 1 - The cold wave is described as a situation that has never been seen before, affecting a significant portion of the United States [1] - Trump's previous characterization of global warming as a hoax is referenced, indicating a longstanding skepticism towards climate change narratives [1]

Group 1: Global Temperature Trends - The World Meteorological Organization confirmed that 2025 continued the trend of record-high global temperatures, with 2026 likely to remain at elevated levels [1] - The Copernicus Climate Change Service reported that 2025 was the third hottest year on record, with a three-year average global temperature exceeding pre-industrial levels by over 1.5 degrees Celsius for the first time [11] - The long-term global warming level is estimated to be approximately 1.4 degrees Celsius higher than pre-industrial levels [11] Group 2: Extreme Weather Events - The northern hemisphere is experiencing extreme weather, including severe snowstorms in Russia's Kamchatka Peninsula and the northeastern United States, as well as cold waves in Europe and heavy snowfall in Japan [1][5][7] - Australia faced a heatwave in early January 2026, with temperatures exceeding 40 degrees Celsius, leading to wildfires and power supply issues [13][15] - Continuous heavy rainfall in southern Africa has resulted in hundreds of deaths and significant flooding in Mozambique, South Africa, and Zimbabwe [21][22] Group 3: Ocean and Climate Impact - The global ocean's upper 2000 meters of heat content reached a record high for the ninth consecutive year, indicating a clear trend of ocean warming [19] - The warming oceans are affecting marine ecosystems and human societies, contributing to lower dissolved oxygen levels and increasing risks of marine heatwaves and coral bleaching [19] - The melting of the Greenland ice sheet may lead to regional sea level declines around Greenland due to land rebound, presenting new challenges for local infrastructure and food security [24] Group 4: Coral Reefs and Microbial Dynamics - Research indicates that coral reefs influence the composition and activity of surrounding microbial communities, shaping energy and nutrient flows in marine ecosystems [15] Group 5: Climate Research Initiatives - A new project named "Ice Memory" aims to store alpine ice core samples in Antarctica for future research, preserving historical climate data and the impact of human activities on climate [26][28]

Core Viewpoint - The article discusses an unprecedented snowstorm in the Kamchatka Peninsula, Russia, which has led to extreme snowfall conditions, with snow accumulation so high that it has buried entire buildings, creating a surreal visual effect that some initially thought was AI-generated [1][4]. Group 1: Extreme Weather Events - Kamchatka has experienced a snowstorm described as a once-in-50-years event, with snow accumulation so severe that windows of buildings are barely visible, and residents must dig paths through the snow to exit [1][4]. - The phenomenon of snow being higher than buildings is attributed to a combination of strong winds, continuous heavy snowfall, and the region's unique topography, which causes snow to accumulate on the windward sides of structures [4][6]. Group 2: Snowfall Patterns in Russia - Russia is characterized by abundant snowfall, particularly in regions like Kamchatka, Siberia, and the Arctic Circle, where deep snow and long snow seasons are common [6]. - Even cities like Moscow, which are not typically known for heavy snowfall, can experience significant snow accumulation during winter, with past events leading to disruptions such as downed trees and flight cancellations due to deep snow [9][11]. Group 3: Climate Change Implications - The article suggests that extreme snowfall events, like the one in Kamchatka, may become more frequent due to climate change, as polar cold air increasingly interacts with warm, moist air, leading to more severe winter weather [11].

中央气象台专家介绍,此次寒潮的"幕后推手"是来自西伯利亚的强冷气团。该冷空气系统正自北向南逐 步推进,影响范围覆盖我国中东部大部分地区。与以往常见的寒潮不同,本次寒潮天气过程并非"猛冲 式"剧烈南下,而是以扩散蔓延的方式逐步渗透,其所携冷空气势力强、影响范围广、持续时间长、降温幅 度大。 通常,影响我国的冷空气多在西伯利亚至蒙古高原一带积聚并逐步加强,形成强盛的西伯利亚冷高压或蒙 古高原冷高压,向南或东南方向侵袭。 1月20日进入大寒节气,也是二十四节气中的最后一个节气,我国多地气温将在大寒时节迎来全年最冷的时 段。寒潮自北向南逐步影响我国大部地区,中东部遭遇入冬以来最强雨雪冰冻天气,我省大部地区最低气 温将维持在-10℃以下,内蒙古阿尔山地区最低气温达到-44.5℃。 大寒往往处于数九时节的"四九"前后,已是"冰上走"的时节。此时,寒潮影响依然频繁,北方积雪难融,南方 多地进入一年中最冷的时段。从中国气象局提供的1991年至2020年气象数据统计发现,大寒时节全国平 均气温仅有-4.48℃,寒意十足。 中央气象台近期持续发布寒潮、暴雪、冰冻等多个预警,这一冬季复合型灾害的关注度持续攀升。这场 寒潮为什么有这 ...

Core Viewpoint - The article discusses the significant fluctuations in winter temperatures in the Northern Hemisphere, particularly in Northeast China and North America, attributing these changes to the polar vortex [1][3]. Group 1: Polar Vortex - The polar vortex is identified as the source of cold air, influencing both the accumulation and dynamics of cold air [1]. - A strong polar vortex keeps cold air contained, making it difficult for cold air to move southward [1]. - When the polar vortex weakens, it can lead to a southward movement of cold air, resulting in cold waves [3]. Group 2: Global Warming Impact - There is a theory suggesting that global warming reduces the temperature difference between warm and cold regions, leading to a weakened circulation that allows cold air to descend [3]. - This phenomenon implies that during global warming, the frequency of cold events may actually increase, contrary to common expectations [3].

李宁分析，当时气温的大幅偏高，为寒潮预留了巨大的降温空间。这股寒潮经过堆积和酝酿，正逐 渐渗透南下，并伴有大范围雨雪。此轮天气过程将彻底扭转前期偏暖格局，影响会从小寒末期持续至大 寒初期，甚至可能带来入冬以来的最冷时段。 在此背景下，不同区域冷暖体验各异。李宁指出，华北北部至东北一带，小寒期间本就偏冷，大寒 节气将进一步加剧寒冷；而在江南中南部、华南等地，大寒节气气温依然会持续小幅偏高，但也不会再 出现像小寒节气期间那样夸张、超前的温暖。 长期看规律：几十年气象数据印证"小寒胜大寒" 今年的特殊情况，并不能代表长期的气候规律。当我们把目光投向更长的时间尺度，结论则有所不 同。中国气象局气象分析师李倩指出，从气象数据上看，"小寒胜大寒"才是常态。 盘点1991年到2020年这三十年的数据，全国平均气温在小寒节气会达到全年最低点，为零下 5.0℃；大寒节气次之，为零下4.5℃。这明确地印证了"小寒胜大寒，常见不稀罕"的说法。李倩进一步 说明，这一规律具有长期的稳定性："从二十世纪五十年代有系统气象记录以来，一直到二十一世纪 初，绝大多数年代都是小寒更冷。仅上世纪七十年代例外，当时大寒仅以0.02℃的微弱差距略胜一 ...
