The first cold wave of the year brought intense snow, freezing rain, and icy conditions, affecting a vast area with exceptional strength. According to data from the National Meteorological Center, in early January, more than 20 provinces experienced sharp temperature drops, with many regions seeing declines exceeding 10°C—some plunging below -20°C. Central and eastern China faced widespread snowfall and freezing rain, with cumulative snowfall ranging from 10 to 30 millimeters and locally surpassing 40 millimeters. Freezing rain impacted provinces including Hubei, Hunan, and Guizhou, with ice accumulation reaching over 5 millimeters in some areas, significantly disrupting transportation, power grids, and agriculture. For instance, high-speed rail lines such as Beijing–Guangzhou and Shanghai–Kunming were either slowed or suspended due to ice on overhead wires, and over 1,000 kilometers of highways were closed. Meteorologists attribute this extreme event to the collision of Arctic-origin cold air with warm, moist air masses, noting it is the strongest cold wave of its kind in the past five years for this season. The public is advised to stay alert to weather warnings and take precautions against cold, slips, and emergencies.
今年首场寒潮雨雪冰冻天气来势迅猛，影响范围广、强度大。据中央气象台数据显示，1月上旬，全国超20个省份遭遇强降温，多地气温骤降10℃以上，部分地区最低气温跌破-20℃。同时，中东部地区出现大范围雨雪冰冻天气，累计降雪量达10至30毫米，局地超过40毫米；冻雨覆盖湖北、湖南、贵州等省份，最大冻雨厚度达5毫米以上，对交通、电力和农业造成显著影响。例如，京广、沪昆等多条高铁线路因接触网覆冰限速或停运，高速公路封闭超千公里。气象专家指出，此次寒潮是受极地冷空气南下与暖湿气流交汇所致，其综合强度为近五年同期最强。公众需持续关注预警信息，做好防寒防滑及应急准备。
