近日，我国中东部地区遭遇了一轮大范围雨雪冰冻天气，影响范围甚至跨过长江流域，波及南方多个省份。此次天气过程具有强度大、持续时间长、影响范围广等特点，导致多地出现道路结冰、交通受阻、电力设施受损等次生灾害。气象部门指出，这是由于强冷空气与暖湿气流在长江中下游地区持续交汇所致，形成了大范围的冻雨和降雪。冻雨尤其危险，其落地即结冰，对交通、电力和农业造成严重影响。专家提醒公众注意防寒保暖，减少不必要的出行，同时相关部门应加强应急响应，保障民生和基础设施安全。此次极端天气也再次凸显了在全球气候变化背景下，极端天气事件频发、强度增强的趋势，亟需加强气候适应能力建设。
Recently, a large-scale rain, snow, and freezing weather event has affected central and eastern China, extending even south of the Yangtze River and impacting multiple provinces in southern China. This weather system is characterized by its intensity, prolonged duration, and extensive coverage, leading to secondary hazards such as icy roads, transportation disruptions, and damage to power infrastructure. Meteorological authorities attribute this phenomenon to the persistent clash between a strong cold air mass and warm, moist air over the middle and lower reaches of the Yangtze River, resulting in widespread freezing rain and snowfall. Freezing rain is particularly hazardous—it freezes instantly upon contact with surfaces, severely disrupting transport, power grids, and agriculture. Experts urge the public to stay warm, limit non-essential travel, and call on relevant agencies to enhance emergency response efforts to protect public safety and critical infrastructure. This extreme weather event further underscores the growing frequency and intensity of such phenomena under global climate change, highlighting the urgent need to strengthen climate resilience and adaptation capabilities.
