Recently, many regions in China have experienced dramatic temperature swings—from ‘super warm’ to ‘extremely cold’—sparking widespread public concern about climate change and meteorological anomalies. The term ‘super warm’ refers to unusually high temperatures during what should be the coldest part of winter, with some areas even setting record highs for this time of year. This warmth was quickly followed by a powerful cold snap, causing temperatures in certain regions to plummet by more than 10°C within days, resulting in an ‘extremely cold’ situation. Such rapid shifts between extremes not only disrupt daily life and pose health risks but also challenge agriculture, transportation, and energy systems. Meteorologists explain that these extreme weather events are closely linked to disruptions in atmospheric circulation driven by global warming. Arctic warming destabilizes the polar vortex, allowing cold air to surge southward more easily, while warm, moist air masses frequently move northward. Their collision intensifies weather instability. As extreme weather becomes more frequent, enhancing early warning systems, strengthening infrastructure resilience, and raising public awareness of disaster preparedness are crucial steps in adapting to a changing climate.
近期，我国多地经历了从‘超级暖’到‘非常冷’的剧烈气温波动。这种极端天气现象引发了公众对气候变化和气象异常的广泛关注。所谓‘超级暖’，指的是在冬季本应寒冷的时段，气温却异常偏高，部分地区甚至创下同期历史最高温纪录；而随后寒潮迅速南下，带来断崖式降温，部分地区气温骤降10℃以上，形成‘非常冷’的局面。这种短时间内剧烈的冷暖交替，不仅影响人们的日常生活和健康，也对农业、交通、能源供应等带来挑战。气象专家指出，此类极端天气与全球气候变暖背景下的大气环流异常密切相关。北极变暖导致极地涡旋不稳定，冷空气更容易南下，而暖湿气流又频繁北上，两者交汇加剧了天气的不稳定性。面对愈发频繁的极端天气事件，提升气象预警能力、加强基础设施韧性、提高公众防灾意识，已成为应对气候变化的重要举措。
