Recently, Beijing recorded its lowest temperature of the winter so far, with minimum temperatures in many areas dropping below minus 15°C, and some regions approaching minus 20°C. According to data from the Beijing Meteorological Bureau, since early January, frequent incursions of strong cold air masses from the north have led to prolonged periods of severe cold across both urban and suburban districts.Experts attribute this intense and persistent cold wave to an unusually active polar vortex and a strengthened Siberian High. The meteorological authorities have issued public advisories urging residents—especially the elderly, children, and those with chronic illnesses—to stay indoors and take precautions against cold-related health risks such as cardiovascular issues.The extreme cold also poses challenges to urban infrastructure, including transportation, heating, and power supply systems. In response, Beijing has activated its low-temperature emergency response mechanism to ensure the smooth operation of essential services and public safety.Notably, despite this record-breaking cold snap, long-term climate trends continue to reflect global warming, which is increasingly linked to more frequent and intense extreme weather events. Meteorologists urge the public to remain aware of climate change and enhance preparedness for such weather extremes.
近日，北京气温再创今冬新低，多地最低气温跌破零下15摄氏度，部分地区甚至接近零下20摄氏度。据北京市气象局监测数据显示，1月上旬以来，受强冷空气频繁南下影响，北京持续遭遇低温天气过程，城区及郊区普遍出现严寒天气。专家指出，此次寒潮强度大、持续时间长，与北极涡旋异常活跃及西伯利亚高压增强密切相关。气象部门提醒市民注意防寒保暖，尤其是老人、儿童及慢性病患者应尽量减少外出，避免因低温引发心脑血管等健康问题。同时，低温也对城市运行带来挑战，包括交通、供暖和电力供应等方面均需加强保障。北京市已启动低温应急响应机制，确保市政设施正常运转和居民生活安全。值得注意的是，尽管当前气温创下今冬新低，但长期气候趋势仍显示全球变暖背景下极端天气事件频发。气象专家呼吁公众关注气候变化，提高应对极端天气的意识和能力。
