Recently, Beijing has been hit by a prolonged cold wave, with meteorological data showing that the city has remained in a so-called ‘deep freeze mode’—defined as daily minimum temperatures below -10°C—for over 170 consecutive hours. This extreme cold spell began in late December 2024, driven by repeated surges of intense cold air from the north, pushing temperatures in some areas below -15°C. Although ‘deep freeze mode’ is not an official meteorological term, it has become a popular way for the public to describe extended periods of severe cold without significant warming.Experts attribute this unusually strong and persistent cold snap to an abnormally active polar vortex and an intensified Siberian High. The prolonged low temperatures have significantly impacted daily life—spiking heating demand, disrupting transportation—and posed challenges to agriculture, energy supply, and urban infrastructure. In response, Beijing has activated emergency protocols, enhancing heating services, road de-icing operations, and support for vulnerable populations.While the frigid conditions are expected to persist for several more days, meteorologists forecast a gradual temperature rebound toward the end of the month as the cold air weakens. Residents are advised to continue taking precautions against the cold and stay updated on weather alerts to safely navigate this harsh winter period.
近日，北京遭遇持续寒潮天气，气象部门数据显示，全市已连续超过170小时处于日最低气温低于-10℃的‘冰冻模式’。这一现象自2024年12月下旬开始，受强冷空气频繁南下影响，北京多地气温屡创新低，部分区域甚至跌破-15℃。‘冰冻模式’并非官方气象术语，而是公众对长时间低温严寒天气的形象描述，通常指日最低气温持续低于-10℃且无明显回暖迹象的状态。气象专家指出，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。长时间低温不仅对居民生活造成影响，如供暖需求激增、交通出行受阻，也对农业、能源供应和城市基础设施带来挑战。北京市已启动应急响应机制，加强供热保障、道路除冰和弱势群体防寒救助工作。尽管寒冷天气将持续一段时间，但气象部门预计，随着冷空气势力减弱，本月底前后气温将逐步回升。市民需继续做好防寒保暖措施，关注最新天气预警信息，确保安全度过严寒期。
