近日，北京遭遇罕见寒潮，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0℃的‘冰冻模式’。这一持续低温过程自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，部分地区夜间最低温甚至跌破-15℃。气象专家指出，此次‘超长待机’的冰冻天气为近十年来少见，主要原因是北极冷涡异常活跃，配合西伯利亚高压稳定维持，导致冷空气持续堆积并南侵。长时间低温不仅对市民日常生活造成影响，如水管冻裂、交通受阻、供暖需求激增等，也对农业、能源供应和城市运行带来挑战。相关部门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。气象部门预计，未来几天冷空气势力将略有减弱，但气温回升缓慢，公众仍需注意防寒保暖，防范低温相关健康风险。
Recently, Beijing has been hit by an unusual cold wave, with meteorological data showing that the city has remained in a ‘deep freeze’ mode—defined as daily minimum temperatures below 0°C—for over 170 consecutive hours. This prolonged cold spell began in late December, driven by repeated surges of strong cold air from the north. In some areas, nighttime lows have dropped below -15°C. Experts note that this extended freezing period is among the most severe in the past decade, primarily due to an unusually active polar vortex and a persistently strong Siberian High, which together have funneled continuous cold air southward into northern China. The sustained low temperatures have disrupted daily life—causing frozen pipes, transportation delays, and soaring heating demand—and posed challenges to agriculture, energy supply, and urban infrastructure. Authorities have activated emergency response protocols, enhancing heating services, road de-icing operations, and support for vulnerable populations. While forecasts suggest a slight weakening of the cold air mass in the coming days, temperatures are expected to rise only gradually, and residents are advised to stay warm and guard against health risks associated with extreme cold.
