According to the latest forecast from the National Meteorological Center, multiple cold air masses will successively affect central and eastern China next week, causing a significant drop in temperatures. Strong cold surges are expected in early and mid-December, with temperature declines of 8°C to 12°C in some areas—and locally exceeding 14°C—accompanied by strong winds and wintry precipitation, leading to a notably lower wind chill.Does this mean a cold wave is imminent? Under China’s meteorological criteria, a cold wave is defined as a cold air event that causes a temperature drop of at least 8°C within 24 hours or 10°C within 48 hours, along with a daily minimum temperature falling to 4°C or below. Current forecasts suggest that parts of North China, Northeast China, and the Huang-Huai region may meet these thresholds. Areas such as eastern Inner Mongolia, Heilongjiang, and Jilin should be especially vigilant against the adverse impacts of sharp temperature drops.Meteorologists advise the public to closely monitor short-term weather updates, dress warmly, and take precautions against the cold. Additionally, sectors including agriculture, transportation, and energy should prepare in advance to mitigate potential disruptions from freezing rain, snow, and low temperatures. While this upcoming cold spell is notably strong, whether it will be officially classified as a ‘cold wave’ depends on actual observational data from local monitoring stations.
据中央气象台最新预报，下周将有多股冷空气接连影响我国中东部地区，气温将明显下降。其中，12月上旬前期和中期各有一次较强冷空气过程，部分地区降温幅度可达8℃至12℃，局地甚至超过14℃。伴随大风和雨雪天气，体感温度将显著降低。那么，这是否意味着将迎来寒潮？根据我国气象标准，寒潮是指使某地日最低气温在24小时内降温幅度≥8℃，或48小时内降温≥10℃，且最低气温降至4℃或以下的强冷空气活动。从目前预报来看，华北、东北及黄淮等地的部分区域可能达到寒潮标准，尤其是内蒙古东部、黑龙江、吉林等地，需警惕剧烈降温带来的不利影响。气象专家提醒，公众应密切关注临近天气预报，及时增添衣物，注意防寒保暖；同时，农业、交通、能源等部门也需提前做好应对准备，防范低温雨雪冰冻对生产生活造成的潜在风险。虽然此次冷空气过程强度较强，但是否被正式定义为‘寒潮’，还需依据各地实际监测数据最终判定。
