近日，受强冷空气与暖湿气流共同影响，我国东北地区迎来新一轮强降雪天气过程。中央气象台发布暴雪黄色预警，指出黑龙江中东部、吉林东部等地部分地区将出现大到暴雪，局地积雪深度可达15厘米以上。此次降雪具有强度大、持续时间长、影响范围广等特点，可能对交通、农业及居民生活造成一定影响。气象专家分析，本次强降雪主要源于西伯利亚冷空气南下，与来自日本海的暖湿水汽在东北地区交汇，形成强烈辐合上升运动，从而导致大量降雪。此外，地形抬升作用也进一步增强了降雪强度，尤其在长白山和小兴安岭等山区，可能出现极端积雪。相关部门已启动应急响应机制，加强道路除雪、电力保障和民生服务。公众需注意防寒保暖，减少不必要的外出，防范因积雪和道路结冰引发的安全事故。同时，设施农业需做好棚舍加固和保温措施，避免因暴雪造成损失。预计本轮降雪将在未来48小时内逐渐减弱，但低温天气将持续，提醒民众持续关注最新天气预报和预警信息。
Recently, a new round of heavy snowfall has hit northeastern China due to the combined influence of a strong cold air mass and moist warm airflow. The Central Meteorological Observatory has issued a yellow alert for blizzard conditions, forecasting heavy to severe snowfall in parts of central and eastern Heilongjiang and eastern Jilin, with localized snow depths exceeding 15 centimeters. This snow event is characterized by its high intensity, prolonged duration, and wide impact area, potentially disrupting transportation, agriculture, and daily life.Meteorologists explain that the intense snowfall results from Siberian cold air moving southward and colliding with moisture-laden air from the Sea of Japan over northeastern China, creating strong upward motion and heavy precipitation. Additionally, orographic lift—enhanced by mountainous terrain such as the Changbai and Xiaoxing’an Mountains—further intensifies snowfall, possibly leading to extreme snow accumulation in these regions.Local authorities have activated emergency response protocols, ramping up snow removal on roads, ensuring power supply stability, and enhancing public services. Residents are advised to stay warm, limit non-essential travel, and remain vigilant about hazards from snow accumulation and icy roads. Farmers operating greenhouse facilities should reinforce and insulate their structures to mitigate potential damage.The snowfall is expected to gradually subside within the next 48 hours, though freezing temperatures will persist. The public is urged to closely monitor updated weather forecasts and official warnings.
