近日，安徽多地在‘三九’寒冬期间气温异常偏高，部分地区日最高气温突破20℃，体感温暖如阳春三月，引发公众广泛关注。‘三九’通常是一年中最冷的时段，出现在冬至后的第19天至第27天之间，按传统节气推算，此时应是冰封雪飘、寒风刺骨。然而，受强盛的暖湿气流和晴朗少云天气共同影响，安徽多地出现反常回暖现象。气象专家指出，此次暖冬现象与全球气候变暖背景下的极端天气事件频发密切相关。一方面，副热带高压位置偏北且强度偏强，为南方地区输送了大量暖空气；另一方面，冷空气活动偏弱，未能有效南下压制升温趋势。这种‘暖如三月’的天气虽让人感到舒适，但也可能对农业、生态及人体健康带来一定影响，例如扰乱作物生长周期、增加病虫害风险等。值得注意的是，短期气温波动并不等同于气候趋势的改变，公众仍需关注后续天气变化，合理安排生活与出行。气象部门将持续监测天气系统演变，及时发布预警信息，保障社会生产生活秩序。
Recently, many areas in Anhui Province have experienced unusually warm weather during the ‘Sanjiu’ period—the coldest stretch of winter—drawing widespread public attention. In some regions, daytime highs have surpassed 20°C, creating a spring-like warmth typically associated with March. Traditionally, ‘Sanjiu’ occurs between the 19th and 27th days after the Winter Solstice and is expected to bring freezing temperatures and biting winds. However, strong warm, moist airflows combined with clear, cloudless skies have led to this anomalous warming.Meteorological experts attribute this unseasonable warmth to the increasing frequency of extreme weather events under global climate change. A stronger-than-usual subtropical high-pressure system has transported warm air northward into southern China, while cold air masses have remained weak and failed to push south effectively. Although the pleasant temperatures offer temporary comfort, they may disrupt agricultural cycles, elevate pest and disease risks, and impact ecosystems and human health.It’s important to note that short-term temperature anomalies do not necessarily reflect long-term climate trends. The public is advised to stay informed about upcoming weather forecasts and adjust daily activities accordingly. Meteorological authorities will continue monitoring atmospheric patterns and issue timely alerts to support public safety and socio-economic stability.
