This winter’s climate has shown significant regional differences. In northern areas such as Northeast and North China, temperatures have been generally lower than average, with frequent snowfall and even extreme cold waves in some regions, disrupting transportation and daily life. In contrast, southern regions—particularly South and Southwest China—have experienced relatively mild and dry conditions, with above-average temperatures and less precipitation, making for an unusually warm winter that defies traditional expectations of a harsh ‘cold season.’ This uneven pattern of cold north and warm south is closely linked to anomalies in atmospheric circulation driven by global climate change. For instance, an unstable polar vortex has led to frequent outbreaks of cold air moving southward, while a persistently strong subtropical high has suppressed cold air activity in the south. Overall, this winter reflects both the increasing frequency of extreme weather events and the growing complexity of the climate system. Meteorologists advise the public to prepare for more unpredictable winter weather patterns in the future and to take appropriate measures for cold protection and extreme weather response.
今年冬天的气候呈现出明显的区域性差异。在北方地区,如东北和华北,气温普遍偏低,降雪频繁,部分地区甚至出现了极端寒潮,给交通和日常生活带来一定影响。而在南方,尤其是华南和西南地区,气温则相对偏高,降水偏少,部分城市经历了较为干燥温暖的冬季,与人们传统印象中的‘寒冬’大相径庭。这种冷暖不均的现象,与全球气候变化背景下大气环流异常密切相关。例如,北极涡旋的不稳定导致冷空气南下频繁,而副热带高压的持续偏强则抑制了南方的冷空气活动。总体来看,今年冬天既体现了极端天气事件增多的趋势,也反映出气候系统日益复杂的变化特征。气象专家提醒公众,未来冬季可能出现更多不可预测的天气模式,需加强防寒保暖和应对极端天气的准备。
