近期，中国新疆阿勒泰地区气温骤降，部分地区最低气温跌破-40℃，甚至低于同期北极部分区域的温度，引发广泛关注。这一现象看似反常，实则与特定天气系统密切相关。气象专家指出，此次极端低温主要受强冷空气南下和西伯利亚高压增强影响。阿勒泰地处中国最北端，靠近蒙古和俄罗斯，冬季本就寒冷，加上地形开阔、缺乏屏障，冷空气可长驱直入，导致气温急剧下降。与此同时，北极部分地区因全球变暖及大气环流变化，反而出现阶段性回暖，使得阿勒泰在短时间内‘冷过北极’。需要强调的是，这种比较是局部和暂时的，并不代表整体气候趋势。科学家提醒，极端天气事件频发正是气候变化的体现，公众应提高防寒意识，同时关注长期气候行动。
Recently, temperatures in Altay Prefecture in China’s Xinjiang region plummeted, with some areas dropping below -40°C—colder than parts of the Arctic at the same time—drawing widespread attention. While this may seem unusual, it is closely linked to specific weather patterns. Meteorologists explain that the extreme cold was primarily caused by a strong southward surge of cold air and an intensified Siberian High pressure system. Located in China’s northernmost region near Mongolia and Russia, Altay naturally experiences harsh winters. Its open terrain and lack of natural barriers allow cold air masses to sweep through unimpeded, causing rapid temperature drops. Meanwhile, certain Arctic regions experienced temporary warming due to global climate change and shifts in atmospheric circulation, making Altay temporarily colder than the Arctic. It’s important to note that this comparison is localized and short-term, not reflective of broader climate trends. Scientists caution that such extreme weather events are increasingly symptomatic of climate change, urging public awareness of cold-weather safety and long-term climate action.
