Recently, Yantai in Shandong Province experienced an exceptionally heavy snowstorm, with snow depths exceeding 50 centimeters in some areas. A striking phenomenon—resembling ‘smoke’ rising from the ground—was widely reported. This visual effect is not actual smoke but a natural occurrence known as ‘sea smoke’ or ‘steam fog.’ It happens when extremely cold air moves over relatively warmer bodies of water, such as the sea or unfrozen lakes. The warm water evaporates rapidly, and the vapor instantly condenses into tiny ice crystals upon contact with the frigid air, creating a mist that appears to rise like smoke. Located at the confluence of the Yellow Sea and Bohai Sea, Yantai often sees this phenomenon during winter cold snaps, as seawater retains more heat than the freezing air above. Meteorologists note that while visually dramatic, such conditions usually accompany dangerously low temperatures and strong winds, increasing risks like icy roads and reduced visibility. The recent blizzard disrupted transportation and led to flight cancellations, prompting local authorities to activate emergency responses. The viral phrase ‘Yantai is smoking under the blizzard’ captures not only a rare natural spectacle but also reflects the growing frequency of extreme weather events in a changing climate.
近日，山东烟台遭遇罕见强降雪，积雪深度一度超过50厘米，部分地区甚至出现‘冒烟’奇观。这种现象并非真正的烟雾，而是极寒天气下‘冰雾’或‘蒸汽雾’（也称‘海烟’）的自然现象。当极冷的空气流经相对温暖的水面（如海水、湖泊或未结冰的河流）时，水汽迅速蒸发并在冷空气中凝结成微小冰晶，形成类似白烟的雾气，从地面缓缓升起，远看如同‘冒烟’。烟台地处黄海与渤海交汇处，冬季海面温度高于气温，因此在暴雪或寒潮来袭时，这种‘海烟’现象尤为明显。气象专家指出，该现象虽壮观，但往往伴随极端低温和强风，需警惕道路结冰、能见度降低等次生灾害。此次暴雪也导致交通受阻、航班取消，当地政府已启动应急响应，保障市民安全。‘烟台暴雪下冒烟了’不仅是一道奇特的自然景观，更是气候变化背景下极端天气频发的一个缩影。
