吉林雾凇形成的起因

吉林市松花江畔的雾凇奇景，是由于“严寒的大气和温暖的江水”这对相互矛盾的自然条件所形成的。冬季，吉林市气候严寒，清晨气温常常降至零下20—25℃，然而松花湖水闸底部丰满水电站水闸放出来的湖水却保持在零上4℃。这种25—30℃的温差导致湖水刚一出闸口时就会形成浓雾。
雾凇是一种附着在地面物体（如树枝、电线）迎风面上白色或乳白色不透明的固态水颗粒。它也是由过冷水滴凝结而成。然而，这些过冷水滴并非从天而降，而是由风携带进气流中的。这种小水滴实际上就是云中存在的云滴，在与地表接触后迅速凝结成固态。由于雾凇中存在大量空隙，因此呈现出完全不透明的白色。雾凇轻盈洁白，附着在树木物体上，宛如琼树银花，清秀雅致。
吉林市松花江畔的雾凇奇景，因其独特性和美丽而闻名东亚。由于温差和自然条件的特殊性，这种自然现象在其他地方是少见的。正因如此，吉林市松花江畔的雾凇成为了当地驰誉东亚的旅游胜地。
[翻译] The iced up phenomenon on the surface of the river in Jilin City is a natural wonder that attracts many tourists every year. The reason for this phenomenon is that there are "cold and cold atmospheric conditions and warm river water" in Jilin City. In winter, the temperature of the morning in Jilin City usually drops below -20 to -25 degrees Celsius, but the water in Xinghu Lake, which is located at the bottom of the丰满水电站, still maintains a temperature of around 4 degrees Celsius. This 25-30 degree Celsius temperature difference causes a rapid rise in mist when the water from the Xinghu Lake outlet is exposed to such cold air.
Ice and frost form on objects such as trees and wires along the surface of the river due to this mist. These ice particles are also formed from supercooled water droplets, which are carried by air currents. These water droplets are smaller than those forming snow crystals, called ice crystals. As they strike and freeze onto objects, many gaps are left between them, resulting in an entirely transparent white appearance. The ice is light and white, and it forms in a beautiful and elegant manner when it attaches to trees.
The phenomenon of frost and ice formation on trees in Jilin City has gained fame throughout East Asia for its unique beauty and charm. Its rarity makes it a popular tourist destination in Jilin City.
