Why is there fog on the mountain?
Ice fog:
It is a fog composed of a large number of tiny ice crystals suspended in the air, also known as ice crystal fog. Ice fog is common in winter in cold regions. Because the temperature of the atmosphere near the ground is very low, usually below -40℃, water vapor in the air condenses and forms. The color of ice fog is as gray as water vapor fog, and it will be slightly darker if accompanied by haze. At the same time, ice fog is also a sign for people to identify extreme temperatures in extremely cold areas.
Extreme cold weather in winter is a disastrous weather. If it is accompanied by ice fog or snowfall with extremely low visibility, it is more harmful and often leads to road traffic, flight, shipping and other safety accidents. Ice fog is often accompanied by smoke, nitric oxide, sulfur dioxide and other harmful substances. This is because the formed ice fog hinders the diffusion of dust, automobile exhaust and other substances in the urban air, leading to further air pollution.
Extended data:
1, affecting traffic
Fog is one of the weather that has the greatest influence on human traffic activities. The deterioration of visibility in foggy days is easy to cause traffic accidents. In highway traffic accidents, traffic accidents caused by bad weather such as dense fog account for about a quarter of the total, which not only hinders traffic, but also causes great losses to the country and people's lives and property.
2, affecting health
In foggy days, the combination of pollutants and water vapor in the air will make it difficult for pollutants to spread and settle, which makes most pollutants gather at the height where people often move. Moreover, some harmful substances will become more toxic when combined with water vapor, such as sulfur dioxide becoming sulfuric acid or sulfite, chlorine hydrolyzing into hydrogen chloride or hypochlorous acid, and fluoride hydrolyzing into hydrogen fluoride.
