Under what circumstances will advection fog come into being, and in which cities will this scene appear?

In our daily life, the scenes of nature are colorful, and there is a unique scene of nature, that is, although the appearance of things in daily life brings inconvenience to our lives, the formation of fog is very beautiful, especially in advection fog, and its landscape is very spectacular.

You know, advection fog usually appears in winter or autumn, and advection fog may appear at any time in winter or autumn, provided that it will not disappear all day, sometimes lasting for hundreds of kilometers, and the radiation intensity of advection is greater than that of ordinary fog. Advection is often accompanied by a series of weather phenomena such as stratus clouds or rain, while advection fog often appears at sea or coastal areas.

And advection fog will also happen in some cities in China, such as Qingdao. Due to the unique geographical features of Qingdao, it is foggy all year round, and advection fog is one of them. When Qingdao comes to stay, we just need to stand on the tall building and look into the distance, then we can see any tall building, only the top of it is exposed.

Although the scenes made in advection fog are very beautiful, advection fog is also harmful to our human health. When advection fog appeared, it would make the air contain a lot of harmful substances, causing air pollution, and this series of chemistry would make the air filled with a harmful substance, which is very fatal to our human health.

Moreover, we also need to know that advection fog is mainly formed by some kind of weather, which is often formed by low-altitude warm and wet moving to the icy sea surface, so it is difficult for advection fog to make a short-term forecast. So we often see advection fog from unexpected places.
