What is the foggy side?

It means: the water vapor close to the ground floats in the air after being cooled and condensed.

Due to contact with the cold ground, it condenses into small water droplets or ice crystals, which makes the visibility less than one kilometer. This is the so-called "fog". The difference from clouds is that fog is closer to the ground, and sometimes it is not transparent.

Such as: fog, fog, fog gathering (like clouds), fog analysis (fog dispersion), fog cen (fog-shrouded peaks), fog roll (fog dispersion), fog pestle (like deep fog), and fog will gather together (like clouds). Describe it), fog refutation (describe things as colorful and complicated as fog).

Extended data:

The conditions for fog formation are cooling, humidifying and coagulating nodules to increase the water vapor content.

A kind of fog is formed by radiation cooling, which often occurs at night and early morning when the sun is shining, the breeze is light, the water vapor near the ground is sufficient and stable, or there is inversion. Meteorology calls it radiation fog;

The other is that warm and humid air moves horizontally, passing through the cold ground or water surface, and the water vapor in the air is gradually liquefied by cold to form fog, which is called advection fog in meteorology;

Sometimes fog formed by two reasons is called mixed fog. It can be seen that it is late autumn and early winter that can meet these conditions, especially in the morning of late autumn and early winter.

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.
