When will the fog dissipate?

Fog needs too much moisture in the air to form fog, so it is easy to form fog in autumn and winter. The reason why fog dissipates can be that the surface temperature rises, which leads to fog evaporation, or that the wind speed increases, which leads to fog being blown into clouds.

Fog usually begins to fog after eleven o'clock in the evening to around two o'clock in the morning, and will disperse around ten o'clock the next morning. However, during the heavy fog, expressway will implement grade control to avoid delaying the planned events and arrange the travel time reasonably.

Fog introduction

Fog refers to the weather phenomenon that there are countless small water droplets or small ice crystals suspended in the air near the ground, resulting in horizontal visibility less than 500 meters. A large number of small water droplets or ice crystal particles are suspended in the air near the lower level, which makes people's vision blurred. When the horizontal energy distance of relevant personnel drops below 1000 meters, it is called fog.

It will also cause changes in insulators of transmission lines and open-air electrical equipment, and even lead to accidents and harm human health. Affect visibility and easily cause traffic accidents. Now scientists believe that due to the existence of the "inversion layer", the atmosphere is very stable, convection is weakened, and pollutants such as water vapor and dust in the air are not easy to spread to high altitude.
