Extended information:

In winter mornings, the surface temperature is low and the air temperature is high. Temperature inversion often occurs, causing the atmosphere to stop up and down convection activities. There is also exhaust gas emitted by cars, which contains pollutants such as carbon monoxide, hydrocarbons, and lead. Various harmful substances gather on the ground and cannot diffuse to the upper layers of the air. They deposit and stay near people's respiratory tracts, causing people to inhale more smoke and dust. and toxic gases.
