How is the smog formed? What are the hazards?

Haze formation: Fog refers to the weather phenomenon when the visibility is lower than 1 km due to the condensation of water vapor suspended in the atmosphere. The formation of smog is mainly the result of the interaction between a large number of suspended particles in the air and meteorological conditions. There are three reasons for the smog weather: 1, and the phenomenon of increasing static wind in the horizontal direction. 2. There is an inversion in the vertical direction. 3. The increase of suspended particles in the air.

Hazards of smog

1, affecting life

Haze weather has an important impact on roads, railways, aviation, shipping, power supply systems and crop growth. Fog and haze will cause air quality decline, affect the ecological environment and bring great harm to human health.

2. Affect traffic

Due to the poor air quality and low visibility in foggy days, rear-end collision accidents are prone to occur, which will affect the normal traffic order and have no change in everyone's travel. We should observe the road conditions more during daily driving to avoid danger.
