The main causes of haze weather.

Smog is very common in cities. Fog and smoke, as a disastrous weather phenomenon, are used as early warning and forecasting in many areas of China, collectively referred to as haze weather. There are two reasons for the formation of haze weather: meteorological reasons and pollution discharge reasons. Experts pointed out that the recent fog in the Middle East is called radiation fog weather in meteorology. The main reasons are as follows: First, the relative humidity of the near-ground air in these areas is relatively high; Second, people and traffic stir up the dust on the ground; Third, there is no obvious cold air activity; Fourth, the atmosphere is relatively stable and the wind is small; Fifth, the air does not flow, which makes the tiny particles in the air gather; Sixth, partly cloudy sunny days are conducive to radiation cooling at night; Seventh, the high surface water temperature makes the surface air saturated and condensed to form fog.
