Is it cold in foggy weather?

According to China Meteorological Network, the smog weather is caused by the high relative humidity of the air near the ground and the high dust on the ground, which is stirred up by people and traffic on the ground. This kind of weather only weakens the solar radiation during the day, resulting in a lower temperature during the day than when there is no smog, but it is not cold.

There is no obvious cold air activity at night, the wind is small and the atmosphere is relatively stable. Because the air does not flow, smog can enhance the atmospheric inverse radiation, making the temperature higher at night than when there is no smog, so the temperature difference between day and night is smaller when there is smog than when there is no smog, and it will not be very cold.
