What kind of meteorological conditions are conducive to the dilution and diffusion of pollutants and reduce the degree of air pollution?

For example, in winter, under the control of stable high pressure, the weather is generally sunny and the wind is not strong.

Sooner or later, it is easy to form inversion near the ground, when pollutants in the air stay near the ground and are easy to form pollution.

However, under the control of low air pressure or before cold high pressure, the wind is often strong and pollutants are easy to spread, so it will not cause air pollution.
