Inverse temperature is a phenomenon of vertical stratification in the atmosphere where air temperature increases with altitude.
The phenomenon of atmospheric inversion directly affects the diffusion of atmospheric pollutants.
Generally speaking, the inversion layer is stronger and thicker in winter and lasts longer, while it is weaker in summer.
Usually there is a temperature inversion phenomenon in the clear and breezy night, which makes the lower atmosphere more stable and is very harmful to the diffusion of pollutants.
After the sun rises, with the increase of surface temperature, the inversion layer disappears gradually, atmospheric turbulent mixing and vertical convection are strengthened, which contribute to the diffusion of pollutants.
