NettetInversion can influence pollution near the ground as well as the behaviour of smoke leaving a chimney. Under normal conditions, smoke plumes from chimneys would rise … NettetAn inversion is formed when a ceiling of warmer air traps the cooler layer of air, which contains the pollutants, near the ground’s surface. This hinders the ability of the pollutants to rise to the atmosphere and be dispersed. After an inversion has formed, it keeps any smog that is present close to the ground, maximising its detrimental effect.

NettetAn inversion traps air pollution, such as smog, close to the ground. An inversion can also suppress convection by acting as a "cap.". If this cap is broken for any of several reasons, convection of any moisture present can then erupt into violent thunderstorms. Temperature inversion can notoriously result in freezing rain in cold climates.
