Temperature inversions work to trap pollution when the temperature increases with height instead of decreasing. In a temperature inversion, a layer of warm air is trapped above a layer of cooler air, which acts like a lid and prevents the mixing of air and the dispersal of pollutants. This can lead to the accumulation of pollutants near the surface, resulting in increased air pollution.
Temperature inversions are more likely to occur in calm, stable weather conditions, such as clear nights with light winds, when the ground cools faster than the air above it. The trapped pollutants can cause a range of health and environmental problems, including respiratory issues, smog, and haze.
It is important to note that temperature inversions are not the only factor that can cause air pollution. Other factors, such as emissions from industrial processes, transportation, and deforestation, also play a significant role in air pollution.
