What effect does a thermal inversion have on air pollutants?

A thermal inversion can have a significant impact on air pollutants. In a thermal inversion, a layer of warm air traps cooler air and pollutants below it, preventing them from dispersing and diluting in the atmosphere. This can lead to the buildup of pollutants and smog at ground level, resulting in poor air quality and potential health issues for those living in the area.

Additionally, thermal inversions can also prevent vertical mixing of the atmosphere, which is needed for pollutants to be carried away and dispersed. This can result in high concentrations of pollutants staying close to the ground for an extended period of time, further exacerbating air quality issues.

Overall, a thermal inversion can lead to increased levels of air pollutants, lower air quality, and potential negative impacts on human health and the environment.
