Question

Why does thermal inversion increase air pollution? What harm can thermal inversion cause to humans?

Answer 1

Thermal inversion also known as Temperature inversion is a phenomenon in which a relatively warm layer of air is formed in the mid altitude and above and below which is a cooler air is present. Under normal conditions the temperature of air decreases in a uniform proportion with increasing altitude. Due to formation of this warm layer in the middle, the emissions (pollutants) from the factories and automobiles gets trapped under the inversion layer and results in increased air pollution.
