How do weather conditions affect air quality ?

How do weather conditions affect air quality ?

Weather conditions significantly affect air quality by influencing the dispersion, accumulation, and transformation of pollutants. High temperatures can increase ozone levels, while low temperatures can trap pollutants near the ground. Wind helps disperse pollutants, improving air quality, but calms can lead to pollutant buildup. Precipitation, like rain and snow, can wash pollutants from the air. High humidity promotes ozone formation but aids in particle removal, whereas low humidity inhibits some pollutants and suspends dust. Temperature inversions trap pollutants, degrading air quality, while cold fronts and storms can clean the air through winds and precipitation.
