How do weather patterns influence air quality?

Weather patterns play a crucial role in influencing air quality by impacting the distribution and concentration of pollutants in the atmosphere. When weather conditions are favorable, such as during strong winds or rain, they can help disperse air pollutants, thereby improving air quality. Conversely, certain weather patterns, like temperature inversions or stagnant air conditions, can trap pollutants near the ground, leading to higher concentrations of harmful substances and deteriorating air quality.

This dynamic interplay means that air quality is not merely a product of emission sources, but also highly influenced by the prevailing weather conditions. For example, in urban areas during the summer, heat can create smog, whereas windy conditions might help clear the air. Therefore, the assertion that weather patterns can either disperse pollutants or trap them close to the ground is a comprehensive explanation of how these patterns affect local air quality conditions.
