What effect do temperature inversions have on air quality?

Temperature inversions significantly impact air quality because they create a stable layer of warm air above a cooler layer near the surface. This condition prevents the normal upward movement of air, which would typically allow pollutants to disperse into the atmosphere. Instead, the cooler air trapped at the surface becomes stagnant, causing any pollutants—such as smoke, soot, and gases—to accumulate close to the ground. As a result, the concentration of harmful substances increases, leading to poorer air quality and potential health risks for those exposed. This phenomenon is particularly common in urban areas and during certain weather conditions, emphasizing the importance of monitoring air pollution levels during temperature inversion events.
