Thermal Inversion Under normal circumstances, temperature usually decreases with height. Colder up above, and warmer near Earth’s surface. With thermal inversion, otherwise known as temperature inversion, these usual troposphere temperatures are reversed, with cold air being trapped under a layer of warmer air near the surface. These temperature inversions play a major role in the quality of air and only encourage air pollution to build up to unhealthy levels. Pollution in our world is already bad enough, and with this thermal inversion phenomenon, it only gets worse during the colder months, especially for those more susceptible than average to the threats that pollution poses. Although it has a larger effect on those with preexisting conditions, thermal inversion can lead to respiratory problems to those without them. During inversion season, to help aid in the protection of air quality, we can do what we normally should to help diminish pollution. Driving less, taking public transportation, walking, and more can help with the reduction of vehicle emissions being emitted into our atmosphere. We can also be more mindful when burning things; being aware of what we’re burning or when we’re burning can help increase air quality.
