Temperature inversions occur when a layer of warm air traps cooler air near the ground. In this scenario, instead of the typical conditions where warm air rises and disperses pollutants, the warm layer acts as a lid. This trapping effect prevents pollutants, such as industrial emissions and vehicle exhaust, from dispersing into the atmosphere. As a result, the accumulation of these pollutants can lead to deteriorating air quality in the affected area.

This phenomenon is particularly problematic in urban environments or areas with high levels of emissions, as it can lead to the buildup of smog and other harmful air pollutants. Air quality can deteriorate significantly, contributing to health issues for vulnerable populations, such as those with respiratory conditions. Overall, understanding the role of temperature inversions is crucial in addressing air quality management and public health issues.
