thermal inversion

**thermal inversion**

Thermal inversion is a meteorological phenomenon where a layer of warm air traps cooler air near the Earth’s surface, preventing it from rising. This reversal of the typical temperature gradient can lead to increased air pollution and smog, as pollutants become trapped close to the ground. Thermal inversions often occur in valleys or during calm, clear nights and can have significant impacts on local weather conditions and air quality. Understanding thermal inversion is important for environmental science, weather forecasting, and public health awareness.
