Definitions:

Temperature Inversion

A meteorological condition where the temperature of the air increases with altitude, contrary to the norm, which can lead to pollution events and smog.

Leeward Side

The side of a mountain or hill sheltered from the wind, usually having a milder climate and receiving less precipitation than the windward side.

Thermal Inversion

A weather condition where a layer of warm air traps cold air and pollutants near the surface of the Earth, often leading to poor air quality.

Stagnant Air

Air that lacks movement or flow, often leading to poor air quality and discomfort in indoor and outdoor environments due to accumulation of pollutants and humidity.
