What forms when cool air descends from the mountain peaks?

When cool air descends from mountain peaks, it often leads to the formation of a temperature inversion, where the cooler air traps warmer air below. This can create a stable atmosphere that inhibits cloud formation and precipitation. Additionally, the descending air can warm adiabatically, leading to the development of clear skies and dry conditions in the valleys below, a phenomenon known as a rain shadow effect.
