Final answer:
When the environment lapse rate is greater than the dry adiabatic rate, the air exhibits a temperature inversion.
Step-by-step explanation:
When the environment lapse rate is greater than the dry adiabatic rate, the air exhibits a temperature inversion.
In meteorology, a temperature inversion is a deviation from the normal change of atmospheric temperature with altitude. Normally, air temperature decreases with an increase in altitude, but during a temperature inversion, warmer air is held above cooler air, causing the normal temperature profile to be inverted.
This phenomenon can occur when a layer of colder air is trapped near the Earth's surface by a layer of warmer air above it. The presence of an inversion can have significant impacts on weather patterns and can lead to the formation of fog, smog, and other atmospheric conditions.
