Mo9-L4b: How is Air Circulation Created?
As warm air rises rapidly in the atmosphere, it cools to form large, tall clouds.
Latent heat, released as water vapor, changes from a gas to a liquid, adds to the instability, and produces a
thunderstorm.
A temperature inversion occurs in the troposphere when temperature increases as altitude increases.
During a temperature inversion, a layer of cooler air is trapped by a layer of warmer air above it.
SUMMARY
How is Air Circulation Created?
Temperature inversions prevent air from mixing and can trap pollution in the air close to Earth’s
surface.
