Inversions
Normally, air temperature decreases as altitude increases.
An inversion occurs when the opposite happens and temperature increases with height through a layer of the atmosphere.
This means there is warmer air above cooler air.
An inversion is a very stable layer because the cooler, denser air below resists rising through the warmer air above.

Conditions below the inversion are generally stable.
This can cause:
