What is a temperature inversion?
- A.A layer where temperature falls twice as fast as the standard rate
- B.A condition found only inside a thunderstorm
- C.A layer where temperature increases with altitude instead of decreasing
Correct answer
C. A layer where temperature increases with altitude instead of decreasing
Why
An inversion reverses the normal lapse rate and acts like a lid on vertical mixing. It is often associated with stable air, trapped haze or smoke, and poor visibility below the inversion.
