Which set of conditions is most characteristic of unstable air?
- A.Flat stratus, steady drizzle, and persistent fog
- B.Calm winds and a strong temperature inversion
- C.Cumulus clouds, showery precipitation, turbulence, and generally good visibility between showers
Correct answer
C. Cumulus clouds, showery precipitation, turbulence, and generally good visibility between showers
Why
Unstable air rises readily, building cumulus and producing gusty, showery weather. Visibility outside the showers is often good because vertical mixing clears haze.
