weather theoryFAA-published sample question (ATS, Aug 2021)
Cumulus clouds often indicate
A
possible turbulence.✓ Correct Answer
B
a temperature inversion.
C
a dry adiabatic lapse rate.
Explanation
Cumulus clouds form in rising convective currents, so they often indicate turbulence at and below their bases (PHAK Chapter 12). An inversion suppresses them, and the dry adiabatic rate is a physical constant, not something a cloud indicates.
