weather theoryFAA-published sample question (ADX, Aug 2021)

Which type clouds may be associated with the jetstream?

A

Cumulonimbus cloud line where the jetstream crosses the cold front.

B

Cirrostratus cloud band on the polar side and under the jetstream.

C

Cirrus clouds on the equatorial side of the jetstream.✓ Correct Answer

Explanation

The Aviation Weather Handbook notes that cirriform clouds associated with the jet stream typically lie on its equatorial side, where rising air feeds high-level moisture. The cloud band is not on the polar side, and a cumulonimbus line is a frontal feature, not a jet stream indicator.
