weather theoryFAA-published sample question (ATM, Aug 2021)
What weather phenomenon can be associated with the tropopause?
A
A constant temperature lapse rate.
B
Clear air turbulence associated with the jet stream.✓ Correct Answer
C
The deflection of air currents to the right.
Explanation
The jet stream is found near breaks in the tropopause, and strong wind shear there produces clear air turbulence. The tropopause is marked by an abrupt change in lapse rate (to nearly constant temperature above), not a constant lapse rate, and deflection to the right is the Coriolis effect.
