weather theoryFAA-published sample question (IRH, Aug 2021)
What is an important characteristic of wind shear?
A
It is an atmospheric condition that is associated exclusively with zones of convergence.
B
The Coriolis phenomenon in both high and low level air masses is the principal generating force.
C
It is an atmospheric condition that may be associated with a low level temperature inversion, a jet stream, or a frontal zone.✓ Correct Answer
Explanation
Wind shear can occur at any altitude and is associated with low-level temperature inversions, the jet stream, frontal zones and thunderstorms, as PHAK Chapter 12 explains. It is not limited to convergence zones, and the Coriolis force is not its principal cause.
