Which level does the mid-latitude westerly maximum occupy?
Answer: C
Westerly shear accumulates upward through the whole troposphere while the temperature gradient persists, so the wind reaches its maximum where that gradient reverses, which is at the tropopause. Above it the temperature gradient changes sign and the westerlies weaken again. The surface gradient may be sharp, but shear must be integrated over depth to produce a strong wind, which is precisely why the jet sits high rather than low. Checking the units of each quantity catches a wrong formula before the arithmetic begins.
