Question

which of the following statements regarding wind patterns is accurate?
a dry, cold winds that originate from the north pole and south pole are called trade winds.
b most tropical storms start as prevailing westerlies.
c the polar easterlies flow toward both the north pole and south pole.
d the prevailing westerlies are strongest in the winter

Explanation:

Trade winds are found near the equator, not originating from the poles, so A is incorrect. Tropical storms do not start as prevailing westerlies, so B is incorrect. Polar easterlies flow away from the poles, not toward them, so C is incorrect. Prevailing westerlies are strongest in winter due to larger temperature gradients.

Answer:

D. The prevailing westerlies are strongest in the winter
