Answer :
The correct answer is B) Polar easterlies that curve due to air above equator being relatively warmer.
What best describes these winds is Polar easterlies that curve due to air above equator being relatively warmer.
Here we can see the air shown as a circle. The equator is at zero degrees. Curved arrows at the top and the bottom point to the circle toward 60 degrees south and north latitude. The cold air comes from the Noth pole and the south pole, creating high pressure. The polar easterlies are cold and dry, irregular and weak winds. These are winds from the polar highs atmospheric pressure.
