Based on the three-cell model of global circulation, surface winds "diverge" in the vicinity of: Group of answer choices

Complete question:

Based on the three-cell model of global circulation, surface winds diverge in the vicinity of

The equator

Explanation:

Unequal warming of the atmosphere results in big convective cells of atmospheric circulation: Hardley cell, Ferrel cell, and Polar cell.

The term convective cell refers to air getting warm, expanding, getting less dense, and ascending. As it ascends, it gets colder because of the change in high, it contracts, gets denser, and hence descends.

In each hemisphere, warm air ascends at the equator and approximately at 60º latitude. Cold air descends at approximately 30º latitude and at the poles. These air masses circulation generates superficial winds that blow toward the equator between 0º-30º latitude and toward the poles between 30º-60º latitude.

Hardley cell occurs between 0º and 30º latitude (north and south). While the tropical air gets warmer, it ascends and produces a low atmospheric pressure area over the equator. The dense air that is coming from the north and south, moves to the area of low pressure resulting in the formation of superficial winds that blow toward the equator.

Meanwhile, the warmed air that ascended, gets denser and is pushed by the new mass of warm air that also elevates getting away from the equator. This occurs in both hemispheres, so the equator is the divergence point where warm masses of air ascend and get separated as they get colder and pushed.  

When these masses of air get cold enough, they descend again approximately al about 30º latitude (north and south). This is the horse´s latitude. And the cycle starts all over again.  

Ferrel cell occurs between 30º and 60º latitude, and the polar cell occurs between 60º and the poles.

the answer is b. hope this !
