Explanation:
Detailed explanation-1: -As convection from solar heating causes hot air to rise along the equator, that air is replaced with air from the north and south.
Detailed explanation-2: -At the doldrums, the warm air rises and flows away from the equator to about 30 degrees south and north latitude where it descends respectively. From this wind, some of the warm air moves towards the westward direction in the form of trade winds.
Detailed explanation-3: -The trade winds can be found about 30 degrees north and south of the equator. Right at the equator there is almost no wind at all-an area sometimes called the doldrums.
