Which mechanism drives surface ocean currents in the tropics due to Hadley cell dynamics?

💡 Explanation

When Hadley cells rise at the equator and descend at 30 degrees latitude, surface winds are created as air moves to lower pressure; therefore trade winds exerting drag on the ocean surface drive currents rather than Ekman transport, upwelling, or geostrophic balance that involve varying different mechanisms.
