What are North and south equatorial currents driven by?

The North and South Equatorial Currents are primarily driven by trade winds, which blow from east to west in the tropics. These winds cause surface waters to move in the same direction, creating the equatorial currents. Additionally, the Earth's rotation contributes to the Coriolis effect, which influences the currents' paths as they flow westward across the ocean basins. As these currents approach landmasses, they typically turn poleward, contributing to larger oceanic circulation patterns.
