How do surface currents affect the climate of land near which they flow

Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.

Explanation:

and after water is usually warmed by the sun the water temperature raises and then evaporates .
