Wind and Ocean Currents: �Heat Movers�<span>Both air currents and ocean currents move heat. Energy is stored as "latent heat" in the atmosphere. In the surface waters of the ocean it is stored as "sensible heat." Atmospheric and oceanic circulation share the task of<span>heat </span>redistribution on a roughly fifty-fifty basis. Even though transfer of heat by moving water in ocean currents is much less efficient than transfer by moving vapor in wind, the masses involved are much greater in the ocean currents than in the air currents.
