From the equator, hot water pushes outward to the north and south pole. 8 (q) Surface and Subsurface Ocean Currents - Geography When water heats, water molecules vibrate faster and eventually move farther apart. At the equator, the sun heats water the strongest. Wind blowing across a body of water transfers some of its momentum onto the surface of the water, causing it to move. At the surface, aspects of wind-driven circulation cause the gyres (large anticyclonic current cells that spiral about a central point) to displace their centres westward, forming strong western boundary currents against the eastern coasts of the continents, such as the Gulf Stream-North Atlantic-Norway Current in the Atlantic Ocean and the Kuroshio-North Pacific Current in the Pacific .
