The movement of air in major wind currents has a significant influence in determining how water moves. Wind actually causes water to move in similar directions, creating surface currents. Surface currents are then deflected based on the rotation of the Earth due to the Coriolis Effect. There are various major surface currents in the ocean, and these surface currents have effects on climates around the world. There are also other currents, such as counter currents, undercurrents, monsoon currents, and El Niño and the Southern Oscillation. All of these surface ocean currents play an important role in transferring warm and cold water across the world.
