Surface ocean currents are driven mainly by winds and are affected by seasons.Deep ocean currents are driven mainly by density and temperature gradients. However the most important and fundamental causes for the formation of the ocean currents are solar heating,winds and gravity. Source(s): Arasan Â· 9 years ago.
Ocean currents are one of the main factors that affect climate. Other factors are proximity from the equator, distance from the sea, direction of prevailing winds and relief (mountains). But, for the most part, ocean currents act as one of the most important factors that influence the climate. And the reason why is because a current is water that travels. With that traveling water comes heat. The best example of a current is the Gulf Stream. This is a current of water that originates in the Gulf of Mexico and heads north in the Atlantic toward Western Europe and The United Kingdom. It then circles around and goes back to the Gulf. A current, therefore, is water that goes in a cycle.
