Convention Current Research Paper

Winds – The single biggest factor in the creation of surface currents is the wind. The surface of the water is generally smooth and calm, when strong winds move across the water the surface moves. The winds most often associated with the creation of ocean currents are the Westerlies, which blow west to east and the Trade Winds, which blow east to west.
Salinity – The higher the salinity of the water the more dense it becomes. With a high level of salinity the water will sink. This starts a convention current. A convention current is when the cold water sits on top of the warm water (depending on the salinity level), and the flow of the current can be reversed if the density and salinity combined with temperature of the water changes.
