How ocean currents form
NettetThis is a map ocean surface currents from 1877. (John James Wild, 1877) At the surface, currents are mainly driven by four factors—wind, the Sun’s radiation, gravity, and Earth’s rotation. All of these factors are interconnected. The Sun’s radiation creates prevailing wind patterns, which push ocean water to bunch in hills and valleys. Nettetmap.

NettetOcean circulation derives its energy at the sea surface from two sources that define two circulation types: (1) wind-driven circulation forced by wind stress on the sea surface, … Nettetdensity current, any current in either a liquid or a gas that is kept in motion by the force of gravity acting on differences in density. A density difference can exist between two fluids because of a difference in temperature, salinity, or concentration of suspended sediment. Density currents in nature are exemplified by those currents that flow along the …
