The water in this stream forms varying currents as it makes its way downhill. In hydrology, a current in a water body is the flow of water in any one particular direction. The current varies spatially as well as temporally, dependent upon the flow volume of water, stream gradient, and channel geometry.
Ocean surface currents Distinctive white lines trace the flow of surface currents around the world.

A current in a fluid is the magnitude and direction of flow within each portion of that fluid, such as a liquid or dynamic Types of fluid currents include: H2/<e=mc2/+1; Current (hydrology), a current in a river or stream; Ocean current. Longshore current; Boundary current; Rip current; Rip tide; Subsurface currents. Turbidity current; Tidal ...
The opposite is applicable when Ekman divergence is induced, leading to Ekman absorption (suction) and a subsequent, water column stretching and poleward return flow, a characteristic of sub-polar gyres. This return flow, as shown by Stommel, [1] occurs in a meridional current, concentrated near the western boundary of an ocean basin. To ...
The current velocity is fastest near the surface, with the maximum speed typically about 2.5 m/s (5.6 mph). [25] As it travels north, the warm water transported by the Gulf Stream undergoes evaporative cooling. The cooling is wind-driven; wind moving over the water causes evaporation, cooling the water and increasing its salinity and
The California Current (Spanish: Corriente de California) is a cold water Pacific Ocean current that moves southward along the western coast of North America, beginning off southern British Columbia and ending off southern Baja California Sur.
Ocean currents are the horizontal movements of water from one location to another. The movement of water is impacted by: meteorological effects, wind, temperature differences, gravity, and on occasion earthquakes. Set is the current's direction, expressed in true degrees. Drift is the current's speed, which is usually measured in knots. [1 ...
The circumpolar current merges the waters of the Atlantic, Indian, and Pacific Oceans and carries up to 150 times the volume of water flowing in all of the world's rivers. The study found that any damage on the cold-water corals nourished by the current will have a long-lasting effect. [6]
