is a term that has been used to denote all time-varying mesoscale ocean phenomena such as planetary waves and oceanic vortices Some authors reserve the use of this term for closed circulation features like Gulf Stream and rings and other mesoscale vortices
Motion of a fluid in directions differing from, and at some points contrary to, the direction of the larger-scale current
An eddy is a movement in water or in the air which goes round and round instead of flowing in one continuous direction. eddies a circular movement of water, wind, dust etc. eddied eddying eddies if water, wind, dust etc eddies, it moves around with a circular movement
A circular movement of water or air that is formed where currents pass obstructions or between two adjacent currents that are flowing counter to each other (Source: Carbon Dioxide Information Analysis Center, 1990)
a miniature whirlpool or whirlwind resulting when the current of a fluid doubles back on itself founder of Christian Science in 1866 (1821-1910) flow in a circular current, of liquids
A small volume of air that behaves differently from the predominant flow of the layer in which it exists, seemingly having a life of its own An example would be a tornado, which has its own distinct rotation, but is different than the large-scale flow of air surrounding the thunderstorm in which the tornado is born

A circular movement of water, usually formed where currents or tidal streams pass obstructions, along the edge of a current or stream, or between two adjacent flows
A small disturbance of wind in a large wind flow, which can produce turbulent conditions They can also be areas of warmer air north of the main westerlies or colder air south of the westerlies In oceanic circulation, it is a circular movement of water usually formed where currents pass obstructions, between two adjacent currents flowing counter to each other, or along the edge of a permanent current
A small disturbance of wind in a large wind flow, which can produce turbulent conditions or turbulence They can also be areas of warmer air north of the main westerlies or colder air south of the westerlies (See cut-off high or cut-off low ) In oceanic circulation, it is a circular movement of water usually formed where currents pass obstructions, between two adjacent currents flowing counter to each other, or along the edge of a permanent current
A relatively calm area, away from the main current, often near the shore Upstream gates are often located in eddies, so that the paddler will not have to fight the current's full force
An area of water that is still, slow-moving, or moving upstream behind an obstacle in a river Often used by white water paddlers to stop and look about
An indentation found in a body of water where a smaller body of water swirls back into itself It is created when a current cuts into a bank Food usually collects in this area, which attracts fish
