    Eddies normally travel around one mile per day in these areas; the smoke rings covered five to 10 miles per day and lasted for about six months before splitting up.

  3. Eddy pumping - Wikipedia

    en.wikipedia.org/wiki/Eddy_pumping

    Cyclonic eddies rotate anticlockwise (clockwise) in the Northern (Southern) hemisphere and have a cold core. Anticyclonic eddies rotate clockwise (anticlockwise) in the Northern (Southern) hemisphere and have a warm core. The temperature and salinity difference between the eddy core and the surrounding waters is the key element driving vertical ...

  4. Loop Current - Wikipedia

    en.wikipedia.org/wiki/Loop_Current

    A related feature is an area of warm water with an "eddy" or "Loop Current ring" that separates from the Loop Current, somewhat randomly every 3 to 17 months. [4] Swirling at 1.8 to 2 meters/second, these rings drift to the west at speeds of 2 to 5 kilometers/day and have a lifespan of up to a year before they bump into the coast of Texas or ...

  5. Ocean gyre - Wikipedia

    en.wikipedia.org/wiki/Ocean_gyre

    In oceanography, a gyre (/ ˈ dʒ aɪ ər /) is any large system of ocean surface currents moving in a circular fashion driven by wind movements. Gyres are caused by the Coriolis effect; planetary vorticity, horizontal friction and vertical friction determine the circulatory patterns from the wind stress curl ().

  6. North Atlantic Gyre - Wikipedia

    en.wikipedia.org/wiki/North_Atlantic_Gyre

    View of the currents surrounding the gyre. The North Atlantic Gyre of the Atlantic Ocean is one of five great oceanic gyres.It is a circular ocean current, with offshoot eddies and sub-gyres, across the North Atlantic from the Intertropical Convergence Zone (calms or doldrums) to the part south of Iceland, and from the east coasts of North America to the west coasts of Europe and Africa.

  7. Geostrophic current - Wikipedia

    en.wikipedia.org/wiki/Geostrophic_current

    A geostrophic current is an oceanic current in which the pressure gradient force is balanced by the Coriolis effect. The direction of geostrophic flow is parallel to the isobars , with the high pressure to the right of the flow in the Northern Hemisphere , and the high pressure to the left in the Southern Hemisphere .

  8. Antarctic Circumpolar Current - Wikipedia

    en.wikipedia.org/wiki/Antarctic_Circumpolar_Current

    Alternatively, ocean eddies, the oceanic equivalent of atmospheric storms, or the large-scale meanders of the Circumpolar Current may directly transport momentum downward in the water column. This is because such flows can produce a net southward flow in the troughs and a net northward flow over the ridges without requiring any transformation ...

  9. Kuroshio Current Intrusion - Wikipedia

    en.wikipedia.org/wiki/Kuroshio_Current_Intrusion

    The Kuroshio Current is a northward flowing Western Boundary Current (WBC) in the Pacific Ocean. It is a bifurcation arm of the North Equatorial Current and consists of northwestern Pacific Ocean water. The other arm is the southward flowing Mindanao Current. The Kuroshio Current flows along the eastern Philippine coast, up to 13.7 Sv...
