The physical ...
As wind moves across the surface of the ocean, friction between moving air and the water surface causes water to begin to move as well. This transfer of energy by friction is how wind causes surface currents. Once water at the surface begins to move, some energy gets transferred to deeper ...
Previous studies have suggested that the intraseasonal zonal current in the western basin is caused by oceanic internal instabilities (Schott et al., 2009; Sengupta et al., 2001), specifically from gyres in the Somali current (Brandt et al., 2003). Herein, our results reveal that even in ...
Wind-Driven Ocean Circulation Steady winds produce waves and set the surface water in motion Moving water is deflected to the right (N.Hemisphere) or left (S.Hemisphere) This starts the main “gyre” motion of the surface ocean Surface Ocean Circulation Main Features Five large gyres Antarctic ...
drifts in the surface currents of the world's oceans and either sinks to the bottom of the ocean, beaches itself (Maximenko et al., 2012), or accumulates in ocean convergence zones, such as the “Great Pacific Garbage Patch” (Howell et al., 2012) or centers of other subtropical gyres....
the data withEa>0.1 m2 s−2can reach 40–50% within the strong-current regions; and in the subtropical gyres, about 20–30% data points have large enough ageostrophic energy to lead to a chlorophyll increase (Supplementary Note1). When compared with the ageostrophic kinetic energy,...
The dataset utilized in this model depends on campaigns from 2007 to 2013 (Table 1), studying every one of the five subtropical gyres (North Pacific, North Atlantic, South Pacific, South Atlantic, Indian Ocean) and broad waterfront locales and encased oceans (Bay of Bengal, Australian coasts ...
[1] Surface drifters deployed in the subtropical and subpolar North Atlantic from 1990 to 2002 show almost no connection between the subtropical and subpolar gyres; only one drifter crosses the intergyre boundary even though other data types (e.g., dynamic topography and tracers) suggest a majo...
Do surface currents or deep currents pass through a hurricane? Is the Turkestan desert hot or cold? Which two continents are north of the equator? Is ocean salinity high in the subtropical gyres? What is the average temperature in the polar zones? Do deep ocean currents affect surface cur...
Based on buoy and hydrographic data, large-scale movement of upper water between subpolar and subtropical gyres is week, flow- ing slowly towards east and south46. However, a poleward surface current has been reported off the west coast of Portugal during winter when the wind blowing northward...
