The eastward flowing current that originates from the Gulf Stream Extension east of the Grand Banks (about 40°N, 50°W). It initially forms part of the Atlantic subtropical gyre but separates from it after less than 500 km near 45°W, turning northeastward and following the Arctic Polar Front, also known as the North Wall, with a transport of some 30 Sv (30 × 10<sup>6</sup> m<sup>3</sup>s<sup>−1</sup>). Some of this water enters the subpolar gyre through mixing across the polar front and feeds the Irminger Current, but most of it is delivered to the Norwegian Current. The North Atlantic Current carries warm subtropical water much farther north than any other current of the Northern Hemisphere. As a result the climate of northern Europe is much milder than the climate of Alaska or northern Siberia, both of which are located at comparable latitude.

A water mass found in the Atlantic at depths between 1000 and 4000 m that can be traced from there into most other ocean basins. It is formed in the North Atlantic from some 5 Sv (5 × 10<sup>6</sup> m<sup>3</sup>s<sup>−1</sup>) of Atlantic Bottom Water entering through Denmark Strait and across the Scotland–Faeroe–Iceland Ridge. This water flows toward the Labrador Sea, entraining another 5 Sv from the eastern North Atlantic on its way. Another 5 Sv is added in the Labrador Sea by winter convection, giving a total of 15 Sv of NADW formation. The NADW formation process is the engine of the ocean conveyor belt, which makes NADW one of the most important water masses for today's climate.

One of the western boundary currents of the Atlantic Ocean and part of the pathway for water from the Southern into the Northern Hemisphere in the global ocean conveyor belt. Flowing northward along the coast of northern Brazil with speeds up to 0. 8 m s<sup>−1</sup>, it originates from the South Equatorial Current and continues as the Guyana Current.

The broad region of uniform westward flow that forms the southern part of the Northern Hemisphere subtropical gyres driven by the trade winds. Being directly wind driven, the NEC responds quickly to variations in the wind field and is therefore strongest in winter (February). In the Atlantic Ocean it is found between 8° and 30°N with speeds of 0. 1–0. 3 m s<sup>−1</sup>. In the Pacific Ocean it has similar speed but is limited to 8°–20°N. In the Indian Ocean it exists only during December–April when the northeast monsoon produces the same wind forcing as the Northern Hemisphere trade winds. It then runs as a narrow current of 0. 3 m s<sup>−1</sup> from Malacca Strait to Sri Lanka where it bends southward and accelerates in the region 60°–75°E to 0. 5–0. 8 m s<sup>−1</sup> between 2°S and 5°N and continues along the equator.
