The North Atlantic Current is the first leg in the North Atlantic Subpolar Gyre. The North Atlantic Current (NAC), also known as North Atlantic Drift and North Atlantic Sea Movement, is a powerful warm western boundary current within the Atlantic Ocean that extends the Gulf Stream northeastward.
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.
While the Gulf Stream as a whole is driven by winds alone, its northern-most segment, the North Atlantic Current, obtains much of its heat from thermohaline exchange in the AMOC. [3] Thus, the AMOC carries up to 25% of the total heat toward the northern hemisphere, [33] and plays an important role in the climate around northwest Europe. [34]
A vital system of Atlantic Ocean currents that influences weather across the world could collapse as soon as the late 2030s, scientists have suggested in a new study — a planetary-scale disaster ...
Surface temperatures in the western North Atlantic: Most of the North American landmass is black and dark blue (cold), while the Gulf Stream is red (warm). Source: NASA The Gulf Stream is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States, then veers east near 36°N latitude ...
The Atlantic Meridional Overturning Circulation (the AMOC) — of which the Gulf Stream is part — works like a giant global conveyor belt, taking warm water from the tropics toward the far North ...
A system of ocean currents that transports heat northward across the North Atlantic could collapse by mid-century, according to a new study, and scientists have said before that such a collapse ...
The Gulf Stream separates from the US coast near Cape Hatteras (35°N, 75°W) and then travels eastwards across the North Atlantic, becoming the North Atlantic current at about 55°W. In the region between 75°W and 55°W it is subject to meanders and is frequently accompanied by eddies. The northern edge of the current is marked by a sharp ...
