Jet streams can split into two when they encounter an upper-level low, that diverts a portion of the jet stream under its base, while the remainder of the jet moves by to its north. The wind speeds are greatest where temperature differences between air masses are greatest, and often exceed 92 km/h (50 kn; 57 mph). [ 22 ]
Thermohaline circulation. Thermohaline circulation (THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. [1][2] The adjective thermohaline derives from thermo- referring to temperature and -haline referring to salt content, factors which together determine ...
The Atlantic meridional overturning circulation (AMOC) is the main current system in the Atlantic Ocean, [1]: 2238 and is also part of the global thermohaline circulation, which connects the world's oceans with a single "conveyor belt" of continuous water exchange. [29] Normally, relatively warm, less-saline water stays on the ocean's surface ...
Atmospheric circulation. Atmospheric circulation is the large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth. The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant.
The Atlantic jet stream is a fast and narrow current of air flowing from west to east and encircling the globe and is widely used by airplanes traveling east from North America to cut down on ...
The Hadley cells may extend to around 60° latitude, equatorward of a mid-latitude jet stream demarcating the boundary between the hypothesized Hadley cell and the polar vortex. [133] The planet's atmosphere may exhibit two Hadley circulations, with one near the surface and the other at the level of the upper cloud deck.
The California Current (Spanish: Corriente de California) is a cold water Pacific Ocean current that moves southward along the western coast of North America, beginning off southern British Columbia and ending off southern Baja California Sur. It is considered an Eastern boundary current due to the influence of the North American coastline on ...
North Atlantic Current. 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.
