1: 2 1. 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. The adjective thermohaline derives from thermo-referring to temperature and -haline referring to salt content, factors which together determine the density of sea water. Multiple mechanisms conspire to increase the density of surface waters at high latitudes. Thermohaline circulation is a very slow and extremely deep movement of water in the oceans around the world. Cold winds blowing over the oceans chill the waters beneath them. Driven by density and salinity differences-- heating and cooling at the surface (upwelling and downwelling) and freshwater (evaporation/sea ice formation) cause water to move. What is the thermohaline circulation (THC)? Definition: Large-scale density-driven circulation in the ocean, caused by differences in temperature and salinity. The adjective thermohaline derives from thermo- referring to temperature and -haline referring to salt content, factors which together determine the density of sea water.Wind-driven surface currents (such … In the north Atlantic, the thermohaline circulation consists of warm surface water flowing northward and cold deepwater flowing southward, resulting in a net poleward transport of heat. Wasser ist umso schwerer, je salziger oder je kälter es ist – die gleiche Wasserdichte kann also durch verschiedene Kombinationen der Wassereigenschaften zustande kommen. The thermohaline circulation is an important factor in the Earth’s climate because it transports roughly 1015 W of heat poleward into high latitudes, about one quarter of the total heat transport of the ocean/atmosphere circulation system. Eine Thermohaline Zirkulation entsteht im Ozean, wenn der Salzgehalt und die Temperaturen in unterschiedlichen Gebieten unterschiedliche Wasserdichten hervorrufen. Wind Driven Currents. Sea water density depends on temperature and salinity, hence the name thermo-haline. Die Thermohaline Zirkulation ist eine grossräumige Zirkulation im Ozean, ausgelöst durch Unterschiede in Temperatur und Salinität (Salzgehalt) des Wassers. 1) is that part of the ocean circulation which is driven by density differences. Thermohaline circulation is the large-scale circulation of the world's oceans linked to the temperature and salinity of water masses. 2 Begriff und Definition. Thermohaline Circulation. Water is reheated in the Tropics, and then rises to the surface, where it cools, and so on. 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. Die thermohaline Zirkulation, umgangssprachlich auch globales Förderband (englisch ocean conveyor belt), ist ein ozeanographischer Terminus für eine Kombination von Meeresströmungen, die vier der fünf Ozeane miteinander verbinden und sich dabei zu einem Kreislauf globalen Ausmaßes vereinen.. Der Antrieb für diesen umfangreichen Massen- und Wärmeaustausch ist … As opposed to wind-driven currents and tides (which are due to the gravity of moon and sun), the thermohaline circulation (Fig. The cooled salt water plunges to the depths at high latitudes (off the coasts of Norway and Greenland). The upwelling branch of the thermohaline circulation is important A complete cycle can take thousands of years to complete from start to finish, with the cycle contributing a great deal to the mixing of the world's oceans. The thermohaline circulation, often referred to as the ocean's "conveyor belt", links major surface and deep water currents in the Atlantic, Indian, Pacific, and Southern Oceans. Sie können auch eine Definition von Thermohaline Zirkulation selbst hinzufügen. Wind-driven surface currents (such … Thermohaline Zirkulation. Daher sollen nachfolgend im Wesentlichen Funktionsweise, Zusammenhänge, Verortung und Auswirkungen der Thermohalinen Zirkulation untersucht und dargestellt werden.
