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 density of sea ...
The adjective thermohaline derives from thermo-referring to temperature and -haline referring to salt content, factors which together determine the density of seawater. The thermohaline circulation is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes.
The Thermohaline Circulation is part of the global ocean circulation. Although this phenomenon is not fully understood yet, it is known that its driving processes are thermohaline forcing and turbulent mixing. [26]
The wind forcing driving this circulation therefore has an outsize influence on the freshwater transport into the Atlantic. [5] Besides, it is thought to control the stability and functioning of the thermohaline circulation. The Tasman Outflow is also directly influenced by wind forcing, especially by winds in the Southern and Pacific Ocean.
Thermohaline Circulation: Density differences drive the thermohaline circulation, also known as the global "conveyor belt," which plays a crucial role in regulating Earth's climate. Cold, dense water formed in the polar regions sinks and moves along the ocean floor toward the equator, while warmer surface waters flow poleward to replace it.
Winds drive ocean currents in the upper 100 meters of the ocean's surface. However, ocean currents also flow thousands of meters below the surface. These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation.
In oceanography, an overflow is a type of deep-water circulation in which denser water flows into an adjacent basin beneath lighter water. This process is significant in thermohaline circulation, contributing to the global ocean's deep water mass formation. [1]
Thermohaline circulation. Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean' and γραφή (graphḗ) 'writing'), also known as oceanology, sea science, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology.
