Thermohaline circulation is also called overturning circulation. It is driven by density. The time scale for thermohaine is 1000 years.

"Thermo" in "thermohaline" refers to heat or temperature. "Thermohaline" describes ocean currents driven by differences in temperature and salinity.
The thermohaline circulation is a term for the global density-driven circulation of the oceans. Derivation is from thermo- for heat and -haline for salt, which together determine the density of sea water
The term thermohaline circulation ( THC ) refers to the part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes
Another name for thermohaline current is "conveyor belt," which some call this current of the ocean.

thermohaline circulation
Another name for thermohaline circulation is the ocean conveyor belt. This circulation pattern involves the movement of water around the world's oceans based on differences in temperature and salinity.
The two characteristics of water that combine to form a thermohaline current are temperature and salinity. As water becomes cold and more saline, it becomes denser and sinks to the ocean floor, driving the vertical circulation of the ocean known as the thermohaline circulation.
It is gravity that drives thermohaline circulation. It's a gravity current. We usually apply the term thermohaline circulation to the deep ocean currents that are driven by gravity. Colder water or water that has a higher salt content than other water is more dense, and gravity will act on it to pull it "down" deeper. It will displace warmer or less salty water and move to greater depths. This sets the stage for a deep ocean current we call a thermohaline expressway. Use the links below for more information on gravity currents (which are sometimes called density currents)._______________________sflo:I would say this answer is limited in explaining what drives thermohaline circulation. Changes in density certainly affect circulation, particularly when water emerges from the deep or submerges to depths (upwelling and downwelling), but the effects of "gravity" on water masses of varying densities aren't a driver of circulation, per se. I would like to point that within the "thermohaline circulation," "thermo-" and "haline" are both components of the name. Thus in a more elemental manner, it makes more sense to explain this phenomenon by temperature and salinity differences, as well as the resulting changes in density, rather than merely "gravity."For a great snap-shot of our current understanding (or rather lack-therof) of the thermohaline circulation, what drives it, and how it affects or is affected by climate, please look-up:"Thermohaline circulation: The current climate" Nature421, 699 (13 February 2003) | doi:10.1038/421699a == ==
Yes, the thermohaline currents will be affected.
The mathematical term for "mean" is "mean".The popular, or colloquial term for "mean" is "average".
