Thermohaline Ocean Circulation
The thermohaline circulation is that part of the ocean circulation which is driven by fluxes of heat and freshwater across the sea surface and subsequent interior mixing of heat and salt. The term thus refers to a driving mechanism. Important features of the thermohaline circulation are deep water formation, spreading of deep waters partly through deep boundary currents, upwelling and near-surf...
متن کاملShutting Down the Thermohaline Circulation
Past climatic changes were caused by a slowdown of the thermohaline circulation. We use results from experiments with three climate models to show that the expected cooling due to a slowdown of the thermohaline circulation is less in magnitude than the expected warming due to increasing greenhouse gas concentrations. The integrated assessment model FUND and a meta-analysis of climate impacts ar...
متن کاملDestabilization of the thermohaline circulation by transient perturbations to the hydrological cycle
We reconsider the problem of the stability of the thermohaline circulation as described by a two-dimensional Boussinesq model with mixed boundary conditions. We determine how the stability properties of the system depend on the intensity of the hydrological cycle. We define a two-dimensional parameters’ space descriptive of the hydrology of the system and determine, by considering suitable quas...
متن کاملThermohaline Circulation Stability: Study
A thorough analysis of the stability of uncoupled and coupled versions of an interhemispheric 3-box model of Thermohaline Circulation (THC) is presented. The model consists of a northern high latitudes box, a tropical box, and a southern high latitudes box, which respectively can be thought as corresponding to the northern, tropical and southern Atlantic ocean. We study how the strength of THC ...
متن کاملStability of the thermohaline circulation under millennial CO2 forcing and two alternative controls on Atlantic salinity
[1] A large ensemble of experiments with an efficient climate model is carried out to examine stability of the oceanic thermohaline circulation (THC) as a function of two key processes that maintain high Atlantic salinities: the ‘‘Atmospheric Bridge’’ by which moisture is exported from the Atlantic to the Pacific; and ‘‘Agulhas Leakage’’ of salty Indian Ocean waters into the Atlantic. We find t...
