Stability of the Thermohaline Circulation in a Simple Coupled Model
In an analytical study the stability of the thermohaline circulation with respect to freshwater perturbations in high latitudes is investigated. The study is based on a coupled ocean and atmosphere box model in an idealized North Atlantic geometry. The box model provides a qualitative understanding of how the thermohaline circulation is a ected by feedback mechanisms associated with changes in ...
متن کاملVariability of the Thermohaline Circulation in an Ocean General Circulation Model Coupled to an Atmospheric Energy Balance Model
We examine the variability of the ocean’s thermohaline circulation in a Oceanic General Circulation Model (OGCM) coupled to a two dimensional atmospheric Energy Balance Model (EBM). The EBM calculates air temperatures by balancing heat fluxes, including that from the ocean surface; air temperature and ocean circulation evolve together without imposed temperature restrictions except specificatio...
متن کاملAtmospheric Control on the Thermohaline Circulation
In an attempt to elucidate the role of atmospheric and oceanic processes in setting a vigorous ocean overturning circulation in the North Atlantic but not in the North Pacific, a comparison of the observed atmospheric circulation and net surface freshwater fluxes over the North Atlantic and Pacific basins is conducted. It is proposed that the more erratic meridional displacements of the atmosph...
متن کاملGlobal Thermohaline Circulation and Ocean - Atmosphere Coupling
A global ocean general circulation model (GCM) with idealized geometry (two basins of equal size, Marotzke and Willebrand, 1991) is coupled to an energy balance atmospheric model with nonlinear parameterizations of meridional atmospheric transports of heat and moisture. With the coupled model that prescribes the atmospheric heat and moisture transports, the North Atlantic meridional mass overtu...
متن کاملSensitivity of the thermohaline circulation in coupled oceanic GCM – atmospheric EBM experiments
We analyze the sensitivity of the oceanic thermohaline circulation (THC) regarding perturbations in fresh water flux for a range of coupled oceanic general circulation – atmospheric energy balance models. The energy balance model (EBM) predicts surface air temperature and fresh water flux and contains the feedbacks due to meridional transports of sensible and latent heat. In the coupled system ...
