    "abstract": "A thorough analysis of the stability of a coupled version of an\ninter-hemispheric 3-box model of Thermohaline Circulation (THC) is presented.\nThis study follows a similarly structured analysis on an uncoupled version of\nthe same model presented in Part I. We study how the strength of THC changes\nwhen the system undergoes forcings representing global warming conditions. Each\nperturbation to the initial equilibrium is characterized by the total radiative\nforcing realized, by the rate of increase, and by the North-South asymmetry.\nThe choice of suitably defined metrics allows us to determine the boundary\ndividing the set of radiative forcing scenarios that lead the system to\nequilibria characterized by a THC pattern similar to the present one, from\nthose that drive the system to equilibria where the THC is reversed. We also\nconsider different choices for the atmospheric transport parameterizations and\nfor the ratio between the high latitude to tropical radiative forcing. We\ngenerally find that fast forcings are more effective than slow forcings in\ndisrupting the present THC pattern, forcings that are stronger in the northern\nbox are also more effective in destabilizing the system, and that very slow\nforcings do not destabilize the system whatever their asymmetry, unless the\nradiative forcings are very asymmetric and the atmospheric transport is a\nrelatively weak function of the meridional temperature gradient. The changes in\nthe strength of the THC are primarily forced by changes in the latent heat\ntransport in the hemisphere, because of its sensitivity to temperature that\narises from the Clausius-Clapeyron relation.",
