Sun, S., and R. Bleck, 2006: Geographic distribution of the diapycnal component of thermohaline circulations in coupled climate models. Ocean Model., 15, 177-199, doi:10.1016/j.ocemod.2006.05.002.
Data archives from four global coupled ocean-atmosphere models are used to construct maps of diapycnal mass ux through selected isopycnal surfaces in the di erent model oceans. The maps illustrate location and strength of the up- and downwelling limbs of thermohaline-forced overturning loops whose stability in the face of rising atmospheric carbon dioxide (CO2) concentrations is of major concern in century-scale climate prediction. The up- and downwelling limbs simulated by the four models for present-day greenhouse gas concentrations are compared with observational estimates, and predicted changes in the overturning brought about by gradually rising atmospheric CO2 content are compared model-to-model. While all models predict some decline in the rate of Atlantic overturning during CO2-induced global warming, the geographic layout of the overturning circulations in each model is found to be remarkably insensitive to the changing climate.
