Abstract

The causes responsible for changes in the carbon dioxide (CO 2) concentration in the atmosphere were analyzed. A number of uncoupled runs, in which the ocean model was forced by the surface fluxes taken from coupled runs, were carried out for the analysis of the causes. The analysis showed that the increasing heat fluxes in the global change runs were the main reason for the slowdown of the North Atlantic (NA) sinking in the model. It was found that the main reason for a secondary role of moisture fluxes in causing changes in the meridional circulation in the model was their small contribution to the surface buoyancy flux changes.
