Studying the role of temperature and salinity anomalies in the formation of world ocean meridional circulation modes

A numerical model of the ocean circulation is considered for using in a coupled oceanice-atmosphere climatic model. Preliminary experiments conducted on a numerical grid with a coarse spatial resolution over a period of one thousand years reproduce the World ocean dynamics under climatic surface forcing. By introducing anomalies into the surface sources, the sensitivity of the global ocean circulation to thermohaline variability in the northern regions of the Atlantic Ocean is investigated.
