How the ratio of meridional flux of fresh-water to flux of heat fixes the latitude where low salinity intermediate water sinks

Prescription of the meridional fluxes of fresh-water and heat fixes lower limits on the magnitude of meridional volume fluxes, the direction and relative depths at which they occur, and the latitude at which low salinity intermediate water converges and sinks. It also reveals that the main transport occurs in two separate meridional cells with opposing sense of rotation, and determines the latitude of the boundary between them.
