Abstract : A simple, two-layer numerical model of the upper tropical ocean has been added to a pre-existing primitive equation model of a zonally-symmetric tropical atmosphere in order to predict a meridional profile of sea-surface temperature and its relationship to the atmospheric intertropical convergence zone (ITCZ). With an initially flat temperature profile near the equator, it is found that a cold equatorial surface progressively develops on account of upwelling and vertical mixing in the sea. A single ITCZ establishes itself at first over the equator, but then migrates poleward as the equator cools; the convergence zone remains single despite the eventual double surface temperature maximum. This marked hemispheric asymmetry is in accord with satellite observations. (Author)
