On the multiple-cell thermohaline circulation
The classic Stommel (1961) model of thermohaline circulation has predicted the existence of two modes ofocean motion for the pole-equator system. These are, one-cell thermal and one-cell saline modes. In contrast,the laboratory experiments conducted recently to duplicate this conceptual model have f...

| Resumo: | The classic Stommel (1961) model of thermohaline circulation has predicted the existence of two modes ofocean motion for the pole-equator system. These are, one-cell thermal and one-cell saline modes. In contrast,the laboratory experiments conducted recently to duplicate this conceptual model have found three steadystates in the control space of the model parameters: a two-layer thermal mode, a two-layer saline mode, anda three-layer hybrid state. A two-dimensional theoretical model is applied to investigate the multiple-cellformation. The lowest order solution is analysed using an expansion method and suggesting the aspect ratioas a small parameter. It is shown that asymmetry of vertical distribution between temperature and salinity isresponsible for forming the multiple-cell thermohaline circulation. |
