Study of the Large Scale Circulation and Water Mass Formation in the Nordic Seasand Arctic Ocean

摘要

In this thesis, production of dense water that feeds the dense overflows acrossthe Greenland-Scotland Ridge has been considered. A new circulation scheme is developed which is consistent with the water masses, currents and air-sea fluxes in the region, and with the important observation that the dense overflows show little or no seasonal or interannual variability. An inverse box model has been constructed that shows that the new circulation scheme is consistent with conservation statements for mass, heat and salt as well. (MM).
