CIRCULATION IN THE ROSS SEA SECTOR OF THE SOUTHERN OCEAN: REPRESENTATION IN NUMERICAL MODELS
Abstract: The circulation in the Ross Sea sector of the Southern Ocean is examined in three ... numberical models of intermediate to high resolution. Despite the model differences (including physics ... , forcing) the circulation representation is relatively consistent, both in terms of the mean and some ... aspects of monthly variability. This could point to strong bathymetric constraints on the circulation. In ...
