RISInterbasin Exchange of Bottom Water in Ocean General Circulation Models
Publisher: American Meteorological Society
Abstract: The abyssal part of the thermohaline circulation can pass through narrow channels between ocean basins, which can potentially be resolved by high-resolution ocean models such as the Fine Resolution Antarctic Model. However, ...
Abyssal Channel Flow in Ocean General Circulation Models with Application to the Vema Channel
Publisher: American Meteorological Society
Abstract: An idealized Cox model is shown to pass a flux given by g?H2/2f though a deep channel, single grid-box wide, consistent with analytical models. This flux can, however, be significantly increased or decreased by the presence ...
Are “Great Salinity Anomalies” Advective?
Publisher: American Meteorological Society
Abstract: ?Great Salinity Anomalies? (GSAs) have been observed to propagate around the North Atlantic subpolar gyre. Similar anomalies occur in the Third Hadley Centre Coupled Atmosphere?Ocean GCM (HadCM3) of preindustrial climate. ...
Global Ocean Circulation Modes Derived from a Multiple Box Model
Publisher: American Meteorological Society
Abstract: A 16-box model of the global ocean circulation is constructed to investigate the sensitivity of the thermohaline circulation to upper-ocean density perturbations. The model attempts to represent the main geographical ...
Sensitivity of the North Atlantic to Surface Forcing in an Ocean General Circulation Model
Publisher: American Meteorological Society
Abstract: The sensitivity of the circulation and surface properties of the North Atlantic to different forms of surface forcing is investigated using a Bryan and Cox type model. Forcing taking the form of heat and freshwater fluxes ...
