Interbasin 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 ...
An Intercomparison of Inverse Methods Using an Eddy-Resolving General Circulation Model
Publisher: American Meteorological Society
Abstract: Three inverse methods (the Bernoulli, beta-spiral, and box inverse methods) are used on mean data from an eddy-resolving oceanic general circulation model, in an attempt to reconstruct the observed mean flow field. Inversions ...
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. ...
Climatology of Cyclogenesis Mechanisms in the Mediterranean
Publisher: American Meteorological Society
Abstract: A general climatology of the main mechanisms involved in Mediterranean cyclogenesis is presented. A diagnostic study of both composite means and case studies is performed to analyze processes occurring in different seasons, ...
Polar Mesoscale Cyclones in the Northeast Atlantic: Comparing Climatologies from ERA-40 and Satellite Imagery
Publisher: American Meteorological Society
Abstract: Polar mesoscale cyclones over the subarctic are thought to be an important component of the coupled atmosphere?ocean climate system. However, the relatively small scale of these features presents some concern as to their ...
Objective Climatology of Cyclones in the Mediterranean Region
Publisher: American Meteorological Society
Abstract: An objective cyclone detection and tracking analysis is performed over an 18-yr period, for the Mediterranean basin. The high-resolution (1.125° ? 1.125° grid) European Centre for Medium-Range Weather Forecasts data used ...
Bimodal Distribution of Tropical Cyclogenesis in the Caribbean: Characteristics and Environmental Factors
Publisher: American Meteorological Society
Abstract: Tropical cyclogenesis critically depends on the presence of warm water at the sea surface. For the North Atlantic basin as a whole, the tropical storm season starts in May, peaks in September, and then declines, generally ...
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 ...
