On the Separation of the Brazil Current from the Coast
Publisher: American Meteorological Society
Abstract: A series of numerical experiments, using analytical and numerical models, leads to the conclusion that the separation of the Brazil Current from the coast can be related to the northward momentum of the Malvinas Current. ...
A Numerical Study of the Agulhas Retroflection: The Role of Bottom Topography
Publisher: American Meteorological Society
Abstract: The oceanic circulation near the eastern margin of the African continent is dominated by the poleward flow of the Agulhas Current. The Agulhas Current separates from the African coast near the southern tip of the continent, ...
The Low-Frequency Variability of the Southern Ocean Circulation
Publisher: American Meteorological Society
Abstract: ong time series of sea surface height (SSH), sea surface temperature, and wind stress curl are used to determine the main modes of low-frequency variability of the Southern Ocean (SO) circulation. The dominant mode is a ...
On the Upwelling of Downwelling Currents
Publisher: American Meteorological Society
Abstract: The term ?downwelling currents? refers to currents with a downslope mass flux in the bottom boundary layer. Examples are the Malvinas and Southland Currents in the Southern Hemisphere and the Oyashio in the Northern ...
The Impact of Boundary Conditions on the Upstream Spreading of Bottom-Trapped Plumes
Publisher: American Meteorological Society
Abstract: his study shows that simulations of bottom-trapped plumes in periodic or closed domains generate a spurious cyclonic current that arrests the natural tendency of the plume to move upstream. Furthermore, it also shows that ...
On the Decay of the Meanders of Eastward Currents
Publisher: American Meteorological Society
Abstract: The separation of western boundary currents from the coast and their eastward extensions into the open ocean are characterized by the presence of quasi-stationary, large-scale meanders. These meanders result when the western ...
The Upstream Spreading of Bottom-Trapped Plumes
Publisher: American Meteorological Society
Abstract: It is well known that numerical simulations of freshwater discharges produce plumes that spread in the direction opposite to that of the propagation of coastally trapped waves (the upstream direction). The lack of a theory ...
The Spindown of Bottom-Trapped Plumes
Publisher: American Meteorological Society
Abstract: This note considers the decay of a bottom-trapped freshwater plume after the causative freshwater inflow has ceased. It is shown that shortly after the low-density inflow stops, the barotropic pressure field that it created ...
Geostrophic Velocity Measurement Techniques for the Meridional Overturning Circulation and Meridional Heat Transport in the South Atlantic
Publisher: American Meteorological Society
Abstract: wo ocean general circulation models are used to test the ability of geostrophic velocity measurement systems to observe the meridional overturning circulation (MOC) and meridional heat transport (MHT) in the South Atlantic. ...
