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 ...
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 ...
