Frontogenesis in an Advective Mixed-Layer Model
Publisher: American Meteorological Society
Abstract: Through an analysis of a multi-dimensional extension of the bulk mixed layer model of Kraus and Turner (1967) it is shown how, even under spatially uniform atmospheric conditions, an initially smooth horizontal temperature ...
Effects of Velocity Shear in Advective Mixed-Layer Models
Publisher: American Meteorological Society
Abstract: A general multidimensional model of the upper mixed layer of oceans and lakes is presented. The density profile is approximated as uniform over the depth of the layer. Such an assumption is not made for the distribution ...
Inertially Induced Connections between Subgyres in the South Indian Ocean
Publisher: American Meteorological Society
Abstract: A barotropic shallow-water model and continuation techniques are used to investigate steady solutions in an idealized South Indian Ocean basin containing Madagascar. The aim is to study the role of inertia in a possible ...
On the Steadiness of Separating Meandering Currents
Publisher: American Meteorological Society
Abstract: The existence of inertial steady currents that separate from a coast and meander afterward is investigated. By integrating the zonal momentum equation over a suitable area, it is shown that retroflecting currents cannot ...
Reply to “Comments on ‘On the Steadiness of Separating Meandering Currents’”
Publisher: American Meteorological Society
Abstract: he authors thank Nof et al. for their comments on the authors? paper ?On the steadiness of separating meandering currents.? The authors? paper was motivated by a series of papers by Nof et al. Under a certain set of ...
Separation of an Inertial Boundary Current from a Curved Coastline
Publisher: American Meteorological Society
Abstract: A two-layer model is used to examine the separation of an inertial boundary current from a curved coastline and its subsequent path as a free jet. To isolate the inertial effect, the boundary current is confined to the ...
Stability of the Atlantic Overturning Circulation: Competition between Bering Strait Freshwater Flux and Agulhas Heat and Salt Sources
Publisher: American Meteorological Society
Abstract: The role played by interocean fluxes of buoyancy in stabilizing the present-day overturning circulation of the Atlantic Ocean is examined. A 2D model of the Atlantic overturning circulation is used, in which the interocean ...
On the Physics of the Agulhas Current: Steady Retroflection Regimes
Publisher: American Meteorological Society
Abstract: From previous model studies, it has become clear that several physical mechanisms may be at work in the retroflection of the Agulhas Current. Here, a systematic study of steady barotropic flows connecting the Indian Ocean ...
The Influence of the Indian Ocean on ENSO Stability and Flavor
Publisher: American Meteorological Society
Abstract: he effect of long-term trends and interannual, ENSO-driven variability in the Indian Ocean (IO) on the stability and spatial pattern of ENSO is investigated with an intermediate-complexity two-basin model. The Pacific basin ...
A New Regime of the Agulhas Current Retroflection: Turbulent Choking of Indian–Atlantic leakage
Publisher: American Meteorological Society
Abstract: n analysis of the Indian Ocean circulation and the Agulhas Current retroflection is carried out using a primitive equation model with simplified coastline and flat bottom. Four configurations with 0.25° and 0.1° horizontal ...
