Circulation and Exchange in Choked Marginal Seas
Publisher: American Meteorological Society
Abstract: A theory for the exchange between a rotating, buoyancy-forced marginal sea and an ocean is developed and tested numerically. Cooling over the marginal sea leads to sinking and sets up a two-layer exchange flow, with a warm ...
On the Crossover of Boundary Currents in an Idealized Model of the Red Sea
Publisher: American Meteorological Society
Abstract: he west-to-east crossover of boundary currents has been seen in mean circulation schemes from several past models of the Red Sea. This study investigates the mechanisms that produce and control the crossover in an idealized, ...
A Porous-Medium Theory for Barotropic Flow through Ridges and Archipelagos
Publisher: American Meteorological Society
Abstract: A linear theory for the treatment of complex ridges and archipelagos as porous media is presented. The theory assumes a barotropic, wind-driven ocean with uniform depth. A porous ridge is formed by shrinking the meridional ...
The Interaction of an Eddy with an Unstable Jet
Publisher: American Meteorological Society
Abstract: Interactions between an unstable jet and eddy are explored using a jet with piecewise constant potential vorticity. A linear theory is developed for the case where the jet is nearly zonal and the eddy is far away in the ...
A Laboratory Model of Exchange and Mixing between Western Boundary Layers and Subbasin Recirculation Gyres
Publisher: American Meteorological Society
Abstract: Chaotic advection is suggested as a possible mechanism for fluid exchange and mixing among a western boundary current and subbasin recirculation gyres. Applications include the North Atlantic Deep Western Boundary Current ...
Continuous Dynamical Modes in Straits Having Arbitrary Cross Sections, with Applications to the Bab al Mandab
Publisher: American Meteorological Society
Abstract: The continuous dynamical modes of the exchange flow in the Bab al Mandab are computed in an attempt to assess the hydraulic character of the flow at the sill. First, an extended version of the Taylor?Goldstein equation for ...
The Western Alboran Gyre: an analysis of its properties and its exchange with surrounding water
Publisher: American Meteorological Society
Abstract: One of the largest and most persistent features in the Alboran Sea is the Western Alboran Gyre (WAG), an anticyclonic recirculation bounded by the Atlantic Jet (AJ) to the north and the Moroccan coast to the south. Eulerian ...
The Influence of an Eddy in the Success Rates and Distributions of Passively Advected or Actively Swimming Biological Organisms Crossing the Continental Slope
Publisher: American Meteorological Society
Abstract: The Lagrangian characteristics of the surface flow field arising when an idealized, anticyclonic, mesoscale, isolated deep-ocean eddy collides with continental slope and shelf topography are explored. In addition to fluid ...
Transport and Dynamics of the Panay Sill Overflow in the Philippine Seas
Publisher: American Meteorological Society
Abstract: Observations of stratification and currents between June 2007 and March 2009 reveal a strong overflow between 400- and 570-m depth from the Panay Strait into the Sulu Sea. The overflow water is derived from approximately ...
Pacific Abyssal Transport and Mixing: Through the Samoan Passage versus around the Manihiki Plateau
Publisher: American Meteorological Society
Abstract: AbstractThe main source feeding the abyssal circulation of the North Pacific is the deep, northward flow of 5?6 Sverdrups (Sv; 1 Sv ≡ 106 m3 s?1) through the Samoan Passage. A recent field campaign has shown that this flow ...
