Some Effects of a Seamount on Oceanic Flows
Publisher: American Meteorological Society
Abstract: To demonstrate some effects of a seamount an oceanic flows, we have considered a uniform, two-layer flow passing a right circular cylinder of arbitrary height in a rotating fluid. In the case of vanishing stratification, ...
Flow near a Continental Boundary Driven by an Oceanic Jet
Publisher: American Meteorological Society
Abstract: To provide possible dynamical interpretations of the GulfStream-induced circulation in the Middle Atlantic Bight (MAB), the inshore flow driven by a steady and straight jet in a homogeneous ocean is considered via similarity ...
On the Propagation of Free Topographic Rossby Waves near Continental Margins. Part 1: Analytical Model for a Wedge
Publisher: American Meteorological Society
Abstract: An analytical model has been constructed to study the propagation of free waves of subinertial frequency in an infinite wedge filled with a uniformly stratified fluid. The problem is found to transform into the corresponding ...
A Model of Buoyant Throughflow: With Application to Branching of the Tsushima Current
Publisher: American Meteorological Society
Abstract: A reduced-gravity model is used here to investigate the dynamics of a buoyant flow through a strait driven by pressure difference of the adjoining basins. Assuming the flow to be hydraulically controlled so that the transport ...
On the Energy Conversion during Geostrophic Adjustment
Publisher: American Meteorological Society
Abstract: It is found that for a continuously stratified fluid which remains so during the geostrophic adjustment, the energy conversion ratio ? (≡?KE/?PE) is ½, in contrast to the value of ? for a two-layer fluid. Since the two-layer ...
A Time-Dependent Model of a Coastal Polynya
Publisher: American Meteorological Society
Abstract: An idealized model is used here to examine the temporal behavior of a coastal polynya driven by an offshore wind. The model has incorporated the important effect of a finite surface dift by which the frazil ice formed in ...
Termination of an Equatorial Jet in a Gulf
Publisher: American Meteorological Society
Abstract: Motivated by the observed branching of the Equatorial Undercurrent in the Gulf of Guinea, an idealized model is developed here to examine the termination of an equatorial jet in a gulf. Similarity solutions are, found that ...
Wind-Driven Motion near a Shelf-Slope Front
Publisher: American Meteorological Society
Abstract: A two-dimensional, two-layered frontal system is used to examine the wind-driven motion near a shelf-slope front. In the linear regime, the along-frontal current is characterized by barotropic perturbations. The front is ...
Geostrophic Adjustment: A Mechanism for Frontogenesis
Publisher: American Meteorological Society
Abstract: A simple two-dimensional model is used to determine the geostrophically adjusted state of an initially motionless fluid with lateral density gradient. It is an extension of the much studied two-layer models to the case ...
A Model of Tidal Rectification by Potential Vorticity Mixing. Part II: Frontal Regime
Publisher: American Meteorological Society
Abstract: A model of tidal rectification in a homogeneous ocean (Part I) is extended here to include a front that separates shelf and slope waters. The front is approximated as a density discontinuity, the stratification and anchoring ...
