The Role of Variable Coriolis Parameter in the Propagation of Inertia-Gravity Waves During the Process of Geostrophic Adjustment
Variable Coriolis Parameter Geostrophic Adjustment Inertia-Gravity Waves
2009/4/3
This analysis treats the transient inertia-gravity wave response of a shallow fluid to an impulsive addition of momentum. The Coriolis parameter varies with latitude, but Rossby waves are not consider...
On Geostrophic Adjustment in Sea Straits and Wide Estuaries：Theory and Laboratory Experiments. Part II—Two-Layer System
Sea Straits II—Two-Layer System Wide Estuaries
2009/2/23
A frictionless nonlinear model with allowance for motions which are far from a state of geostrophic balance is considered in order to describe the dynamics of outflows consisting of two layers of flui...
On Geostrophic Adjustment in Sea Straits and Wide Estuaries：Theory and Laboratory Experiments. Part I：One-Layer System
Sea Straits Wide Estuaries One-Layer System
2009/2/23
The dynamics of outflows from sea straits and wide estuaries are examined through a simplified frictionless model whose primary motions are not constrained to be quasi-geostrophic. The potential vorti...
Some Two-Layer Models of the Shelf-Slope Front：Geostrophic Adjustment and its Maintenance
Shelf-Slope Front two-layered frontal system Geostrophic Adjustment
2009/2/6
Two conceptual models of a two-layered frontal system are presented to study the wintertime shelf-slope front. The first model examines the geostrophic adjustment over a step topography after the fall...
Geostrophic Adjustment：A Mechanism for Frontogenesis
Frontogenesis two-dimensional model motionless fluid
2009/1/20
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 ...
The Rossby Adjustment Problem in a Rotating, Stratified Channel, with and without Topography
general circulation model Stratified Channel Topography
2009/1/19
Some numerical experiments On geostrophic adjustment in a gratified channel were carried out, partly to test the use of an ocean general circulation model (GCM), and partly to elucidate the dynamical ...
A Geostrophic Adjustment Model of a Tidal Mixing Front
Geostrophic Adjustment Model Tidal Mixing Front
2009/1/16
This paper presents a model of a tidal mixing front as occurring between well mixed and (seasonally) stratified water in tidally energetic areas in continental shelf seas. The model examines the geost...
Adjustment of the Ocean under Buoyancy Forces. Part I：The Role of Kelvin Waves
Buoyancy Forces Kelvin Waves
2009/1/13
The early stages of the adjustment of an ocean toward equilibrium is examined using an ocean general circulation model. The initial state is one with uniform meridional potential temperature gradients...
The potential and kinetic energy spectra following geostrophic adjustment of a barotropic fluid are determined as functions of the spectrum of arbitrary initial sea level or velocity. Remarkably, the ...
The problem of geostrophic adjustment, originally considered by C.G. Rossby, is solved in an axisymmetric geometry for a continuously stratified fluid, where the adjusted final state is in hydrostatic...
Ideal-Fluid Thermocline with Weakly Convective Adjustment in a Subpolar Basin
Fluid Thermocline Convective Adjustment Subpolar Basin
2009/1/5
The ideal-fluid thermocline with continuous stratification is extended to include a weakly convective adjustment process taking place in a subpolar basin. The convective adjustment creates a well-mixe...
Aspects of Geostrophic Adjustment during Tropical Ocean Data Assimilation
Tropical Ocean Data Assimilation Geostrophic Adjustment
2008/12/30
Subsurface temperature data from the ship-of-opportunity network in the tropical Pacific Ocean was assimilated into a simple reduced-gravity model. A large initialization shock was found to occur in t...
A geostrophic adjustment model is used to find out how water can cross the equator, and how far it can reach, while conserving its potential vorticity, in the context of geostrophic adjustment. A seri...

2008/12/17
The Trade Adjustment Assistance (TAA) program for workers, from
its inception in 1962 to its restructuring in 1981, offers an interesting
case of government failure. Intended to provide workers with...
Energetics of Gravitational Adjustment for Mesoscale Chimneys
Gravitational Adjustment Mesoscale Chimneys energy flux
2008/12/17
The rates of energy flux out of newly formed circular patches of dense water (chimneys) are considered as a function of patch size on an f plane. The dense fluid resulting from a rapid deep convective...
