Length Scales in a Rotating Stratified Fluid on the Beta Plane
Length Scales Beta Plane Rotating Stratified Fluid
<
2009/4/2
The relationships between vertical and horizontal length scales in a rotating stratified fluid on the beta plane are discussed in an attempt to unify the results of previous papers. The model is stead...
Tidal Oscillations of an Enclosed Rotating Fluid
Enclosed Rotating Fluid Tidal Oscillations
<
2009/4/2
Observations of surface waves in a tilted rotating circular basin of paraboloidal bottom reveal quantitatively the limitations of the predictability of tides by linear inviscid analyses. Through nonli...
A Theory of the Mean Flow Driven by Long Internal Waves in a Rotating Basin, with Application to Lake Kinneret
Mean Flow Driven Rotating Basin Long Internal Waves
<
2009/2/13
The rectified flow induced by wind-driven internal seiches in a rotating lake is studied. Friction and nonlinearity combine to generate a secondary mean flow which is calculated analytically for the c...
An Experimental Study of Gravity-Inertial Waves and Wind-Induced Kelvin-Type Upwellings in a Rotating System
Gravity-Inertial Waves Rotating System Wind-Induced Kelvin-Type Upwellings
<
2009/2/10
Large-amplitude gravity-inertial waves have been observed in stratified seas. These waves, of a shorter period than the Coriolis period, are linked to a gust of wind. Numerous theories have been propo...
A Study of Rotating Baroclinic Nonlinear Flow Around an Island
Rotating Baroclinic Nonlinear Flow perturbation model
<
2009/2/10
Hogg (1972) has developed a perturbation model for the oceanic flow around an island. This perturbation model is restricted to small Rossby numbers. The present study extends Hogg's ideas by consideri...
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 Model for the Seasonal Pycnocline in Rotating Systems with Application to the Baltic Proper
Seasonal Pycnocline Baltic Proper Rotating Systems
<
2009/1/16
A one-dimensional seasonal pycnocline model, primarily intended for use in long-term circulation models, is developed. The model is of the two-layer (integral) type with a turbulent, well mixed surfac...
Wind and Wave Induced Currents in a Rotating Sea with Depth-varying Eddy Viscosity
Wave Induced Currents Rotating Sea Depth-varying Eddy Viscosity
<
2009/1/7
A theory is presented for time-dependent currents induced by a variable wind stress and wave field in deep water away from coastal boundaries. It is based on a second-order perturbation expansion of a...
Rotating Shocks in a Separated Laboratory Channel Flow

<
2009/1/7
Laboratory studies of the effects of wall separation on a hydraulic jump in a rotating channel of rectangular cross section are described. Separation is induced by increasing the rotation rate while m...
Mixing and Intrusions in a Rotating Cold-Core Feature off Cape Blanco, Oregon

2009/1/5
During August 1986, a large cold anomaly was observed in satellite and in situ measurements near Cape Blanco at 42°N, 126°30′W off the Pacific Coast. Detailed vertical profiles of temperature, conduct...
Modeling Rotating Stratified Turbulent Flows with Application to Oceanic Mixed Layers
Stratified Turbulent Flows Oceanic Mixed Layers
<
2009/1/4
Rotational effects on turbulence structure and mixing are investigated using a second-moment closure model. Both explicit and implicit Coriolis terms are considered. A general criterion for rotational...
