Two-Dimensional Free Oscillations in Natural Basins
Two-Dimensional Free Oscillations Natural Basins
2009/4/3
A method is designed to calculate normal modes of natural basins. The purpose is to determine the period and configuration of free oscillations in a way that provides for the full two-dimensionality o...
Tracking a Gulf Stream Ring with a Free Drifting Surface Buoy
Gulf Stream Ring Free Drifting Surface Buoy
2009/3/7
A newly developed buoy which is free drifting and tracked by satellite was successfully used to measure the movement of a Gull Stream ring. The buoy, launched in a young ring at 36°15′N, 58°00′W, loop...
Free, Stable Continental Shelf Waves in a Sheared, Barotropic Boundary Current
Stable Continental Shelf Waves Free Barotropic Boundary Current
2009/3/7
The dispersion characteristics of stable, discrete, barotropic, continental shelf wave (CSW) modes propagating in a barotropic boundary current are strongly modified by the dynamical effects of nonuni...
Numerical Computation of Three-Dimensional Circulation in Lake Erie：A Comparison of a Free-Surface Model and a Rigid-Lid Model
Three-Dimensional Circulation Free-Surface Model Lake Erie
2009/2/23
The three-dimensional time-dependent flow in the Western Basin of Lake Erie has been calculated numerically by means of both a two-mode free-surface model and a rigid-lid model. Detailed comparisons o...
Turbulent Free Convection in Fresh and Salt Water：Some Characteristics Revealed by Visualization
Turbulent Free Convection Salt Water Visualization
2009/2/23
Tracers were used to reveal the motions within the boundary layer on water in turbulent free convection. The technique of obtaining a thin sheet of light with an inexpensive laser and a cylindrical le...

Numerical Model Continental Margins Free Topographic Rossby Waves
2009/2/18
Ou (1980, Part 1) presented analytical solutions of free topographic Rossby waves propagating in an infinite wedge filled with a uniformly stratified fluid. We present here in Part 2 a numerical model...
On the Propagation of Free Topographic Rossby Waves near Continental Margins. Part 1：Analytical Model for a Wedge
Free Topographic Rossby Waves Continental Margins Wedge
2009/2/18
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 transfor...
Gulf Stream Trajectories Measured with Free-Drifting Buoys
Gulf Stream Trajectories Free-Drifting Buoys
2009/2/10
During 1975–78, 35 free-drifting buoys measured surface currents in the Gulf Stream region. The buoy trajectories trace numerous paths of the Stream and show that the Stream is strongly influenced by ...
The Free Kelvin Wave with Lateral and Vertical Viscosity
Free Kelvin Wave Lateral Vertical Viscosity
2009/2/6
Free Kelvin wave solutions of the linear shallow-water equations are described, for an f-plane. Lateral and vertical viscous effects are represented by terms ν2u and du, respectively, where (u,v) is t...
The Free Kelvin Wave in Finite-Difference Numerical Models
Free Kelvin Wave Finite-Difference Numerical Models
2009/2/6
The effects of viscosity and finite- differencing on free Kelvin waves in numerical models (which employ the Arakawa B- or C-grid difference schemes) are investigated using the f-plane shallow-water e...
Stability of Free Surface Ekman Layers
Free Surface Ekman Layers wavenumbers α independent parameters
2009/2/5
The stability of free surface, laminar Ekman layers is examined for both the homogeneous and the two-layer case. The eigenvalues of the homogeneous case depend upon the wavenumbers α and &ggr; and the...
Low-Frequency Free Wave and Wind-Driven Motions Over a Submarine Bank
Low-Frequency Free Wave Wind-Driven Motions Submarine Bank
2009/1/21
This study attempts to isolate the physics peculiar to a submarine bank. The particular model is barotropic and contains an infinitely long straight bank within an unbounded ocean basin. The low-frequ...
In applying the Wall layer analogy to a wind blown free surface it is necessary to decide in what coordinate system such an anology is realistic. A smoothed sea surface is taken to be that produced by...
Deep Ocean Response to Hurricanes as Revealed by an Ocean Model with Free Surface. Part I：Axisymmetric Case
Deep Ocean Response Hurricanes Free Surface Axisymmetric Case
2009/1/16
An axisymmetric, hydrostatic ocean model containing a rigid bottom and a free surface is constructed to study the barotropic and baroclinic response in the upper and deep ocean to a wind stress corres...

Free Circulation Quasi-Geostrophic Ocean
2009/1/13
Steady solutions in which quasi-geostrophic potential vorticity is constant along a streamline of the flow are derived for a baroclinic ocean. Friction, transfer by geostrophic eddies, and wind forcin...
