A comparison of the performance of 4D-Var in an explicit and implicit version of a nonlinear barotropic ocean model
4D-Var explicit and implicit version nonlinear barotropic ocean model
2009/11/3
A comparison is made of the performance of the four-dimensional variational data assimilation (4D-Var) method in an explicit and implicit version of a barotropic quasi-geostrophic model of the wind-dr...
Water motion in the barotropic mode, directly forced by suddenly imposed wind stress, is investigated in basins with arbitrary topography, but paying special attention to long basins, in which the dep...
We study below with the aid of linearized equations, but using a quadratic bottom friction law, the barotropic forced (aperiodic) response to wind stress or external pressure gradient of various simpl...
Barotropic Rossby Waves in a Zonal Current：Effects of Lateral Viscosity
Barotropic Rossby Waves Zonal Current Lateral Viscosity
2009/3/24
The behavior of a barotropic Rossby wave in a zonal current is studied theoretically using a beta-plane ocean of constant depth in which the current depends only on latitude. The wave may be reflected...
The Transmission and Decay of Barotropic Topographic Rossby Waves Incident on a Continental Shelf
Barotropic Topographic Rossby Waves Continental Shelf
2009/3/7
We know that long-period (>1 day) and long-wavelength (>100 km) topographical Rossby waves can be generated by a wind acting directly on a continental shelf (Adams and Buchwald, 1969). Here we examine...
An experimental method for producing an isolated eddy in a laboratory tank is described, along with the simple viscous theory of the behavior of the eddy in an ordinary cylindrical tank without the β-...
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...
A Hindcast of Barotropic Response over the Oregon-Washington Continental Shelf during the Summer of 1972
Barotropic Response Summer Oregon-Washington Continental Shelf
2009/2/23
Hindeasts of bottom currents on the southern Washington continental shelf are made on the basis of a long-wave approximation to the vorticity equation for a barotropic flow. Resistance of the shelf bo...
A Spectral Theory of Nonlinear Barotropic Motion above Irregular Topography
Nonlinear Barotropic Motion Irregular Topography
2009/2/23
If a field of randomly distributed barotropic eddies interacts with underlying topographic features in a rotating reference frame, the flow is observed to develop, after a time the order of an eddy tu...
Normal Modes of the World Ocean. Part I. Design of a Finite-Element Barotropic Model
Normal Modes World Ocean Finite-Element Barotropic Model
2009/2/23
The linearized primitive equations for a barotropic world ocean are discretized by means of first-order, piecewise-linear finite elements. Surface elevation and Stokes/Helmholtz velocity potentials ar...
Dynamical Forecast Experiments with a Barotropic Open Ocean Model
Dynamical Forecast Experiments Barotropic Open Ocean Model
2009/2/19
The initial/boundary value problem for the barotropic version of a quasi-geostrophic open ocean model which requires normal flow everywhere on the boundary and vorticity on the inflow is studied. Para...
On the Stability of a Fluid with Specialized Density Stratification. Part II：Mixed Baroclinic-Barotropic Instability with Application to the Northeast Pacific
Density Stratification Mixed Baroclinic-Barotropic Instability Northeast Pacific
2009/2/18
Low-frequency motions (0.25 cpd) have recently been observed in Juan de Fuca Strait. The three-layer model developed in Part I of this paper is used to show that some of this activity may be due to an...
Propagation of Barotropic Continental Shelf Waves over Irregular Bottom Topography
Barotropic Continental Shelf Waves Irregular Bottom Topography
2009/2/16
Using a geometry which roughly approximates that of a typical continental shelf and slope, the effects of a random bottom topography on free barotropic shelf waves are found. The bathymetric irregular...

2009/2/13
A finite-difference scheme is used in order to study the generation and propagation of long barotropic waves and storm surges along the western coast of Norway. The performance of the numerical scheme...

2009/2/13
During the Coastal Upwelling Experiment of 1973, several current meter moorings were deployed on the Oregon continental shelf and slope. Data from 16 current meters and temperature sensors which were ...
