Coupling coefficients and kinetic equation for Rossby waves in multi-layer ocean
Coupling coefficients kinetic equation Rossby waves multi-layer ocean
2009/11/12
The kinetic description of baroclinic Rossby waves in multi-layer model ocean is analysed. Explicit analytical expressions for the coupling coefficients describing energy exchange intensity between di...
The Scattering of Rossby Waves by a Semi-Infinite Barrier
Rossby Waves Semi-Infinite Barrier
2009/4/3
We discuss the scattering of divergent Rossby waves by a semi-infinite vertical barrier of arbitrary orientation on a β plane. The Wiener-Hopf method is used to obtain an integral representation of th...
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...
On the Generation of Baroclinic Rossby Waves in the Ocean by Meteorological Forces
Baroclinic Rossby Waves Meteorological Forces
2009/3/7
The generation of baroclinic Rossby waves in a continuously stratified ocean by fluctuating fields of wind stress, buoyancy flux and atmospheric pressure at the sea surface is studied by means of boun...

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...
Annual Baroclinic Rossby Waves in the Central North Pacific
Annual Baroclinic Rossby Waves Central North Pacific
2009/2/18
We analyze XBT data, collected in the central North Pacific under the NORPAX program (TRANSPAC), by means of inverse methods (cross-spectral fit). We separate the data into two parts: a fluctuation wi...
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...
The Effect of Current Shear on Topographic Rossby Waves
Current Shear Topographic Rossby Waves
2009/2/16
Topographic Rossby waves are long-period waves which occur on continental slopes. In this paper we examine the effect of a mean current on these waves, when the current is directed along the isobaths ...
The Kinetic Energy on a Continental Shelf from Topographic Rossby Waves Generated off the Shelf
Kinetic Energy Topographic Rossby Waves Continental Shelf
2009/2/13
Over a deep barotropic ocean an isolated pressure cell, producing a wind stress curl, generates topographic Rossby waves which are incident on a continental shelf with a simple exponentially varying s...
Topographic Rossby Waves off East Australia：Identification and Role in Shelf Circulation
Topographic Rossby Waves East Australia Shelf Circulation
2009/2/11
Hamon et al.(1975) analyzed two years of surface current data from ships' set along two tracks parallel to 560 km of the east Australian shelf and found a phase lag of 10 days between long (120 day) p...
On Stable and Unstable Rossby Waves in Non-Zonal Oceanic Shear Flow
Rossby Waves Non-Zonal Oceanic Shear Flow
2009/2/7
We derive linear equations for the study of baroclinic instability of a non-zonal oceanic shear flow whose direction is allowed to change with depth. These equations can be used to study unstable dist...

2009/2/7
Bursts of topographic-Rossby-wave energy have been observed in data recorded by an array of current meters moored on the outer continental shelf and slope off Nova Scotia north of the Gulf Stream. The...

2009/2/5
A Kraus-Turner (1967) seasonal mixed-layer model with constant background dissipation is used to study the mixed-layer response to the vertical motions of linear Rossby waves that are not driven by di...
