Trapping Rossby waves [PDF]

Comptes Rendus. Mathématique, 2009
Waves associated to large scale oceanic motions are gravity waves (Poincaré waves which disperse fast) and quasigeostrophic waves (Rossby waves). In this Note, we show by semiclassical arguments, that Rossby waves can be trapped and we characterize the corresponding initial conditions.

Rossby waves in “shallow water” magnetohydrodynamics [PDF]

Astronomy & Astrophysics, 2007
The influence of a toroidal magnetic field on the dynamics of Rossby waves in a thin layer of ideal conductive fluid on a rotating sphere is studied in the "shallow water" magnetohydrodynamic approximation for the first time. Dispersion relations for magnetic Rossby waves are derived analytically in Cartesian and spherical coordinates. It is shown that

Generation of zonal flows by Rossby waves in the atmosphere [PDF]

Nonlinear Processes in Geophysics, 2004
A novel mechanism for the short-scale Rossby waves interacting with long-scale zonal flows in the Earth's atmosphere is studied. The model is based on the parametric excitation of convective cells by finite amplitude Rossby waves. We use a set of coupled

Rough Topography and Fast Baroclinic Rossby Waves

Geophysical Research Letters
Oceanographic observations have revealed that basin‐scale Rossby waves can travel at speeds systematically exceeding values predicted by linear theory based on the flat‐bottom approximation.

Use of the 3D radon transform to examine the properties of oceanic Rossby waves [PDF]

, 2001
One of the most successful applications of satellite-borne radar altimeter data over the oceans in recent years has been the extraction of information about long-wavelength baroclinic Rossby (or planetary) waves, which play a significant role in ocean ...

Weather conditions and weather forecast on the planets of the solar system based on the behavior of Rossby waves [PDF]

Glasnik Srpskog Geografskog Društva, 2010
Out of all atmospheric processes on the planets of the Solar System, special attention will be devoted here to leading circulation of planetary or global scales, known as Rossby waves.

Generalized (2 + 1)-dimensional mKdV-Burgers equation and its solution by modified hyperbolic function expansion method

Results in Physics, 2019
We investigate a new higher-dimensional nonlinear dynamics model to describe the generation and evolution of Rossby waves. We derive a generalized (2 + 1)-dimensional modified Korteweg-de Vries (mKdV)-Burgers equation by considering the quasi-geostrophic

The vertical structure of oceanic Rossby waves: a comparison of high-resolution model data to theoretical vertical structures [PDF]

, 2011
Tests of the new Rossby wave theories that have been developed over the past decade to account for discrepancies between theoretical wave speeds and those observed by satellite altimeters have focused primarily on the surface signature of such waves.

South Pacific Ocean Dynamics Redistribute Ocean Heat Content and Modulate Heat Exchange With the Atmosphere

Geophysical Research Letters, 2022
The correlation of global ocean surface temperatures with ocean heat content (OHC) at interannual to decadal time scales shows wind‐driven ocean circulation plays a fundamental role in the Earth's energy balance.

Modulation of surface meteorological parameters by extratropical planetary-scale Rossby waves [PDF]

Annales Geophysicae, 2016
This study examines the link between upper-tropospheric planetary-scale Rossby waves and surface meteorological parameters based on the observations made in association with the Ganges Valley Aerosol Experiment (GVAX) campaign at an extratropical site
