Trapping Rossby waves [PDF]

open access: yesComptes 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]

open access: yesAstronomy & 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

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

open access: yes, 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 ...

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

open access: yes, 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

open access: yesGeophysical 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.

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

open access: yesResults 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

Modulational instability of Rossby and drift waves and generation of zonal jets [PDF]

open access: yes, 2010
We study the modulational instability of geophysical Rossby and plasma drill waves within the Charney-Hasegawa-Mima (CH M) model both theoretically, using truncated (four-mode and three-mode) models, and numerically, using direct simulations of CHM ...

Oceanic planetary waves in the coupled ocean-atmosphere system [PDF]

open access: yes, 2005
The propagation of planetary, or Rossby, waves is studied under the effects of different atmospheric couplings. First, analytical matchings are formulated in which a Rossby wave is coupled to different thermodynamical atmospheres, from a simple heat flux

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

open access: yesAnnales 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

Topographic solitary waves and groups

open access: yesOcean and Coastal Research, 2022
We examine nonlinear topographic waves in barotropic, rigid lid models with a focus on how depth shapes can or cannot support solitary waves. Comparisons between the full equations and the quasigeostrophic system show that the conditions for vanishing ...
