Nonlinear Rossby waves in zonally varying flow under generalized beta approximation

Dynamics of Atmospheres and Oceans, 2019
We investigate the dynamics of nonlinear Rossby waves in zonally varying background jet flow under generalized beta approximation. Potential forcing, topography and dissipation are all included as influential physical factors. We derive a new modified (2

A new model equation for nonlinear Rossby waves and some of its solutions

Physics Letters, Section A: General, Atomic and Solid State Physics, 2019
In this paper, we investigate the ( 2 + 1 ) dimensional nonlinear Rossby waves under non-traditional approximation. Using the asymptotic methods of multiple scales and weak nonlinear perturbation expansions, we derive a new modified Zakharov–Kuznetsov ...

Rossby waves with the change of β

Applied Mathematics and Mechanics (English Edition), 1992
The variation of the Rossby parameter \(\beta\) with latitude is considered, and the parameter \(\gamma=-{d\beta\over dy}\) is introduced. It is seen that the effect of \(\gamma\) is remarkable in the high latitude regions.

Nonlinear wave propagation on a sphere: Interaction between Rossby waves and gravity waves; stability of the Rossby waves

Geophysical and Astrophysical Fluid Dynamics, 1994
Abstract An analytical spectral model of the barotropic divergent equations on a sphere is developed using the potential-stream function formulation and the normal modes as basic functions. Explicit expressions of the coefficients of nonlinear interaction are obtained in the asymptotic case of a slowly rotating sphere, i.e. when the normal modes can be
