Analysis of solitary wave solutions of the ZK equation for magnetized Rossby waves under background shear flow

Magnetized Rossby waves are low-frequency planetary waves formed by the coupling of Earth’s rotation and geomagnetic field, and their high-dimensional nonlinear theoretical system remains to be improved. Based on the geomagnetically modified dimensionless Charney equation, combined with multi-scale analysis and perturb...

Dynamical characteristics of a higher dimensional model of magnetized Rossby waves in the ionospheric E-layer and modulational instability analysis

Solitary and breather dynamics of Rossby–Khantadze waves in the ionospheric E-region: a Kadomtsev–Petviashvili study

This study focuses on the weakly ionized E-region of the ionosphere. It systematically investigates (2+1)-dimensional nonlinear Rossby–Khantadze (RK) waves, considering the effects of the Earth’s rotational angular velocity and the latitudinal inhomogeneity of the geomagnetic field. Starting from the potential vorticit...
