Abstract
The theory of large-scale flows of rotating incompressible fully ionized plasma is developed taking into account the Hall effect in the beta plane approximation for Coriolis force. The Coriolis force is considered for each component of the plasma. In the beta-plane approximation, the Coriolis force is expressed in a local Cartesian coordinate system tied to a fixed point on a sphere, becoming inhomogeneous and thus leading to the beta-effect in both the equation of motion and the electromagnetic field equation. Analysis of linear flows in quasi-two-dimensional approximation has been conducted, demonstrating that in a rotating, fully ionized plasma on a sphere, a new type of flow emerges — the electron Rossby wave, along with hydrodynamic Rossby waves of neutral fluid. The restoring force of such waves is the inhomogeneity of the vertical component of the angular velocity of rotation on the sphere.
