Geostrophic turbulence with a magnetic field

Abstract: We propose to study turbulence in the solar tachocline with layered quasi-geostrophic (QG) equations with Lorentz force, as an extension on previous work done on 2D beta-plane MHD turbulence. The equations are derived from the 3D Boussinesq MHD equations. As a preliminary exercise, linear baratropic and baroclinic instabilities are investigated, with a view to study geostrophic turbulence under the influence of a magnetic field analytically as well as numerically.
