Hydromagnetic quasi-geostrophic modes in rapidly rotating planetary cores
Elisabeth Canet, Chris Finlay, Alexandre Fournier
The core of a terrestrial-type planet consists of a spherical shell of rapidly rotating, electrically conducting, fluid. Such a body supports two distinct classes of quasi-geostrop…
Forward and adjoint quasi-geostrophic models of the geomagnetic secular variation
Elisabeth Canet, Alexandre Fournier, Dominique Jault
We introduce a quasi-geostrophic model of core dynamics, which aims at describing core processes on geomagnetic secular variation timescales. It extends the formalism of Alfvén tor…
Spherical Couette flow in a dipolar magnetic field
Rainer Hollerbach, Elisabeth Canet, Alexandre Fournier
We consider numerically the flow of an electrically conducting fluid in a differentially rotating spherical shell, in a dipolar magnetic field. For infinitesimal differential rotat…
