Breaking Kelvin: Circulation conservation and vortex breakup in MHD at low Magnetic Prandtl Number
D. G. Dritschel, P. H. Diamond, S. M. Tobias
In this paper we examine the role of weak magnetic fields in breaking Kelvin's circulation theorem and in vortex breakup in two-dimensional magnetohydrodynamics for the physically…

Comparison of variational balance models for the rotating shallow water equations
David G. Dritschel, Georg A. Gottwald, Marcel Oliver
We present an extensive numerical comparison of a family of balance models appropriate to the semi-geostrophic limit of the rotating shallow water equations, and derived by variati…
