On statistical zonostrophic instability and the effect of magnetic fields
Chen Wang, Joanne Mason, Andrew D. Gilbert
Zonal flows are mean flows in the east-west direction, which are ubiquitous on planets, and can be formed through 'zonostrophic instability': within turbulence or random waves, a w…
An analytical study of the MHD clamshell instability on a sphere
Chen Wang, Andrew D. Gilbert, Joanne Mason
This paper studies the instability of two-dimensional magnetohydrodynamic (MHD) systems on a sphere using analytical methods. The underlying flow consists of a zonal differential r…
Critical-layer instability of shallow water magnetohydrodynamic shear flows
Chen Wang, Andrew Gilbert, Joanne Mason
In this paper, the instability of shallow water shear flow with a sheared parallel magnetic field is studied. Waves propagating in such magnetic shear flows encounter critical leve…
Nonlinear dynamics of forced baroclinic critical layers
Chen Wang, Neil J. Balmforth
In this paper, we study the forcing of baroclinic critical levels, which arise in stratified fluids with horizontal shear flow along the surfaces where the phase speed of a wave re…
A two-dimensional paradigm for symmetry breaking: the nonlinear Schrodinger equation with a four-well potential
C. Wang, G. Theocharis, P. G. Kevrekidis +4
We study the existence and stability of localized states in the two-dimensional (2D) nonlinear Schrodinger (NLS)/Gross-Pitaevskii equation with a symmetric four-well potential. Usi…
