  • Ellipsoidal vortices in rotating stratified fluids : beyond the quasi-geostrophic approximation 

    Tsang, Yue-Kin; Dritschel, David G. (2015-01) - Journal article
    We examine the basic properties and stability of isolated vortices having uniform potential vorticity (PV) in a non-hydrostatic rotating stratified fluid, under the Boussinesq approximation. For simplicity, we consider a ...
  • The shape of vortices in quasi-geostrophic turbulence 

    Reinaud, Jean Noel; Dritschel, David Gerard; Koudella, CR (2003-01-10) - Journal article
    The present work discusses the most commonly occurring shape of the coherent vortical structures in rapidly rotating stably stratified turbulence, under the quasi-geostrophic approximation. In decaying turbulence, these ...
