    • The critical merger distance between two co-rotating quasi-geostrophic vortices 

      Reinaud, Jean Noel; Dritschel, David Gerard (2005-01-10) - Journal article
      This paper examines the critical merger or strong interaction distance between two equal-potential-vorticity quasi-geostrophic vortices. The interaction between the two vortices depends on five parameters: their volume ...
    • The quasi-geostrophic ellipsoidal vortex model 

      Dritschel, David Gerard; Reinaud, Jean Noel; McKiver, William J (2004-04-25) - Journal article
      We present a simple approximate model for studying general aspects of vortex interactions in a rotating stably-stratified fluid. The model idealizes vortices by ellipsoidal volumes of uniform potential vorticity, a materially ...
