3-D Calculations Showing the Effects of Stratification on the Evolution of Trailing Vortices

We have computed numerical solutions to the 3-D Navier-Stokes equations for a stratified, incompressible fluid. Our results show that stratification significantly modifies the phenomena that occur during the vertical migration and linking instability of trailing vortices. In particular we show that stratification accelerates the development of the linking instability and suppresses the vertical migration of the trailing vortices.
