Two-Point Vorticity Statistics Inverse Turbulent Cascade
2010/12/28
We present a statistical analysis of the two-point vorticity probability density of the vorticity eld generated in the inverse cascade of stationary two-dimensional turbulence.
Point symmetry group of the barotropic vorticity equation
Point symmetry group barotropic vorticity equation
2010/12/1
The complete point symmetry group of the barotropic vorticity equation on the -plane is computed using the direct method supplemented with two different techniques.
Restrictions on the geometry of the periodic vorticity equation
Non-metric Euler equation geodesic flow diffeomor-phism group of the circle

We prove that several evolution equations arising as mathematical models for fluid motion cannot be realized as metric Euler equations on the Lie group Diff1(S1) of all smooth and orientation-preservi...
A spectral scheme is considered for solving the barotropic vorticity equation. The error estimates are proved strictly. The technique used in this paper is also useful for other nonlinear problems def...
