The omega equation and potential vorticity

WebMathematically, the vorticity of a given velocity field, is defined to be the curl of the velocity field, and is usually denoted with the greek letter omega, where we have used the conventional nabla symbol for the gradient: In component form the vorticity is found by expanding the determinant above, Another important aspect of fluid dynamics ...
