Canuto, V.M., and M.S. Dubovikov, 1997: Physical regimes and dimensional structure of rotating turbulence. Phys. Rev. Lett., 78, 666-669, doi:10.1103/PhysRevLett.78.666.

Numerical simulations of rotating turbulence have given rise to "unexpected results": An increasing Omega did not lead to the "expected" route to a 2D state. A recent model of turbulence leads to a new number N = K / (νΩ) (K and ν are turbulent kinetic energy and viscosity) so that DNS (direct numerical simulation) and LES (large eddy simulation) correspond to N < 1 and N > 1. In the first case, the energy cascade is suppressed, while in the second case there exists an inertial spectrum which is an equilibrium of quasi-2D-3D modes. With these ingredients, we reproduce DNS and LES data.
