  We introduce a new regularization of the rotational Navier-Stokes equations
that we call the Rotational Approximate Deconvolution Model (RADM). We
generalize the deconvolution type model, studied by Berselli and Lewandowski
[5], to the RADM model with fractional regularization where the convergence of
the solution is studied with weaker conditions on the parameter regularization.
