review text: We consider the vorticity-streamfunction formulation. Discretization in time is performed by a second order semi-implicit scheme where the diffusive term is treated in an implicit manner while the convective term is evaluated explicitly. For the discretization of the resulting Stokes- type problem, we introduce a new spectral collocation method. We propose an efficient finite difference preconditioner.
