    review text
    The stability analysis of some commonly used numerical procedures for a finite difference linear barotropic vorticity equation is performed. Upper bounds of the time step to be used are given to maintain stable the numerical processes. In some special cases it is verified that these iterative procedures are block successive relaxation methods. The optimum process is an underrelaxation process. Numerical calculations support the analytical results.
