Long term numerical integrations were performed on a two-dimensional model using the barotropic vorticity equation including a space- and time-dependent forcing function and a laminar-type viscosity term. Three different forms of the laminar type viscosity or dissipation term were used. A comparison was made of the effects these different dissipation terms had on the time-dependence of total kinetic energy, and total gradient of vorticity squared, the spectral distribution of kinetic energy, and the stream function field. A difference of behavior of the above variables was found for each form of dissipation.
