Abstract
It is shown that the improvement in the simulation of eddy activity which results from a decreased grid-length is due primarily to the reduction in effective dissipation rate. This implies that with presently used eddy viscosity formulations, little improvement may be expected to result from higher-order numerical schemes.

Abstract
The comparative study of simplified versions of the equations governing barotropic flow in 1) the f-plane, 2) the β-plane, 3) the spherical surface, leads to a new interpretation of the stabilizing effect of the β-term on the long waves. The relevant observation is that although in the long-wave region the momentum convergence has a large amplitude, its time frequency is also large, so that no significant energy conversion can be performed.
