Regularization of small scales is considered as an adhoc approach to modeling the effects of unresolved mesoscale eddy activity in the context of geostrophic turbulence. Numerical simulations show that not all such regularizations are equally effective. Analysis of cases where such regularization is effective suggests that the small-scale regularization leads to a change in stability characteristics, allowing for an enhanced inverse cascade of energy (compared to the unregularized case) and thus modifying the larger scales.
