Abstract

We study two-dimensional incompressible turbulence on the β plane and propose a modification to the Rhines scale that takes into account the bottom friction. The modified Rhines scale is studied numerically, and found to predict accurately the jet number and the energy peak of the β-plane turbulence for strong β. The intermediate cases show a transition from the (isotropic) friction scale to the Rhines one, as the proper halting scale for the inverse cascade. © 2002 The American Physical Society.
