WebIntroduction. Gottwald derived the nonlinear dispersive Zakharov–Kuznetsov equation from the quasigeostrophic barotropic vorticity equation [1], where weakly nonlinear and long wave multiple scale analysis were applied to two dimensions and derived the Zakharov–Kuznetsov (ZK for short) equation for nonlinear Rossby waves. WebThe Rossby mode can lead to the outflow of angular momentum and the decretion of gas from a spinning planet. The Rossby mode provides a negative feedback that regulates the planetary spin and mass. We compare the growth rate of the two modes as a function of the width of BL, the Mach number, and the spin rate of planets.
