Abstract

From a two-level nonlinear baroclinic model including frictional dissipation, using Serrin-Joseph's energy method, by means of the variational principle,the nonlinear baroclinic stability criterions of nonzonal flows with the total energy, and total enstrophy, the linear combination of above two quantities respectively are found, and these criterions are compared with the linear stability criterion.
