| Abstract: | In this paper, the relations between the richardson number and the stability of meso and, small-scale perturbations in the atmosphere are discussed by small parameter methods with non-static equilibrium. The criterions of the symmetry instability under the conditions of zero order and first order are
RiF respectively; The criterion of the baroclinic instability
under the condition of zero order is Ri<-8/k2 |
