摘要：SE INVESTIGA LA ESTRUCTURA DE LA S ONDAS BAROCLÍNICAS EN UNA CORRIENTE ZONAL. USANDO UN MODELO CAUSI-NO-DIVERGENTE DE DOS CAPAS, ES POSIBLE DERIVAR DOS ECUACIONES NO LINEALES QUE DESCRIBEN LOS CAMBIOS CON RESPECTO AL TIEMPO DE LA RAZÓN DE LAS AMPLITUDES Y LA DIFERENCIA DEL ÁNGULO DE FASE ENTRE LA ONDA PROMEDIADA VERTICALMENTE Y LA ONDA TÉRMICA. SE OBTIENEN TODOS LOS ESTADOS ESTACIONARIOS Y SUS PROPIEDADES DE ESTABILIDAD LINEAL.
其他摘要：The structure of baroclinic waves on a zonal current is investigated. Using a two level, quasi-nondivergent model it is possible to derive two nonlinear equations describing the changes in time of the ratio of the amplitudes and the phase angle difference between the vertically averaged wave and the thermal wave. All steady states and their linear stability properties are found. It turns out that one stable steady state describes a westward sloping wave increasing in amplitude with height This state corresponds to the asymptotic state of the amplifying baroclinc wave. Another steady state with the opposite slope is unstable Four additional steady states are found for sufficiently small windshears. They are stable, but of an oscillatory nature and are either vertical or sloping half a wave length.
