Descripción: The investigation explores the possibility that the observed intermonthly variations in the atmosphere may be described by a nonlinear low-order model containing nine components. The model is formulated on a f-plane and contains only wave-wave interactions. It is based on the equivalent barotropic atmosphere formulated in such a way that it contains both heating and dissipations. The wave numbers vary from 1 to 3 in the zonal and the meridional direction. Most of the integrations of the model assume that the oscillations are a planetary phenomenon, and they have therefore been performed with a maximum wavelength of 28000 km. The results show that the observed periods (30-35, 45 and 70 days) may be reproduced by the model. Other periods are also found, but they are mainly of small amplitudes. The model permits a determination of the heating pattern necessary to produce the observed oscillations. It is required that the heating level is above the time-averaged heating in the atmosphere, and the heating is such that it displays a strong meridional heating gradient. The investigation is a continuation of an earlier attempt to model intermonthly oscillations using a very simple three-component model based on the first equation of motion with non-linear advection and momentum forcing and dissipation. The new model permits a more physical description of the phenomena.
EL TRABAJO EXPLORA LA POSIBILIDAD DE QUE LAS VARIACIONES INTERMENSUALES OBSERVADAS EN LA ATMÓSFERA PEDAN SER DESCRITAS POR UN MODELO NO LINEAL, DE BAJO ORDEN, CONTENIENDO NUEVE COMPONENTES. EL MODELO ES FORMULADO SOBRE UN PLANO-F Y CONTIENE SOLAMENTE INTERACCIONES DE ONDA CON ONDA. ESTA BASADO EN LA ATMÓSFERA BAROTRÓPICA EQUIVALENTE FORMULADA DE TAL MANERA QUE CONTIENE TANTO CALENTAMIENTO COMO DISIPACIONES. LOS NÚMEROS DE ONDA VARÍAN DE 1 A 3 EN AMBAS DIRECCIONES ZONAL Y MERIDIONAL. LA MAYORÍA DE LAS INTEGRACIONES DEL MODELO SUPONEN QUE LAS OSCILACIONES SON UN FENÓMENO PLANETARIO Y, POR CONSIGUIENTE, HAN SIDO FORMULADAS CON UNA MÁXIMA LONGITUD DE ONDA DE 28000 KM.
