On the conditions of internal tide wave generation along the west coast of Mexico

Baines’ (1982) model was used to calculate the energy flux of the barotropic M2 waves to internal waves. An estimation of their amplitudes in a section where the continental shelf declines was calculated. Fluxes and amplitudes of the internal waves are shown to be not only dependent on the barotropi...

An estimation of their amplitudes in a section where the continental shelf declines was calculated. Fluxes and amplitudes of the internal waves are shown to be not only dependent on the barotropic tide intensity but also on its arrival angle to the shelf, which changes greatly. By using the vertical distribution of the Brunt-Väisälä frequency in the region of study, the trajectories of the energy flux (y) of the internal waves were calculated. By using bathymetric maps, the inclination of the shelf relief (α) was obtained. Our results show that α/y ≈ l is true for most of the sections in the continental slope, indicating optimum conditions for the generation of internal tides close to the Mexican Pacitic coast. According to the linear model of internal waves, an estimation of the parameters of the semidiurnal internal tides close to the continental slope and on the shelf was made. Con base en un modelo lineal, se estiman los principales parámetros de las mareas y ondas internas semidiurnas de altas frecuencias para la plataforma y pendiente continental cerca de las costas mexicanas de los estados de Jalisco y Colima. Por datos de la distribución vertical de la frecuencia de Brunt-Väisälä y por medio de cartas batimétricas actualizadas, se calculan las trayectorias de los flujos de energía (y) de la marea interna y la pendiente del fondo marino (α) en el talud continental, respectivamente. Se muestra que para la mayoría de las secciones del fondo se encuentran valores cercanos al crítico α/y ≈ l, lo cual testifica que existen las condiciones favorables para la generación de las mareas internas en el área de estudio de la costa del Océano Pacífico. Con base en el modelo de Baines (1982), se realizan los cálculos del flujo de energía de la onda barotrópica M2 a las ondas internas y se estiman sus amplitudes. Se muestra que los flujos de energía y amplitud de la marea interna dependen no sólo de la intensidad de la marea barotrópica, sino también de los ángulos de su llegada al borde de la plataforma.
