Tidal dynamics and energy budget in the Gulf of California

The dynamics and energetic behavior of the tides in the Gulf of California were studied with their principal constituents. Three cases were chosen: the first included the M2 constituent; the second, the two principal semidiurnal constituents; and the third, the seven most important tidal constituent...

description The dynamics and energetic behavior of the tides in the Gulf of California were studied with their principal constituents. Three cases were chosen: the first included the M2 constituent; the second, the two principal semidiurnal constituents; and the third, the seven most important tidal constituents in the gulf. The results show that the tide was successfully modeled for all constituents and for all cases. It was proved that small changes in the friction coefficient produce important errors in the tidal adjustment. The dynamics and energetic behavior of the tides did not change while varying the friction coefficient, even when more constituents were included. The most important forces that maintain the momentum balance in the gulf are the pressure gradient, Coriolis and friction. In the northern gulf the most important forces are the pressure gradient and friction, while in the southern gulf the most important forces are in geostrophic balance. Advection is also important in the northern gulf and in the archipelago of the large islands. The regions where most of the tidal energy is dissipated are the northern gulf and the archipelago, especially in the Upper Gulf, Adair Bay, Ballenas Channel, and San Lorenzo and San Esteban sills. The inclusion of more constituents introduced more momentum and energy to the gulf, and part of this momentum and energy was transferred to the mean field and part to the low-frequency field. The results show that changes in the friction coefficient did not affect the tidal behavior in the gulf; nevertheless, the tidal energy dissipation estimated inside the gulf was affected.

Se estudió numéricamente el comportamiento dinámico y energético de la marea en el Golfo de California a partir de sus principales componentes. Se escogieron tres casos: el primero incluyó la componente M2; el segundo, las dos principales componentes semidiurnas; y el tercero, las siete componentes más importantes de la marea en el golfo. Los resultados muestran que el modelado de la marea fue satisfactorio para todas las componentes y para todos los casos. Se probó que pequeñas variaciones del coeficiente de fricción produjeron errores importantes en el ajuste de la marea. El comportamiento dinámico y energético de la marea no cambió al variar el coeficiente de fricción ni al incluir más componentes. Las fuerzas más importantes que mantienen el balance de momento en todo el golfo son el gradiente de presión, Coriolis y la fricción. En la región norte las fuerzas más importantes son el gradiente de presión y la fricción, mientras que en el sur del golfo las fuerzas más importantes están en balance geostrófico. La advección también es importante en la región norte y en el archipiélago de las grandes islas. Las regiones donde se disipa la mayor parte de la energía proveniente de la marea son la región norte y el archipiélago de las grandes islas, principalmente en el Alto Golfo, en Bahía Adair, en el Canal de Ballenas y en los umbrales de San Lorenzo y San Esteban. La inclusión de más componentes introdujo una mayor cantidad de momento y energía al golfo; parte de este momento y energía fue transferido al promedio y parte a frecuencias bajas. Los resultados muestran que la variación del coeficiente de fricción no afectó el comportamiento de la marea en el golfo, pero sí la estimación de la energía que se disipa en promedio dentro de él.
