Resumen

En este trabajo estudiamos la influencia de la topografía en la respuesta oceánica generada por una perturbación atmosférica en movimiento y la importancia de la dirección de propagación de ésta en la generación de meteotsunamis. Para ello, se analiza la respuesta de la superficie del mar en la bocana de dos puertos ubicados en sistemas insulares utilizando un modelo de circulación de ecuaciones primitivas. Para diferentes ángulos de incidencia de la perturbación atmosférica, se estudia la amplitud de la respuesta espectral a la frecuencia de resonancia de cada uno de los puertos. Los resultados numéricos proporcionan amplificaciones máximas en cada uno de los puertos para ángulos que concuerdan con las observaciones.
