Abstract

Meteotsunamis have frequently been excited in bays and harbors along west coast of Kyushu during early spring time. Makurazaki harbor has also been suffered by meteotsunami disturbances, although its mouth does not open east wards. The present study investigates the possibility of a resonant coupling between atmospheric disturbance and geometric edge waves trapped on the continental shelf. A field observation was conducted by deploying three tidal gauges along the coast. The measured predominant spectral peaks and phase patterns were discussed by referring the theoretically predicted ones for the trapped waves on the shelf.
