The generation of long waves due to air-pressure change was numerically simulated in model basins of uniform water depth, as well as East Chine Sea, where the location of air-pressure change moved in the eastern direction, using a nonlinear shallow-water model. Long waves of large wave height require larger change rate of air pressure. If the moving velocity of the location of air-pressure change is larger than the celerity of shallow-water waves, the wave height of generated long waves is not so large, while the wavelength becomes longer. The long-wave train increases the wave height near Kamikoshiki Island. The air-pressure change was simply assumed according to the air-pressure data actually observed on an island, resulting in a long-wave period close to that of the oscillation mode in Urauchi Bay, Kamikoshiki Island.
