Meteotsunami

A meteotsunami is a tsunami-like wave driven not by the seafloor but by a moving atmospheric pressure or wind disturbance, such as a squall line or pressure jump. When the disturbance travels at the local shallow-water wave speed, Proudman resonance amplifies the sea-level wave, and harbor or shelf resonance can amplify it further. Periods range from minutes to a couple of hours, and damaging events have struck the Mediterranean, the Great Lakes, and the US East Coast.
