From AMS Glossary
(Also called meteorological tsunami.) A tsunami-like wave phenomenon generated by a meteorological or atmospheric disturbance.
Meteotsunami are caused by traveling air pressure disturbances associated with atmospheric gravity waves, pressure jumps, frontal passages, squalls, gales, typhoons, hurricanes, and other atmospheric sources. These generate barotropic ocean waves in the open ocean through resonance, which can subsequently be amplified near the coast through shoaling and basin resonance.
