A meteotsunami or meteorological tsunami is a tsunami-like wave phenomenon of meteorological origin. Tsunamis and meteotsunamis propagate in the water in the same way and have the same coastal dynamics. In other words, for an observer on the coast where it strikes the two types would look the same. The difference is in their source only. One definition of a meteotsunami is as an atmospherically generated large amplitude seiche oscillation.
These tsunami-like ocean waves are principally caused by traveling air pressure disturbances, including those associated with atmospheric gravity waves, roll clouds, pressure jumps, frontal passages, and squalls, which normally generate barotropic ocean waves in the open ocean and amplify them near the coast through specific resonance mechanisms. In contrast to "ordinary" impulse-type tsunami sources, a travelling atmospheric disturbance normally interacts with the ocean over a limited period of time (from several minutes to several hours).

Speed of a meteotsunami
In the Western Atlantic, a meteotsunami’s deep water speed can reach 732 km/h (455 mph). This value is equivalent to the long-wave speed of a barotropic wave at a depth of 4200 m.
