How are Meteotsunamis formed?

Meteotsunamis are generated when rapid changes in barometric pressure cause the displacement of a body of water. In contrast to "ordinary" impulse-type tsunami sources, a traveling atmospheric disturbance normally interacts with the ocean over a limited period of time (from several minutes to several hours).

What is the difference between a tsunami and a meteotsunami?

Meteotsunamis are large waves that scientists are just beginning to better understand. Unlike tsunamis triggered by seismic activity, meteotsunamis are driven by air-pressure disturbances often associated with fast-moving weather events, such as severe thunderstorms, squalls, and other storm fronts.Feb 26, 2021

What is the difference between a tsunami and a storm surge?

Superficially, the coastal effects from tsunamis and storm surges are quite similar, but dynamically they are very different. Tsunamis propagate through the deep oceans and strike the coastlines, whereas storm surges are only coastal phenomena and do not exist over the deeper part of the oceans.Apr 26, 2013

What are the effects of meteotsunamis?

  • Most meteotsunamis are too small to notice, but large meteotsunamis can have devastating coastal impacts (although not to the extreme of the 2004 Indian Ocean and 2011 Japan tsunamis). Damaging waves, flooding, and strong currents can last from several hours to a day and can cause significant damage, injuries, and deaths.

Do meteotsunamis exist in the Great Lakes?

  • Meteotsunamis occur all over the world — including the Great Lakes — but scientists are just beginning to better detect and understand them. In order to identify the meteotsunamis, which often go unrecorded, study researchers analyzed 22 years (1996-2017) of water level observations from 125 NOAA and partner tide gauges on the East Coast.

What is the strongest meteotsunami?

  • The strongest meteotsunami on record struck Vela Luka, Croatia, in June 1978. The event featured 19.5-foot wave heights, lasted several hours, and caused significant damage to the port and boats.
