Twenty-Seven Years of Progress in the Science of Meteorological Tsunamis Following the 1992 Daytona Beach Event

Meteorological tsunamis (meteotsunamis) are hazardous tsunami-like waves of atmospheric origin. They have typical periods from a few minutes to about 3 h and typical spatial scales from a few hundred meters to approximately 100-150 km. The waves have different local names in different regions of the world: rissaga in the Balearic Islands (Spain), marrobbio in Sicily (Italy), sciga in the Adriatic Sea (Croatia), milghuba in Malta, and abiki in Japan. Meteotsunamis have markedly different generation mechanisms than storm surge or rogue waves, and are mainly produced by direct air pressure forcing. Several recent destructive meteotsunami events have attracted considerable attention to the phenomenon. The present paper is one of the first attempts to classify and overview the strongest events. A total of 51 selected events over the past 27 years are examined and described. Some of these events are well known (e.g. the events of 4 July 1992 Daytona Beach, Florida, 15 June 2006 Ciutadella Harbour, Spain, and 13 June 2013 East Coast of USA), while others have only been mentioned in the media and on the Internet. The list of events includes those that have occurred in the Mediterranean, the Black Sea, Japan, South Korea, Australia, the Great Lakes, South Africa, the USA, Canada, Brazil, the Netherlands and other countries and regions. All meteotsunami events are separated into four groups: Good-weather harbour, Good-weather open-coast, Bad-weather harbour (storm seiches) and Bad-weather open-coast. Good-weather meteotsunamis are most typical for the Mediterranean region, while bad-weather events mainly occur on the Atlantic coasts of the USA and Europe.
