“…An attempt to take into account the effect of such coupling has so far only been made by Renault et al (2011) for the region of the Balearic Islands, however, simulated ocean wave heights at Ciutadella, the main Balearic meteotsunami "hot spot, " were significantly underestimated. Therefore, this is a principal issue where substantial advancement is needed in the future.…”

“…Present coupled atmospheric-oceanic models are able to provide qualitative reproduction of meteotsunami waves, but still underestimate their amplitude and the potential for damage (Renault et al, 2011). This is because these models do not describe properly the evolution of tsunamigenic disturbances propagating onshore.…”

The understanding of meteotsunamis-significant atmospherically generated long ocean waves in the tsunami frequency band-has advanced considerably during the last two decades. Scientists and specialists use near-field in situ data and remote observations, as well as atmospheric and ocean modeling, to study destructive events. The phenomenon has been reported and investigated worldwide, indicating its relevance as a marine natural hazard and demonstrating the urgent need for meteotsunami warning systems for certain countries. In this paper we summarize the present knowledge of the phenomenon, identify particular research gaps, and propose near-future critical components of meteotsunami research. We emphasize a potential concept of merging yet-to-be-developed meteotsunami warning systems and existing tsunami or multi-hazard early warning systems.

“…Based on meteotsunami statistics from Ciutadella inlet, in the Balearic Islands, showed that meteotsunamis with amplitudes higher than 0.2 m, 0.5 m, and 3-4 m ('rissaga' events) occurred every summer, once every 5-6 years, and once every 15-20 years, respectively. Since 1984, the Spanish National Institute of Meteorology has been using weather predictions and numerical simulations to forecast meteotsunamis (Jansa et al 2007;Renault et al 2011).…”

Tide gauge data were used to identify the occurrence, characteristics, and cause of tsunamis of meteorological origin (termed 'meteotsunamis') along the Western Australian coast. This is the first study to identify meteotsunamis in this region, and the results indicated that they occur frequently. Although meteotsunamis are not catastrophic to the extent of major seismically induced basin-scale events, the wave heights of meteotsunamis examined at some local stations in this study were higher than those recorded through seismic tsunamis. In June 2012, a meteotsunami contributed to an extreme water-level event at Fremantle, which recorded the highest water level in over 115 years. Meteotsunamis (wave heights [0.4 m, when the mean tidal range in the region is *0.5 m) were found to coincide with thunderstorms in summer and the passage of low-pressure systems during winter. Spectral analysis of tide gauge time series records showed that existing continental seiche oscillations (periods between 30 min and 5 h) were enhanced during the meteotsunamis, with a high proportion of energy transferred to the continental shelf oscillation period. Three recent meteotsunami events (22 March 2010, 10 June 2012, and 7 January 2013) two due to summer thunderstorms and one due to a winter frontal system were chosen for detailed analysis. The meteotsunami amplitudes were up to a factor 2 larger than the local tidal range and sometimes contributed up to 85 % of the non-tidal water signal. A single meteorological event was found to generate several meteotsunamis along the coast, up to 500 km apart, as the air pressure disturbance propagated over the continental shelf; however, the topography and local bathymetry of the continental shelf defined the local sea-level resonance characteristics at each location. With the available data (sea level and meteorological), the exact mechanisms for the generation of the meteotsunamis could not be isolated.

“…Atmospheric gravity waves are another common cause of meteotsunamis worldwide (Monserrat et al 1991), as exemplified by the 2008 Boothbay event . It is more difficult to parameterize these sources, short of performing high-resolution mesoscale modeling (Renault et al 2011;Vilibić et al 2013;Horvath and Vilibić 2014). In addition, it is unclear if enough data are available to construct distributions of the parameters that control atmospheric gravity waves.…”

A probabilistic technique is developed to assess the hazard from meteotsunamis. Meteotsunamis are unusual sea-level events, generated when the speed of an atmospheric pressure or wind disturbance is comparable to the phase speed of long waves in the ocean. A general aggregation equation is proposed for the probabilistic analysis, based on previous frameworks established for both tsunamis and storm surges, incorporating different sources and source parameters of meteotsunamis. Parameterization of atmospheric disturbances and numerical modeling is performed for the computation of maximum meteotsunami wave amplitudes near the coast. A historical record of pressure disturbances is used to establish a continuous analytic distribution of each parameter as well as the overall Poisson rate of occurrence. A demonstration study is presented for the northeast U.S. in which only isolated atmospheric pressure disturbances from squall lines and derechos are considered. For this study, Automated Surface Observing System stations are used to determine the historical parameters of squall lines from 2000 to 2013. The probabilistic equations are implemented using a Monte Carlo scheme, where a synthetic catalog of squall lines is compiled by sampling the parameter distributions. For each entry in the catalog, ocean wave amplitudes are computed using a numerical hydrodynamic model. Aggregation of the results from the Monte Carlo scheme results in a meteotsunami hazard curve that plots the annualized rate of exceedance with respect to maximum event amplitude for a particular location along the coast. Results from using multiple synthetic catalogs, resampled from the parent parameter distributions, yield mean and quantile
