“…This may be particularly interesting to the local authorities, as some of these oscillations are observed in large harbours, prone to heavy ship and cargo traffic (Wang et al, 1987;de Jong and Battjes, 2004;Vilibić and Mihanović, 2005). For instance, Wang et al (1987) studied 23-yr-long sea level time series in the Bohai Bay (China) and documented statistics of all identified strong seiche events, enabling an estimation of seiche return periods. Applying this procedure to all stations along the US coastline (and not only there) would allow a delimitation of "high risk" areas.…”

A systematic survey of high-frequency sea level oscillations (<6 h) measured between 2006 and 2011 along the US East Coast is performed. Raw 1-min resolution sea level data is used. After performing a data quality check, the nine most intense events, with maximum recorded wave heights ranging from 40 to 100 cm, are identified. Focusing on three of these events enables us to recognize two different generation mechanisms: (i) topographically-trapped edge waves which are found to be a significant contributor to the strongest observed oscillations, and (ii) standing waves, which occur over enclosed shallow waters and may result in significant wave heights of up to 100 cm. A reproduction of the observed oscillations is a part of a future work, which will include an assessment of a generating force in the atmosphere, allowing for a better prevention of potential flooding along the US East Coast

“…No other such sites exists in China. Wang et al (1987) examined 23 years of continuous tide gauge records (1957-1958 and 1961-1981) and selected 137 events when maximum troughto-crest wave heights were greater than 40 cm. Most of these events were found to occur in May-August, while in winter months (January-February) strong seiches were never observed.…”

“…The mean duration of the events is from 2 to 4 h (maximum observed duration was 9 h) but the observed periods are not as consistent as in Nagasaki Bay where the most common periods are 85 and 115 min. Over the 23-year observational period, there were 13 events with maximum wave heights more than 100 cm, with the strongest event occurring on 1 September 1980 when the recorded seiche wave height was 293 cm (Wang et al, 1987;see also Fig. 1b in Rabinovich and Monserrat, 1996).…”

Abstract. In light of the recent enhanced activity in the study of tsunami waves and their source mechanisms, we consider tsunami-like waves that are induced by atmospheric processes rather than by seismic sources. These waves are mainly associated with atmospheric gravity waves, pressure jumps, frontal passages, squalls and other types of atmospheric disturbances, which normally generate barotropic ocean waves in the open ocean and amplify them near the coast through specific resonance mechanisms (Proudman, Greenspan, shelf, harbour). The main purpose of the present study is to describe this hazardous phenomenon, to show similarities and differences between seismic and meteorological tsunamis and to provide an overview of meteorological tsunamis in the World Ocean. It is shown that tsunamis and meteotsunamis have the same periods, same spatial scales, similar physical properties and affect the coast in a comparably destructive way. Some specific features of meteotsunamis make them akin to landslide-generated tsunamis. The generation efficiency of both phenomena depend on the Froude number (Fr), with resonance taking place when Fr∼1.0. Meteotsunamis are much less energetic than seismic tsunamis and that is why they are always local, while seismic tsunamis can have globally destructive effects. Destructive meteotsunamis are always the result of a combination of several resonant factors; the low probability of such a combination is the main reason why major meteotsunamis are infrequent and observed only at some specific locations in the ocean.

“…Nevertheless, little attention was paid to this phenomenon by specialists in natural hazards till the middle of the 1990s. Usually, it was considered to be a very local effect occurring in a few particular bays or harbours: Nagasaki Bay in Japan (Hibiya and Kajiura 1982;Akamatsu 1982), Ciutadella Harbour in Menorca Island, Balearic Islands, Spain (Tintoré et al 1988;Monserrat et al 1991;Gomis et al 1993), Longkou Harbour in China (Wang et al 1987), Vela Luka and some other bays in Croatia (Hodžić 1979(Hodžić /1980Orlić 1980) and Mazaro del Vallo harbour on the western coast of Sicily (Colucci and Michelato 1976;Candela et al 1999). The publications of Rabinovich andMonserrat (1996, 1998) attracted the interest of tsunami scientists to this type of oscillation.…”
