“…This hazard has so far been underrated (Pattiaratchi and Wijeratne, 2015), primarily due to a lack of sea-level measurements at a minute timescale. Fortunately, the "rate" of the research on high-frequency sea-level oscillations, in particular on meteotsunamis, strongly increased in recent years (Vilibić et al, 2021). It is not certain how will highfrequency sea-level oscillations change under the future climate scenarios, although there is at least one research stating that these oscillations might become more frequent and of higher magnitude (Vilibić et al, 2018).…”

Abstract. Sea-level observations provide information on a variety of processes occurring over different temporal and spatial scales that may contribute to coastal flooding and hazards. However, global research of sea-level extremes is restricted to hourly datasets, which prevent quantification and analyses of processes occurring at timescales between a few minutes and a few hours. These shorter period processes, like seiches, meteotsunamis, infragravity and coastal waves, may even dominate in low-tidal basins. Therefore, a new global 1-minute sea-level dataset – MISELA (Minute Sea-Level Analysis) – has been developed, encompassing quality-checked records of nonseismic sea-level oscillations at tsunami timescales (T < 2 h) obtained from 331 tide-gauge sites (https://doi.org/10.14284/456, Zemunik et al., 2021b). This paper describes data quality-control procedures applied to the MISELA dataset, world and regional coverage of tide-gauge sites and lengths of time-series. The dataset is appropriate for global, regional or local research of atmospherically-induced high-frequency sea-level oscillations, which should be included in the overall sea-level extremes assessments.

“…and thus the true scale of the hazards associated with meteotsunamis are not represented. Therefore, as meteotsunami forecasting is still in its early development, or non-existent in most regions of the world, it is critical to understand the modeling requirements for resolving these processes to develop robust forecast systems (Angove et al 2021;Vilibić et al 2021).…”

“…The Great Lakes are a known hot-spot of meteotsunami activity (Bechle et al 2016;Vilibić et al 2021), yet there is currently no available forecast system or detection system in place for meteotsunami conditions. As such, the Great Lakes serve as an important region for investigation of essential processes in meteotsunami flooding and forecast requirements.…”

“…While various mechanisms, such as storm surges and seiches, can result in coastal flooding in the Great Lakes and coastal oceans, meteotsunamis are an important phenomenon that have caused disastrous damage to coastal property and loss of life due to their significant runup and associated strong currents (As-Salek and Schwab 2004;Šepić et al 2015;Linares et al 2019;Vilibić et al 2021). These meteorologically induced water waves are similar to seismic tsunamis in spatial and temporal characteristics, limited to the frequency band of wave periods between 2 minutes to 2 hours, but are mainly caused by atmospheric pressure and wind perturbations associated with fast-moving weather events including severe thunderstorms, squalls and storm fronts (Vilibić et al 2021). These atmosphericdisturbance-generated waves are often amplified by different resonance mechanisms such as the Proudman resonance, Greenspan resonance, shelf resonance and harbor resonance (Monserrat et al 2006).…”

Evaluating essential processes and forecast requirements for meteotsunami-induced coastal flooding

Meteotsunamis pose a unique threat to coastal communities and often lead to damage of coastal infrastructure, deluge of nearby property, and loss of life and injury. The Great Lakes are a known hot-spot of meteotsunami activity and serve as an important region for investigation of essential hydrodynamic processes and model forecast requirements in meteotsunami-induced coastal flooding. For this work, we developed an advanced hydrodynamic model and evaluate key model attributes and dynamic processes, including: (1) coastal model grid resolution and wetting and drying process in low-lying zones, (2) coastal infrastructure, including breakwaters and associated submerging and overtopping processes, (3) annual/seasonal (ambient) water level change, and (4) wind wave-current coupling. Numerical experiments are designed to evaluate the importance of these attributes to meteotsunami modeling, including a “representative storm” scenario in the context of regional climate change in which a meteotsunami wave is generated under high ambient lake-level conditions with a preferable wind direction and speed for wind-wave growth. Results demonstrate that accurate representation of coastal topography and fully resolving associated hydrodynamic processes are critical to forecasting the realistic hazards associated with meteotsunami events. As most of existing coastal forecast systems generally do not resolve many of these features due to insufficient model grid resolution or lack of essential model attributes, this work shows that calibrating or assessing existing forecast models against coastal water level gauges alone may result in underestimating the meteotsunami hazard, particularly when gauging stations are sparse and located behind harbor breakwaters or inside estuaries, which represent dampened or otherwise unrepresentative pictures of meteotsunami intensity. This work is the first hydrodynamic modeling of meteotsunami-induced coastal flooding for the Great Lakes, and serves as a template to guide where resources may be most beneficial in forecast system development and implementation.

“…As a result, sea level oscillations in the open sea of several centimetres can be amplified up to destructive amplitudes of several meters high along the shoreline. The pressure-forced meteotsunami occurrences, which are known to have temporal and spatial occurrences more frequent than seismic tsunamis (Pattiaratchi and Wijeratne, 2015), have been steadily reported worldwide until recently (Vilibić et al, 2021).…”

Abstract. The eastern Yellow Sea meteotsunami occurrences between 2010 and 2019 and guidelines derived using favourable conditions of pressure disturbance (10 min rate of air pressure change) for meteotsunami generation are described. A total of 34 meteotsunami events over the past decade can be classified based on a current meteotsunami monitoring and observation system. 1 min intervals of mean sea level pressure and sea level observations from 89 meteorological stations and 16 tide gauges are analysed. Most of the classified meteotsunami events (76 %, 26/34) in the eastern Yellow Sea are found to be between February and June during the winter-to-summer transition, which shows a strong seasonal trend. The meteotsunami occurrences are spatially frequent at the DaeHeuksando (DH) tide gauge, known as a beacon tide gauge of the observation system. It appears that the specific characteristics (intensity, occurrence rate, and propagation) of the pressure disturbance are in common on extreme meteotsunami events that are classified by applying the hazardous meteotsunami conditions among the 34 events. For a risk level assessment of the eastern Yellow Sea meteotsunami occurrences, favourable conditions of the pressure disturbance for meteotsunami generation are utilized. Overall, this study can provide useful and practical guidelines such as operation period, potential hot spot, and risk level to monitoring system operators when operating the monitoring system of the Yellow Sea.
