“…Meteotsunami generation and propagation. We used a method to analyze the meteotsunami propagation and generation inspired by Sheremet et al 42 . This method consists in the computation of the meteotsunami generation, evolution, and propagation coefficients along wave rays.…”

“…This method consists in the computation of the meteotsunami generation, evolution, and propagation coefficients along wave rays. To compute the wave rays we used a method that differs from Sheremet et al 42 . In this specific case, we filtered the barotropic velocities and water elevations at the meteotsunami frequency band from the ROMS outputs.…”

Tropical cyclone rainbands can trigger meteotsunamis

et al. 2020

Tropical cyclones are one of the most destructive natural hazards and much of the damage and casualties they cause are flood-related. Accurate characterization and prediction of total water levels during extreme storms is necessary to minimize coastal impacts. While meteotsunamis are known to influence water levels and to produce severe consequences, their impacts during tropical cyclones are underappreciated. This study demonstrates that meteotsunami waves commonly occur during tropical cyclones, and that they can contribute significantly to total water levels. We use an idealized coupled ocean-atmosphere-wave numerical model to analyze tropical cyclone-induced meteotsunami generation and propagation mechanisms. We show that the most extreme meteotsunami events are triggered by inherent features of the structure of tropical cyclones: inner and outer spiral rainbands. While outer distant spiral rainbands produce single-peak meteotsunami waves, inner spiral rainbands trigger longer lasting wave trains on the front side of the tropical cyclones.

“…Multiple meteotsunamis in the study of Monserrat et al (2006) are also associated with atmospheric pressure anomaly of around 5 HPa. In addition, the meteotsunami events described by Olabarrieta et al (2017) and Sheremet et al (2016) involve one primary large wave (soliton) sometimes followed by large waves with rapidly decaying amplitudes (over a few minutes and with periods of incident waves). In contrast, the January 16, 2016 runup events, as evident by video footage and water level measurements, are recurring events with periods an order of magnitude larger than incident waves and with sustained amplitude over multiple hours.…”

Abstract. Extreme, tsunami-like wave runup events in the absence of earthquakes or landslides have been attributed to trapped waves over shallow bathymetry and long waves created by atmospheric disturbances. These runup events are associated with inland excursions of hundreds of meters and periods of minutes. While the theory of radiation stress implies that nearshore energy transfer from the carrier waves to the infragravity waves can also lead to very large runup, there have not been observations of runup events induced by this process with magnitudes and periods comparable to the other two mechanisms. This work presents observations of several runup events in the U.S. Pacific Northwest that are comparable to extreme runup events related to trapped waves and atmospheric disturbances. It also discusses possible generation mechanisms and shows that energy transfer from incident waves to bound infragravity waves is a plausible generation mechanism. In addition, a method to predict and forecast extreme runup events with similar characteristics is presented.

“…Observational networks have indeed expanded globally (e.g., IOC Sea Level Station Monitoring Facility network (http://www.ioc-seale velmo nitor ing.org/) or regionally (e.g., NOAA Tides and Currents, https ://tides andcu rrent s.noaa.gov), enabling for mapping of high-frequency sea level oscillations and meteotsunamis in all continents (Rabinovich 2020). In recent years, a great number of meteotsunami studies have been carried out around the world based on observations, modelling and analysis of source processes and in relation to geographical location and local processes (Pellikka et al 2014;Linares et al 2016Linares et al , 2019Sheremet et al 2016;Olabarrieta et al 2017;Dusek et al 2019;Kim et al 2019;Williams et al 2019;Heidarzadeh et al 2020;Shi et al 2019Shi et al , 2020, which can produce meteotsunamis of different origins than those in the Mediterranean (e.g., frontal zones, hurricanes).…”

The Mediterranean and Black Sea meteotsunamis: an overview

et al. 2020

View full text Add to dashboard Cite

This paper presents the first comprehensive review of the Mediterranean and Black Sea meteorological tsunamis or meteotsunamis (atmospherically induced destructive long ocean waves in the tsunami frequency band) based on the available literature, tools and services. The Mediterranean and Black Seas are micro-tidal basins; therefore, rapid sea level changes in the tsunami frequency band may strongly affect coastal regions and infrastructures and endanger human lives. The review also includes a succinct bibliography of Mediterranean and Black Sea meteotsunami papers and evaluates their structure in respect to geographical extent, the type of tools used (observations versus modelling) and source processes in the atmosphere versus ocean manifestations. This review continues with a presentation of major meteotsunami events and a discussion about their sources, the resonant transfer of energy towards the sea, their propagation towards shore and their interactions with bathymetry. Meteotsunami monitoring and forecasting systems are overviewed with respect to available observations, deterministic and stochastic modelling tools and operational early warning networks. This review includes an important assessment of operational and research gaps and ideas for improving research tools and understanding of various aspects of meteotsunamis. The authors believe and hope that this review will help researchers and services to increase or improve their capacities and skills for conducting better research on meteotsunamis, not just in the Mediterranean and Black Seas, but in all ocean basins around the world affected by this destructive and dangerous phenomenon.
