Despite being protected from ocean waves, the lagoon, which is popular with tourists, is a dangerous place to swim, with an average of 8-9 drownings each year. The present paper examines the longshore and rip currents in the lagoon as the potential cause for these fatalities. Drifters were deployed for measuring the magnitude and direction of the nearshore currents. Unidirectional, northwards, longshore currents, with velocity up to 1.4ms-1 and strong rip currents, with velocity up to 3.4ms-1, 5-10m width and duration of less than 5 minutes, were observed.

  • Meteotsunami Generation, Amplification and Occurrence in North-West Europe
    University of Liverpool Doctoral Thesis Meteotsunami generation, amplification and occurrence in north-west Europe Thesis submitted in accordance with the requirements of the University of Liverpool for the degree of Doctor in Philosophy by David Alan Williams November 2019 ii Declaration of Authorship I declare that this thesis titled “Meteotsunami generation, amplification and occurrence in north-west Europe” and the work presented in it are my own work. The material contained in the thesis has not been presented, nor is currently being presented, either wholly or in part, for any other degree or qualification. Signed Date David A Williams iii iv Meteotsunami generation, amplification and occurrence in north-west Europe David A Williams Abstract Meteotsunamis are atmospherically generated tsunamis with characteristics similar to all other tsunamis, and periods between 2–120 minutes. They are associated with strong currents and may unexpectedly cause large floods. Of highest concern, meteotsunamis have injured and killed people in several locations around the world. To date, a few meteotsunamis have been identified in north-west Europe. This thesis aims to increase the preparedness for meteotsunami occurrences in north-west Europe, by understanding how, when and where meteotsunamis are generated. A summer-time meteotsunami in the English Channel is studied, and its generation is examined through hydrodynamic numerical simulations. Simple representations of the atmospheric system are used, and termed synthetic modelling. The identified meteotsunami was partly generated by an atmospheric system moving at the shallow- water wave speed, a mechanism called Proudman resonance. Wave heights in the English Channel are also sensitive to the tide, because tidal currents change the shallow-water wave speed.

Meteotsunami occurrence in the Gulf of Finland over the past century Havu Pellikka1, Terhi K. Laurila1, Hanna Boman1, Anu Karjalainen1, Jan-Victor Björkqvist1, and Kimmo K. Kahma1 1Finnish Meteorological Institute, P.O. Box 503, FI-00101 Helsinki, Finland Correspondence: Havu Pellikka (havu.pellikka@fmi.fi) Abstract. We analyse changes in meteotsunami occurrence over the past century (1922–2014) in the Gulf of Finland, Baltic Sea. A major challenge for studying these short-lived and local events is the limited temporal and spatial resolution of digital sea level and meteorological data. To overcome this challenge, we examine archived paper recordings from two tide gauges, Hanko for 1922–1989 and Hamina for 1928–1989, from the summer months of May–October. We visually inspect the recordings to 5 detect rapid sea level variations, which are then digitized and compared to air pressure observations from nearby stations. The data set is complemented with events detected from digital sea level data 1990–2014 by an automated algorithm. In total, we identify 121 potential meteotsunami events. Over 70 % of the events could be confirmed to have a small jump in air pressure occurring shortly before or simultaneously with the sea level oscillations. The occurrence of meteotsunamis is strongly connected with lightning over the region: the number of cloud-to-ground flashes over the Gulf of Finland were on 10 average over ten times higher during the days when a meteotsunami was recorded compared to days with no meteotsunamis in May–October.

In particular, meteotsunamis occurring in the Yellow Sea caused unexpected casualties and property damage to local communities on the western coast of the Korean Peninsula in 2007 and 2008. These events attracted the attention of many engineers and scientists because abrupt extreme waves have struck several coasts and ports even under fine weather conditions. Furthermore, the Yellow Sea has the highest tide and most powerful tidal currents in the world, and consequently, meteotsunami events there could be more destructive and harmful to local coastal communities when such events occur during high tide or a critical phase with strong tidal currents. In this study, numerical experiments were conducted to identify the qualitative effect of the interaction between a meteotsunami and the tide on the generation and amplification mechanisms of meteotsunamis occurring in the Yellow Sea. In general, small-scale meteotsunamis, such as those that occur in the Yellow Sea, should be analyzed using a high-resolution modeling system because water motions can be affected by local terrain.

Abstract This manual presents tools for the planning, design, and operation of highways in the coastal environment. It focuses on roads near the coast that are influenced by coastal tides and waves constantly, or occasionally during storms. FHWA estimates that there are more than 60,000 miles of these “coastal highways” in the US. A primary goal is the integration of coastal engineering principles and practices in the planning and design of these roads and bridges to make them more resilient.

HUGHES a Department of Earth, Ocean and Ecological Sciences, University of Liverpool, Liverpool, United Kingdom b Department of Earth and Environmental Sciences, University of Manchester, Manchester, United Kingdom c National Oceanography Centre, Liverpool, United Kingdom (Manuscript received 1 August 2020, in final form 29 November 2020) ABSTRACT: Meteotsunamis are shallow-water waves that, despite often being small (;0.3 m), can cause damage, in- 2 juries, and fatalities due to relatively strong currents (.1ms 1). Previous case studies, modeling, and localized climatol- ogies have indicated that dangerous meteotsunamis can occur across northwest Europe. Using 71 tide gauges across northwest Europe between 2010 and 2017, a regional climatology was made to understand the typical sizes, times, and atmospheric systems that generate meteotsunamis. A total of 349 meteotsunamis (54.0 meteotsunamis per year) were identified with 0.27–0.40-m median wave heights. The largest waves (;1 m high) were measured in France and the Republic of Ireland. Most meteotsunamis were identified in winter (43%–59%), and the fewest identified meteotsunamis occurred in either spring or summer (0%–15%). There was a weak diurnal signal, with most meteotsunami identifications between 1200 and 1859 UTC (30%) and the fewest between 0000 and 0659 UTC (23%). Radar-derived precipitation was used to identify and classify the morphologies of mesoscale precipitating weather systems occurring within 6 h of each meteotsunami.
