Meteotsunami in the United Kingdom: The hidden hazard

Clare Lewis, Tim Smyth, David Williams, Jess Neumann, and Hannah Cloke

Abstract. This paper examined the occurrence and seasonality of meteotsunami in the United Kingdom (UK) to present a revised and updated catalogue of events occurring since 1750. Previous case studies have alluded to a summer prevalence and rarity of this hazard in the UK. We have verified and classified 95 events using a developed set of identification criteria. The results have revealed a prominent seasonal pattern of winter events which are related to mid latitude depressions with precipitating convective weather systems. A geographical pattern has also emerged, highlighting three ‘hotspot’ areas at the highest risk from meteotsunami. The evidence reviewed, and new data presented here shows that the hazard posed by meteotsunami has been underestimated in the UK.

Short summary
Meteotsunami are globally occurring water waves initiated by sudden air pressure changes linked to cyclones, squalls, thunderstorms and atmospheric gravity waves. Previous research has suggested that in the UK, meteotsunami are rare waves generated by summer precipitating convective storms. However, this paper presents an up dated catalogue showing a larger percentage of winter events linked to small precipitating convective weather systems behind the cold fronts of mid latitude depressions.
