A meteotsunami is generated by an atmospheric pressure disturbance traveling across the sea (Renault et al. 2011; Vilibic´ et al. 2008; Monserrat and Thorpe 1996; Rabinovich and Monserrat 1996; Monserrat et al.2006; Asano et al. 2012). Explained simply, a low-/high-pressure center (or edge) moving at a given velocity attempts to produce a peak/trough under it on the sea traveling at the same speed. This can generate a freely propagating surface gravity wave that increases in amplitude when the speed of the atmospheric anomaly v _aa matches the phase velocity of a shallow-water wave v _ph(d) given by (1)

 

An unusual storm system moved eastward across the country on, commonly called a “derecho”, and appears to have launched a meteotsunami that impacted the US East Coast. Meteotsunamis occur frequently in the Mediterranean region (Adriatic, Aegean, and Black Seas) (Renault et al. 2011; Vilibic´ et al. 2008), but are rarely mentioned in the USA. The existence of the meteotsunami was confirmed by several of the 30 tide gauges along the East Coast up through New England and was seen as far away as Puerto Rico and Bermuda. A NOAA DART buoy was triggered by the event, as well as another bottom-pressure sensor-of-opportunity in the region, a Sonardyne bottom-pressure recording (Hammond2013). All of these outputs give a measure of the meteotsunami height.
