Rutgers Detects Meteotsunami
June 4, 2020
Rutgers scientists observed the ocean and atmospheric response to a derecho that passed through NJ and caused severe damage in several towns. A Rutgers meteorological tower in Tuckerton NJ recorded a peak wind gust of 54 mph alongside a 21-degree temperature drop in only 15 minutes. The HF-Radar station at Bradley Beach, NJ, part of the larger Mid-Atlantic Regional Association Coastal Ocean Observing System network, detected a surface disturbance at 1:20 pm local and the station in Brant Beach registered a similar response thirty minutes later at 1:50 pm local. This time delay was the result of the southeast track of the storm first reaching the northern station at Bradley Beach and then reaching the southern station in Brant Beach. This event is similar to another a meteotsunami that Rutgers detected in 2013 which sent several people to the hospital. NOAA estimates that 25 meteotsunamis impact the east coast of the United States each year.
