英文摘要: Several strong sea-level oscillations in the southern region of Brazil with periods in the range of tsunamis, but attributed to atmospheric disturbances, have been publicized in the media or in scientific articles in recent years. However, only a few were registered by instruments. On October 29, 2019, a squall line, linked to an atmospheric storm and a positive jump in atmospheric pressure, spread from south to north along the coast of Santa Catarina. The atmospheric disturbance generated, through Proudman's resonance mechanism, at least two tsunami-like waves with heights greater than 0.70 m and periods around 15 min. These waves were recorded by a network of tide gauges, allowing to monitor their evolution and transformations for more than 200 km. Although there were no reported fatalities, there were significant material losses linked to this occurrence. The objective of the present work is to analyze and connect atmospheric conditions and wave signals in order to further understand the circumstances leading to the formation of this type of event in the southern coast of Brazil. © 2020, Springer Nature B.V.
