Spectral variability in high frequency in sea level and atmospheric pressure on Buenos Aires Coast, Argentina

Abstract: There are some observational evidences which support that atmospheric gravity waves constitute an efficient forcing for meteorological tsunamis (meteotsunamis) along the coast of Buenos Aires, Argentina. Meteotsunamis and atmospheric gravity waves, which propagate simultaneously on the sea surface and the atmosphere, respectively, are typical examples of non-stationary geophysical signals. The variability of meteotsunamis and atmospheric gravity waves recorded at Mar del Plata was investigated in this paper. R… Show more

“…They are related to a wide variety of atmospheric disturbances, mostly due to the passage of a low pressure system and a cold front on the Ligurian basin, determining conditions of strong instability. Frequently, atmospheric gravity waves are linked to similar patterns [59][60][61][62][63][64]. The number and intensity of these meteotsunamis strongly differ from one year to another and, although the time series is not long enough for a significant statistical analysis, a slight increasing trend in the recent years may have been detected.…”
