Abstract
Atmosferski val nastao uslijed erupcije Hunga Tonga–Hunga Haʻapai vulkana 15.1.2022. više je puta obišao Zemlju, pa je tako imao utjecaj i na mediteransko područje izazivajući meteorološki tsunami (tsunami izazvan promjenama u atmosferskom tlaku). Promatrani su podaci o razini mora i tlaku zraka za odabrane postaje u vremenskom periodu od 13.1.2022. do 19.1.2022., kako bi se odredila njihova povezanost. Pri crtanju originalnih i filtriranih nizova razine mora i tlaka zraka može se jasno primijetiti dolazak prvog i drugog vala za većinu odabranih postaja. Iz filtriranih nizova određena su vremena dolaska valova te pripadajuće amplitude. Promatrana je brzina dugih valova u moru koja je proporcionalna dubini mora, te je uspoređena s brzinom atmosferskog vala. Što su ove brzine bliže jedna drugoj po iznosu, veće je pojačavanje valova u moru (Proudmanova rezonancija). Omjer brzine dugih valova i atmosferskog vala (Freudov broj) slaže se s amplitudama razine mora na način da su amplitude razine mora najveće upravo tamo gdje je ovaj omjer što bliži jedinici.
Abstract (english)
The atmospheric wave generated by the eruption of the Hunga Tonga-Hunga Haʻapai volcano on January 15, 2022, circumnavigated the Earth multiple times, thereby impacting the Mediterranean region and triggering meteorological tsunamis (tsunamis induced by atmospheric pressure changes). Data on sea level and air pressure were observed for selected stations within the time frame from January 13, 2022, to January 19, 2022, to determine their correlation. When plotting the original and filtered time series of sea level and air pressure, the arrival of the first and second wave is prominently noticeable for most selected stations. From the filtered time series, wave arrival times and their corresponding amplitudes were determined. The speed of long ocean waves is proportional to water depth and is compared with the speed of the atmospheric wave. When these two speeds are close in magnitude, wave amplification occurs in the ocean, a phenomenon known as Proudman resonance. The ratio of the speed of long ocean waves and atmospheric wave (Froude number) corresponds to sea level amplitudes, with the sea level amplitudes being highest when this ratio approaches unity.
