Only three days after the previous event, during 14-15 May 2020, meteotsunamis again occurred at Vrboska and Vela Luka. Descriptive information on Vrboska event come from on-line articles and YouTube (YouTube, 15 May 2020<\/a>). According to these, strong sea-level oscillations were observed during early afternoon hours of 14 May. The oscillations had 5-6 min period and resulted in drying and 30-cm flooding of the bay. In Vela Luka, sea-level oscillations caused drying and flooding of the inner bay as well. Vela Luka tide-gauge measurements reveal that high-frequency sea-level oscillations were strongest between 10:00 and 16:00 UTC of 14 May, and then again between 21:00 UTC of 15 May and 02:00 UTC of 16 May. On 14 May, maximum wave of 71.0 cm height was recorded between 14:48 and 15:02 UTC, and average period of dominant oscillations was 12-13 min. On 15 May, maximum wave of 80.3 cm was recorded between 22:50 and 23:03 UTC, and average period of dominant oscillations was 16-18 min. In spite of fact that sea-level oscillations were equal or even somewhat stronger than those observed three days earlier, air pressure data from both Vrboska and Vela Luka reveal much weaker air pressure disturbances reaching maximum heights of 1.4 hPa (both locations), and maximum 5-min rates of air pressure oscillations of -0.7 hPa\/5 min (Vrboska), i.e. -1.1 hPa\/5 min (Vela Luka). Nonetheless, the high-frequency air pressure oscillations were present through a better part of 14-15 May 2020. Both atmospheric and ocean component of the event were numerically modelled by\u00a0Toj\u010di\u0107 et al. (2021)<\/a>\u00a0with the meteotsunami module of real-time one-way coupled atmosphere-ocean AdriSC model.\u00a0<\/p>

Synoptic situation slightly differed from the situation during the\u00a0Event 32<\/a>\u00a0which occurred three days earlier.\u00a0Synoptic situation over Europe was now\u00a0<\/span>dominated by a low off the Portuguese coast\u00a0 with related weak mean sea level\u00a0<\/span>pressure gradients over the Mediterranean and the Adriatic Sea. Over\u00a0<\/span>the Adriatic Sea weak sirocco was blowing, reaching speeds from 10 to 16 m\/s.\u00a0<\/span>At the 850 hPa, a warm air mass was advancing from the\u00a0<\/span><\/span>central Sahara, across the central Mediterranean towards the Adriatic Sea. As a\u00a0<\/span>result, an upper-level temperature front was still well developed over the Adriatic Sea. At\u00a0<\/span>the 500 hPa height, strong south-westerly winds (up to 38 m\/s), related to a deep low, blew over\u00a0<\/span>the Adriatic.<\/span>\u00a0<\/span>\u00a0<\/span><\/p>
