Sažetak
Meteorological tsunamis are sea level oscillations with periods similar to those of tsunamis, but are of meteorological origin and are usually caused by a traveling air pressure disturbance. Stari Grad on the island of Hvar is one of the most affected locations in the Adriatic Sea and it was the focus of this study. Numerical modeling was done using SCHISM (Semi-implicit Cross-scale Hydroscience Integrated System Model), which is based on unstructured grids. The model domain encompassed the entire Adriatic Sea, and meteorological forcing had the shape of a boxcar function travelling in an eastward direction. The results indicated that Proudman resonance takes place in the open Adriatic for velocities of the air pressure disturbance exceeding 26 m/s whereas the bay's funnel shape causes amplification for all velocities. The ratio of wave height inside and in front of the bay for different velocities and durations of the disturbance suggested the possibility of resonance and damping taking place in the bay.
