Abstract (english)
Surface wind wave dynamics were analyzed during wind transition from the third to the fourth quadrant, with the transition from Sirocco to Libeccio used as an example. This research is focused on the deepwater area in front of the Rijeka port. The analyses utilized a numerical model for wave generation, covering the entire Adriatic basin. Numerical simulations were conducted for relevant situations during the period 1998-2001. The numerical model was forced by the wind field obtained from the Aladin-HR atmospheric model. Numerical simulations were conducted in two steps, initially using hypothetical scenarios with homogenous and stationary wind fields, followed by simulations based on nonstationary wind fields from the Aladin-HR atmospheric model. The first step was used to confirm the hypothesis that significant wave heights rise during the transition of wind direction in the analyzed area. Model simulations in step two verified the assumption that the observed phenomenon can also occur in real atmospheric conditions.The results of the model simulations indicate the onset of a significant wave height increase during the transition of wind direction from the SSE to SW in a wider area that includes Kvarner and Rijeka bay. The increase in wind velocity results in a more noticeable significant wave height maximum.
Abstract (croatian)
Analizirana je dinamika valnih visina tijekom tranzicije smjera vjetra iz trećeg u četvrti kvadrant, poglavito juga u lebić. Područje istraživanja fokusirano je na dubokovodno područje ispred luke Rijeka. U analizama je primijenjen numerički model valnog generiranja s obuhvatom cijelog jadranskog bazena. Numeričke simulacije su provedene za relevantne situacije tijekom razdoblja 1998. - 2001. godine. Numerički model je forsiran poljem vjetra dobivenim iz atmosferskog modela Aladin/HR. Numeričke simulacije provedene su u dva koraka, inicijalno korištenjem hipotetskih scenarija s djelovanjem homogenog i stacionarnog polja vjetra te nastavno primjenom nestacionarnog polja vjetra iz atmosferskog modela Aladin/Hr. Prvom koraku istraživanja cilj je potvrditi hipoteze o rastu izrazitih valnih visina tijekom tranzicije smjera vjetra u analiziranom području. Modelske simulacije u drugom koraku potvrđuju pretpostavku da uočena fenomenologija može nastupiti i u realnim atmosferskim uvjetima. Rezultati modelskih simulacija ukazuju na pojavu ekstrema HS u situacijama kada tranzicija smjera vjetra iz JJI u JZ nastupa u širem području koje uključuje i Kvarner i riječki zaljev. Veća brzina vjetra rezultira izraženijim ekstremom Hs.
