The impact of surface currents and sea level on the wave field evolution during St. Jude storm in the eastern Baltic Sea

摘要: Summary A third generation numerical wave model SWAN (Simulating WAves Nearshore) was applied to study the spatio-temporal effect of surface currents and sea level height on significant height; describe mechanisms responsible for wave–current interaction in eastern Baltic Sea. Simulation results were validated by comparison with situ measurements deep shallow water, carried out using directional buoy RDCP respectively, TerraSAR-X imagery. hindcast period from 23 31 October 2013 included both a calm moderate weather conditions severe North-European windstorm called St. Jude. The prevailing wind directions southerly westerly. Four simulations made: control run dynamical forcing only; additional inputs level, separately combined. clear field evolution found. It manifested itself as an increase or decrease up 20%. strength influenced propagation waves severity conditions. An mostly seen shallower waters areas where propagating opposite directions. In deeper parts Sea case same direction occurred.
