Abstract Accurate predictions of surface ocean waves in coastal areas are important for a number marine activities. In complex coastlines with islands and fjords, the quality wind forcing significantly affects results. We investigate role on wave conditions fjord system partly exposed to open sea. For this reason, we implemented model SWAN at west coast Norway using four different forcing. Wind estimates were compared observations from five measurement sites. The best results terms...

Abstract In slanting fetch conditions the direction of actively growing waves is strongly controlled by geometry. The effect was found to be pronounced in long and narrow Gulf Finland Baltic Sea, where it significantly modifies directional wave climate. Three models with different assumptions on coupling between components were used analyze physics responsible for behavior gulf. directionally decoupled model produced at spectral peak correctly when geometry but gave a weaker steering than...

Abstract. This paper presents how to account for the lack of sampling variability in model data when they are combined with wave measurements. We addressed dissimilarities between types by either (i) low-pass filtering observations or (ii) adding synthetic model.

Interactions of sea surface waves and ocean circulation are traditionally modeled using simplified parameterizations, often based on global data. More refined estimates wave-ocean interactions hydrodynamics can be achieved through coupled models with both wave components. When moving from implicit parameterizations to explicit formulations, reevaluation the governing momentum energy transfer as well vertical mixing turbulence is inevitable. This particularly...

Abstract. A significant wave height of 7 m has been measured five times by the northern Baltic Proper buoy in Sea, exceeding 8 twice (2004 and 2017). We classified these storms into two groups duration steepness. Interestingly, highest events exhibited opposite properties, with 2017 event being longest storm on record. This is also first where harshest conditions were modelled to occur western part Proper. The metrics quantifying storm's steepness might aid issuing warnings for extreme conditions.

The seasonal ice cover has significant effect on the wave climate of Baltic Sea. We used third-generation model WAM to simulate Sea field during four seasons (2009†-2012). data from two different sources: daily charts compiled by FMI's Ice Service and modeled mean concentration SMHI's NEMO†Nordic model. utilized methods: a fixed threshold 30 % concentration, after which energy is set zero, grid obstruction method up 70 zero. simulations run using chart had slightly better accuracy than...

WAM, SWAN and WAVEWATCH III® were implemented to the Finnish archipelago with a 0.1 nmi grid. A comparison coastal wave buoy observations showed that models agreed on significant height, biases root-mean-square-errors (RMSE) differing at most 0.06 m. In general sense, WAM propagated long energy into archipelago, while generated highest local waves. The performance of III was wind direction dependent. model tendencies caused them disagree peak period near coast, differences in mean values...
