“…This model successfully simulates the parameters of wind waves in the open sea and coastal areas [Akpinar et al, 2012;Akpinar and Ponce de León, 2016;Arkhipkin et al, 2014;Lopatuhin et al, 2006;Medvedeva et al, 2015;Myslenkov and Arkhipkin, 2013]. It is important that the SWAN model successfully simulates sea waves in the shallow water as well because depth of Tsemes Bay essentially varies between 20 and 40 m.…”

“…This is default configuration for SWAN model and we used it because we have successful wave modelling with this settings [Arkhipkin et al, 2014;Arhipkin et al, 2015;Medvedeva et al, 2015;Myslenkov and Arkhipkin, 2013;Myslenkov et al, 2016;Stoliarova and Myslenkov, 2015;Toropov et al, 2012] and we had no physical justification for changing any of the coefficients. Scientists have used this model in several investigation and its detailed description and technical summary are present in publications [Akpinar et al, 2012;Akpinar and Ponce de León, 2016;Booij et al, 1999;SWAN Team, 2007;Van Vledder and Akpinar, 2015].…”

“…However, there are few quality estimates of the model presented in this paper. There are several publications giving more detailed model quality estimation based on direct wave measurements provided by the NATO TU-WAVES project [Akpinar et al, 2012;Akpinar and Ponce de León, 2016;Kos'yan et al, 1998;Van Vledder and Akpinar, 2015]. In work [Akpinar et al, 2012] the results of SWAN model are based on the Era-interim reanalysis.…”

“…Comparison of model results and wave buoy measurements has shown that the model under-estimates wave height values. In the works [Akpinar and Ponce de León, 2016;Van Vledder and Akpinar, 2015] different reanalysis were compared, while the main conclusion was that the NCEP/CFSR reanalysis provided better result (the root mean square error (RMSE) -0.4 and correlation -0.88). Comparison of the significant wave height (SWH) and satellite data resulted in RMSE and correlation equalling 0.4 and 0.78 respectively.…”

The results of wave simulation in the Black Sea using the SWAN spectral wave model and wind forcing data from the NCEP/CFSR reanalyze are presented in this paper. The calculations were done using the special unstructured mesh with spatial resolution of 10 km in the open sea and 200 m in the Tsemes Bay. The assessment of the wave simulation accuracy was performed on the basis of the satellite altimetry data and direct wave measurements in the shallow water. When comparing the calculated significant wave height with observational data the correlation equaled 0.8, while the root mean square error equaled 0.3. The comparison of simulation results and satellite data also showed good correlation. KEYWORDS: Black Sea; Tsemes Bay; wind waves; wave modeling; SWAN; unstructured mesh; satellite altimetry.

This study evaluates the performance of a dynamic ensemble of wave climate simulations for the Black Sea. The ensemble members (and ensemble means) are evaluated for the historical period . The spectral wave model (simulating waves nearshore [SWAN]) was forced with eight Coupled Model Intercomparison Project Phase 5 (CMIP5) based Regional Climate Models (RCMs) wind fields to obtain each of the eight ensemble members. The RCMforcings used belongs to the European branch of the Coordinated Regional Downscaling Experiment (EURO-CORDEX). The ensemble members' historical wave climate is thoroughly compared against the ERA5 reanalysis, in situ observations, and altimeter measurements. In addition to the individual evaluation of ensemble members, the results for the 8-member ensemble mean are also examined. The performance of the ensemble members in reproducing the mean and extreme significant wave heights, mean wave periods, and mean wave directions is found to be good, with differences generally between +25 and −15% in comparison to ERA5. Differences between +10% and −30% were found for the comparison with altimeter measurements. We conclude that the ensemble better represents the wave climate of the Black Sea, than its individual members. The 8-member ensemble provides a more balanced dataset for the Black Sea wave climate and a better representation of the associated uncertainty. Thus, further wave climate projections for the Black Sea should rely on the use of an ensemble.

Wave phenomena impact high commercial value coastal and offshore activities, infrastructures and transportation. The knowledge of future wave conditions allows for consistent long‐term planning and decision‐making. The present study aims to provide robust, reliable projections of the potential future wave conditions of the Black Sea under the influence of climate change. For this purpose, an eight‐member dynamic wave climate ensemble that accurately represents the Black Sea's present wave climate has been produced, and future projections are assessed and analysed here. The wave climate ensemble was obtained by forcing the Simulating Waves Nearshore spectral wave model with eight regional wind fields from the EURO‐CORDEX. The future simulations of the regional wind fields are based on the RCP8.5 high‐emission scenario. The historical wave climate of the ensemble was evaluated against ERA5 reanalysis data. Projected changes in the mean wind and wave characteristics are examined by comparing historical and future simulations. In addition, the projected trends in the annual means during the future period of the wave simulations for significant wave height (Hs) and wave energy flux are also analysed. The projections for Hs and wind speeds are pronounced with significant decreases down to −10% across the basin, especially in the eastern region of the Black Sea. Changes in the Hs 99% percentiles of up to 16% are projected to occur. The projected changes in the annual mean of the wave energy flux are close to the projected changes in Hs means, while the seasonal changes (between −15% and 12%) are expected to be higher.
