The wind and wave climate over the Black Sea were investigated by providing extensive datasets covering the last 40 years (1979-2018). Wind characteristics over the Black Sea were evaluated by using two well-known wind fields (i.e., ECMWF ERA-Interim and NCEP/CFSR). Wave simulations were generated from the MIKE 21 SW model forcing with two wind datasets. The possible effect of the long-term variability on the wind and wave characteristics over the Black Sea was discussed in the context of climate change.

The aim of the present work is to assess the wind and wave climate in the Black Sea while considering various data sources. A special attention is given to the areas with higher navigation traffic. Thus, the results are analyzed for the sites located close to the main harbors and also along the major trading routes. The wind conditions were evaluated considering two different data sets, the reanalysis data provided by NCEP-CFSR (U.S. National Centers for Environmental Prediction-Climate Forecast System Reanalysis) and the hindcast results given by a Regional Climate Model (RCM) that were retrieved from EURO-CORDEX (European Domain-Coordinated Regional Climate Downscaling Experiment). For the waves, there were considered the results coming from simulations with the SWAN (Simulating Wave Nearshore) model, forced with the above-mentioned two different wind fields. Based on these results, it can be mentioned that the offshore sites seem to show the best correlation between the two datasets for both wind and waves. As regards the nearshore sites, there is a good agreement between the average values of the wind data that are provided by the different datasets, except for the points located in the southern part of the Black Sea. The same trends noticed for the average values remain also valid for the extreme values. Finally, it can be concluded that the results obtained in this study are useful for the evaluation of the wind and wave climate in the Black Sea. Also, they give a more comprehensive picture on how well the wind field provided by the Regional Climate Model, and the wave model forced with this wind, can represent the features of a complex marine environment as the Black Sea is.

The Impact

The objective of this study is to assess the future wind power potential in the Black Sea based on the wind fields provided by the most recent regional climate projections achieved in the framework of EURO-CORDEX project. The climate change impacts on the wind speed magnitude will bring changes in the local wind power generation. From this perspective, changes in the wind power potential along the 21st century in some reference locations of the Black Sea basin are investigated under the RCP4.5 scenario. The recent wind power conditions for a 30-year period (1976-2005) are assessed based on the results provided by the same RCM (Regional Climate Model) used to generate the future climate projections of the wind fields. The impact of the climate change on the future wind power potential is evaluated by comparisons between historical data and near-future (2021-2050) and more distant future (2071-2100) projections. Under the scenario considered, an increase of the mean wind power was observed until the middle of the 21st century, followed by a small decrease. From the seasonal analysis resulted that, in the reference points located on the western side, the projection of the wind energy in winter time suggests an increase until the end of the century. On the other hand, the linear regressions adjusted to the annual means do not indicate a significant trend.

The knowledge of the wave climate is one of the most important data for application of coastal engineering, which includes coastal structure design, sediment transport, coastal erosion and so on. Due to the lack of measurements in many region and high cost of wave measurements, coastal engineers have to estimate wave characteristics using a variety of methods, which comprise empirical and numerical solutions. A variety of empirical and numerical methods have been developed and used for determining wave characteristics. In this study, in order to determine wave climate over the Black Sea, it was used third generation Mike 21 spectral wave model. For this purpose, a series of numerical models were conducted in a way to cover the 13-year period between 1996 and 2008. The obtained results from numerical models were compared to the results of Wind and Deep Water Wave Atlas for Turkish Coasts. It was concluded that the results were highly consistent each other.
