目前工作的目的是评估风和波的气候在黑海，同时考虑到各种数据来源。特别注意导航交通量较高的区域。因此，分析结果的网站位于靠近主要港口，也沿着主要贸易路线。考虑到两个不同的数据集，NCEP-CFSR（美国国家环境预测-气候预报系统再分析中心）提供的再分析数据和区域气候模式（RCM）提供的后报结果，这些数据来自EURO-CORDEX（欧洲区域协调区域气候降尺度试验）。对于波浪，考虑了来自SWAN（模拟波浪近岸）模型的模拟结果，并受上述两种不同风场的影响。基于这些结果，可以提到的是，海上站点似乎显示出风和波浪的两个数据集之间的最佳相关性。至于近岸站点，除了位于黑海南部的点之外，不同数据集提供的风数据平均值之间有很好的一致性。平均值的趋势同样适用于极值。最后，可以得出结论，在这项研究中获得的结果是有用的风和波气候在黑海的评价。此外，它们还更全面地说明了区域气候模型提供的风场以及受这种风影响的波浪模型如何能够代表黑海这样复杂的海洋环境的特征。
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.
