Black Sea Waves Reanalysis (CMEMS BLK-Wave, EAS4 system)

The wave reanalysis for the Black Sea is produced with the third generation spectral wave model WAM Cycle 6. The reanalysis is produced on the HPC at Helmholtz-Zentrum Hereon and is continuously updated every six months, covering the period since January 1979. The shallow water Black Sea version is implemented on a spherical grid with a spatial resolution of about 2.5 km (1/40° x 1/40°) with 24 directional and 30 frequency bins. The number of active wave model grid points is 74518. The model takes into account wave breaking and assimilation of satellite wave and wind data. The system provides one-hourly output and the atmospheric forcing is taken from ECMWF ERA5 data.

本黑海海浪再分析数据集基于第三代频谱海浪模型WAM Cycle 6生成。该再分析数据集由亥姆霍兹-赫伦研究中心（Helmholtz-Zentrum Hereon）的高性能计算集群（High Performance Computing，HPC）生成，每半年持续更新一次，时间覆盖范围自1979年1月起至今。其浅海黑海版本采用球面网格，空间分辨率约为2.5 km（1/40°×1/40°），设置有24个方向分档与30个频率分档。有效海浪模型网格点总数为74518个。该模型兼顾海浪破碎过程模拟，并完成了卫星海浪与风场数据的同化处理。本系统输出时间间隔为1小时，大气强迫场数据取自欧洲中期天气预报中心（European Centre for Medium-Range Weather Forecasts，ECMWF）的ERA5数据集。
