Historical Model data

Near-operational system of Black sea circulation is based on the primitive equation model of the Black Sea circulation with 5 km grid step (www.arena-blacksea.net). External forces are provided by ALADIN atmospheric model. An important part of the near-operational system is assimilation of space remote sensing data including sea surface anomalies, provided in a near real time mode by AVISO/Altimetry a multi-satellite data active archive center dedicated to space oceanography (France) and surface temperature (via direct acquisition of Advanced Very High Resolution Radiometer (AVHRR)). The output of the system is time series of three dimensional hydrophysical fields (temperature, salinity, current velocities).

SST and surface velocities model output

Since September 2007 the experimental near-operational data for surface waves height and direction and 48h forecast are including in near-operational nowcasting/forecasting system of Black sea hydrophysical fields. These data are calculated on the base of WAM model.
External forces are provided by ALADIN atmospheric model. An important part of the prediction procedure is assimilation of the current velocities on 5 m depth for wave-current refraction effect calculation from MHI Black Sea circulation model.

Wave height and direction model output
