Black Sea Mixed Layer Sensitivity to Various Wind and Thermal Forcing Products on Climatological Time Scales

Abstract

This study describes atmospheric forcing parameters constructed from different global climatologies, applied to the Black Sea, and investigates the sensitivity of HYbrid Coordinate Ocean Model (HYCOM) simulations to these products. Significant discussion is devoted to construction of these parameters before using them in the eddy-resolving HYCOM simulations. Eight wind forcing products are used: four obtained from observation on the QuikSCAT satellite, and the rest formed from operational model products. Atmospherically-forced model simulations with no assimilation of any ocean data suggest that the basin-averaged RMS SST differences with respect to the Pathfinder SST climatology can vary from 1.21 degrees C to 2.15 degrees C depending on the wind and thermal forcing product. These are large variations in the annual mean surface circulation similated using the different wind sets.
