Abstract

© 2022, Central Fisheries Research Inst. All rights reserved.Different upwelling index calculations used for oceans were tested by applying to the Aegean Sea and compared with each other. The sea surface temperature (SST) and wind data of ECMWF Reanalysis are used for upwelling index calculations. The decrease in SST is a result of upwelling; however, the parameter that lies behind the phenomenon is the wind stress on the sea surface. The results show that SST and wind-driven upwelling indexes could be roughly used to estimate upwelling phenomena in the Aegean Sea, but it is insufficient for the precise determination of upwelling due to the Aegean Sea’s unique dynamics. To reach a final formula, the "new upwelling index" shall be improved for Aegean Sea in which current data are considered besides SST & wind data.
