Numerical simulation of an intensive upwelling event in the northeastern part of the Black Sea at the IO RAS hydrophysical testing site

Аннотация

The paper discusses mathematical simulation of intensive coastal upwelling observed in the northeastern part of the Black Sea in the water area of the hydrophysical test site of the Shirshov Institute of Oceanology, Russian Academy of Sciences, in September 2013. The simulation was carried out with the MIKE 21/3 Coupled Model FM combined hydrodynamic model of the Danish Hydraulics Institute (DHI). The calculation results are compared with the data of direct instrumental observations carried out in the IO RAS hydrophysical survey area. The essential role of surface wind waves in the formation of the observed temperature profiles is demonstrated, as well as the necessity of taking it into account when considering peculiarities in the vertical circulation of coastal waters.
