Analysis of water circulation on izmit bay under different meteorological conditions with mitgcm

Abstract

We used the MITgcm model with Orlanski boundary conditions and process-oriented modeling to examine the sensitivity of the Izmit Bay water circulation to wind speed, direction, and duration. The simulations demonstrated that there is little variation in seawater temperature, salinity, or stratification under modest forcing. Depending on the direction, substantial forcing at wind speeds of 4.9 m/s, 6.7 m/s, and 10.1 m/s produces notable and sub-mesoscale processes. Easterly component winds raises subsurface waters to the surface, whereas westerly component winds causes downwelling over the eastern shore. It is found that the hydrography of the bay is open to be largely impacted by extreme wind occurrences that exceeded 4.9 m/s.
