Prediction of Hydrophysical Fields in the Georgian Sector of the Black Sea and the Ways of Its Improvement

Abstract

Since 2010, a short-term regional marine forecasting system of hydrophysical fields – the current, temperature and salinity operates for the Georgian sector of the Black Sea and adjacent water area. This system, which is developed at M. Nodia Institute of Geophysics of Iv. Javakhishvili Tbilisi State University, is one of the parts of the Black Sea basin-scale Nowcasting/Forecasting System. The forecasting system is based on the regional model of Black Sea dynamics of M. Nodia Institute of Geophysics (RM-IG), which is nested in the basin-scale model of Black Sea dynamics of Marine Hydrophysical Institute (Sevastopol). 2D and 3D impurities dispersion models are coupled with RM-IG. Further development and improvement of the regional forecasting system is associated with the development of a very high-resolution forecasting subsystem for the coastal zone of Adjara-Poti-Anaklia (with a horizontal grid step 200-250 m) with the inclusion of a model of wind-induced surface waves in the subsystem.
