The object of the study is the diagnosis of the state of the marine environment and development of operational forecasts of variability of meteorological conditions over the sea area, oceanographic and environmental characteristics of the sea using methods of numerical mathematical modelling. The aim of the study is to improve and develop the national automated system of diagnosis and operational forecasting of short-term variability of oceanographic and environmental parameters of the marine environment in the Black and Azov Seas, which is based on the use of the latest generation numerical mathematical models. Research methods used in the study are numerical prognostic hydro-thermodynamic models of oceanographic processes in the marine environment, spectral model of wind waves, mesoscale prognostic model of meteorological conditions, standard statistical methods of information processing. The automated modelling complex for diagnosis and forecast of oceanographic characteristics in the Ukrainian part of the Azov-Black Sea basin water area, created in 2017-2019, was improved. The Delft3D-FLOW hydrodynamic block of the complex was replaced by a new generation numerical hydro-thermodynamic model Delft3D Flow Flexible Mesh. Adjustment of the modelling system to work on an unstructured computational mesh was performed. The results of numerical experiments carried out to verify the performance of the modernised integrated suite of models are presented. The water availability of the rivers Danube, Dniester, Dnieper, Southern Bug has been analysed. The mesoscale meteorological model WRF was configured to provide forecasts of meteorological conditions above the Black Sea. The results of the model test runs are presented.
