Simulation of the ice cover and thickness and water temperature of the Sea of Azov for the period 1920–2016 was done with using multi-compartment hydrological model which was modify to operate on a daily time step. Monitoring data from the coastal weather stations are model inputs. The simulation results were compared with values of ice cover and water temperature from MODIS (Terra and Aqua) satellite data for 2006–2016 and with observations of the ice thickness in the ports. It is shown that the model can be used for creating a historical reanalysis of the Sea of Azov ice cover, as well as for operational forecasting. Long-term dynamics (1920 to present) of the Sea of Azov ice cover and thickness average annual values is presented. Easing of ice conditions in the modern period was noted. Average ice extent of the Sea of Azov in the beginning of the XXI century is 16%, which is almost 2 times less than in the middle of the XX century. However according to the simulation results at the background of ice cover square and duration decreasing in the last decade the average ice thickness has been decreased not significantly.
Keywords: ice cover, Sea of Azov, mathematical models, processing satellite images of Terra/Aqua MODIS
