Purpose. The article is purposed at studying climatic fluctuations of the Azov Sea level on the scales of mesoscale and synoptic variability. Methods and Results. Hourly sea level rises in 1979-2020 obtained by the methods of numerical modeling using the coupled hydrodynamic (ADCIRC) and wave (MIKE 21 SW) models constitute the initial data for the analysis. The basic harmonics of sea level oscillations in the ranges of mesoscale and synoptic variability were determined, and spatial and seasonal characteristics of the oscillations were assessed. Conclusions. Main sea level oscillations in the ranges of synoptic and mesoscale variability are concentrated in the following periods (within a day): 0.5; 1; 1.8-2.5; 3-5; 5.5-7; 8.5-11; 12.5-13.5; 14.5-17. Sea level fluctuations with the periods exceeding two days have a form of a uninodal seiche whose amplitude maxima are in the coastal zone of two opposite areas: in the southwest of the sea (along the Arabat Spit) and in the northeast region (from the Yasenskaya to the Belosarayskaya spits)...
