The results of comparing the model fields of 137Cs concentration in the Black Sea and the data of observations after the Chernobyl accident are presented. Several radiological surveys were used, during which 137Cs concentrations in the upper sea layer were measured for a year after the accident. Simulation of evolution of the caesium concentration field is performed taking into account atmospheric precipitation. A power function of time is proposed to describe the change in the radionuclide flux from the atmosphere. It was found that there is good compliance between observations and the results of calculations (the discrepancy is less than 30%) concerning the Black Sea Rim Current and the Western Cyclonic Gyre. The maximum differences occur in the areas of anticyclonic vortices. The 137Cs stock in the Black sea was estimated for the period from 1986 to 1991. It is shown that the total content of radioactive caesium corresponds to real data according to the calculation results.
