The paper presents the results of numerical experiments comparing the difference schemes used in solving the problem for the current function. For comparative analysis, a model is proposed that takes into account fairly general wind situations and its analytical solutions are found. Comparison of numerical and analytical solutions is carried out in different grid norms. The comparative analysis carried out in this paper allows us to make a reasonable choice of a difference scheme for the numerical solution of such problems in complete models of sea hydrodynamics. This choice allows, all other things being equal, to increase the accuracy of the solution using less computing resources. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
