Abstract
The formation and decay of geophysical eddies near the surface is one of the important physical problems. The evolution of such vortices is a complex phenomenon. Simplified hydrodynamic models of evolution of unsteady vortices allow a more detailed study of the main processes that
affect their emergence and development. One of the key parameters of such models is the profile of the initial vorticity. Our work presents the study of evolution and formation of the vortices near the solid surface for different initial vorticity profiles (Rankine, Burgers,
and Vatistas) aloft. By setting different profiles and heights of the initial vortices, we investigated the evolution of their main parameters. As a result, similarities and differences in their behavior were obtained.
