Computational aspects of calculating the vertical velocity component in a hydrodynamic model
The paper considers a method for calculating the vertical velocity component in a dynamic model based on the run-through algorithm. The procedure is based on differentiating the continuity equation by the vertical coordinate and solving the resulting equation taking into account both boundary conditions, at the bottom and at the surface. The use of such a procedure allows us to obtain a certain increase in the kinetic energy, the vertical component of vorticity, and especially the maximum velocities due to the lack of circuit viscosity when approximating the second-order derivative vertically.
