Analysis of effects of constant wind on the velocity of currents and seiche oscillations in the Azov Sea level

Abstract

Physical regularities of free oscillations of the Azov Sea level induced after the cessation of long-lasting action of wind are analyzed. Spatial characteristics of seiche oscillations, the position of nodal lines, and the velocity of induced currents are simulated with the three-dimensional nonlinear barotropic hydrodynamic model. It was found that in the coastal zone the maximum amplitude of these oscillations is comparable with the value of storm surges. It is demonstrated that seiches make essential contribution to the variability of velocity of currents.
