Abstract
A boundary value problem is solved for the equations of motion, continuity, density constituents and turbulence characteristics in the 3D-domain of the northern Kuril Straits with boundary conditions determined by the solution of the global model. The boundary value problem is implemented by the finite volume method on an unstructured mesh in the hydrostatic approximation. Detailed tidal modelling of the Fourth Strait dynamics is performed in a non-hydrostatic approach. The results represent the velocity fields, residual circulation of the М2 tidal wave and the summary tide of eight harmonics M2, S2, N2, K2, K1, О1, P1, Q1 with a synodic period of 29.5 days. A comparison of the behaviour of the vertical velocity in the tidal cycle of the М2 wave for two subregions of the Fourth Strait when solving the boundary value problem in the Hs and the Nh approximation was performed. The Hoffmüller diagram of the dynamic characteristics in the synodic month is presented. It has been shown that taking into account the Nh approach, there is a significant change in the transfer of water masses through the Fourth Strait of the Kuril Ridge.
