Seiche oscillations in the Nakhodka Gulf

详细

Spatiotemporal parameters of barotropic seiche oscillations in the Nakhodka Gulf in the Sea of Japan are considered using the spectral finite-difference model. The finite-difference approximation of shallow water equations is carried out at the irregular triangular spatial grid. The sets of periods and spatial structures of seiche oscillations corresponding to the strongly pronounced maxima of energy spectrum of sea level data from Nakhodka station of the Russian tsunami warning service are computed and presented.
