L. Hydrometeoizdat, 1991. The main provisions of the dynamic theory of tides are presented . Separate chapters are devoted to the discussion of the methods and results of experimental studies (including satellite measurements) , Qualitative study of tidal dynamics equations , the solution of the spectral problem for the World Ocean of real outlines , reconstruction of forced tides in the modern ocean and in the paleocean, parameterization of shelf and island effects and global interaction of ocean, Earth and Atmospheric Tides . Special attention is paid to the energy of ocean tides and their role in the tidal evolution of the Earth-Moon system. The results of laboratory, full-scale and theoretical studies of the vertical structure of the bottom boundary layer in the tidal flow are summarized . The book is addressed to specialists in ocean dynamics and Earth physics, hydrodynamics and mathematicians interested in problems: geophysics, and students of universities and hydrometeorological institutes of relevant specialties.
