Elements of Physical Oceanography is a derivative of the Encyclopedia of Ocean Sciences, Second Edition and serves as an important reference on current physical oceanography knowledge and expertise in one convenient and accessible source. Its selection of articles—all written by experts in their field—focuses on ocean physics, air-sea transfers, waves, mixing, ice, and the processes of transfer of properties such as heat, salinity, momentum and dissolved gases, within and into the ocean. Elements of Physical Oceanography serves as an ideal reference for topical research. References related articles in physical oceanography to facilitate further research Richly illustrated with figures and tables that aid in understanding key concepts Includes an introductory overview and then explores each topic in detail, making it useful to experts and graduate-level researchers Topical arrangement makes it the perfect desk reference
This book was first published in 2005. When an oceanic tidal wave that is primarily active on the water surface passes an ocean shelf or a region with a seamount, it is split into a less energetic surface wave and other internal modes with different wavelengths and propagation speeds. This cascading process, from the barotropic tides to the baroclinic components, leads to the transformation of tidal energy into turbulence and heat, an important process for the dynamics of the lower ocean. Baroclinic Tides demonstrates the analytical and numerical methods used to study the generation and evolution of baroclinic tides and, by comparison with experiments and observational data, shows how to distinguish and interpret internal waves. Strongly non-linear solitary internal waves, which are generated by internal tidal waves at the final stage of their evolution, are investigated in detail. This book is intended for researchers and graduate students of physical oceanography, geophysical fluid dynamics and hydroacoustics.
An extension of a simplified, quasi-geostrophic, baroclinic theory of long waves set forth by Hess is presented. The ramifications of the stability aspects of the model and the results of adding a form of y-dependence to the system are examined. Finally, a steady state, adiabatic energy equation is added to the model as a diagnostic tool for specifying vertical profiles of the basic westerly current U (p) as a function of the parameters of the problems and as a function of particular vertical temperature profiles. Profiles U (p) for the model proposed by Hess are obtained and investigated as to their physical realism. The analogous profiles for the y-dependent case are not explicitly set forth due to mathematical difficulties. However, their general form is discussed in the light of the prior results of the investigation. (Author).
The normal mode equations for a two-layer ocean without current are scaled with characteristic distance, wind stress and time (or moving speed). When there is a geostrophic current in the upper layer, the normal mode separation is not possible, but equations for the barotropic transports include effects of the stationary current forcing terms as perturbation terms and the storm induced baroclinic transports as forcing functions. For a typical typhoon moving over the Kuroshio, the effects of the currents and the baroclinic transport become negligible for the barotropic transports which are determined by an iteration method. When the moving speed is less or more than about 5 m/sec, slow-moving or fast-moving approximation can be used. In the 1st case the interface shows almost uniform upwelling in a wake of the storm, and this is intensified slightly by the barotropic transports, particularly when the storm moves over the maximum current axis. In the 2nd case the interface shows undulated upwelling and effects of the barotropic transports become less than in the 1st case.
