Book Description
An annular, stratified flow tank was designed and built to study gravity wave, mean flow (critical layer) interactions. The tank contained stratified salt water, and an initial shear profile was generated by blowing air over the water surface. Internal gravity waves were generated by displacing the bottom floor of the tank in a known way. A preliminary critical layer experiment was performed to prove the feasibility of studying critical layer interactions in the experimental facility. Quantitative measurements of mean flow velocities, velocity perturbations, and vertical wavelengths were obtained. Keywords: Critical layers; Stratified; Shear Flow; Gravity waves.

Book Description
The study of internal gravity waves provides many challenges: they move along interfaces as well as in fully three-dimensional space, at relatively fast temporal and small spatial scales, making them difficult to observe and resolve in weather and climate models. Solving the equations describing their evolution poses various mathematical challenges associated with singular boundary value problems and large amplitude dynamics. This book provides the first comprehensive treatment of the theory for small and large amplitude internal gravity waves. Over 120 schematics, numerical simulations and laboratory images illustrate the theory and mathematical techniques, and 130 exercises enable the reader to apply their understanding of the theory. This is an invaluable single resource for academic researchers and graduate students studying the motion of waves within the atmosphere and ocean, and also mathematicians, physicists and engineers interested in the properties of propagating, growing and breaking waves.

Book Description
Laboratory observations of gravity wave, critical layer experiments are presented. In the experiments, a stratified shear flow is generated, and internal gravity waves are allowed to propagate into the flow. The waves propagate up to, but no farther than, their critical layer, the depth where the mean flow equals the horizontal phase speed of the wave. Results are presented with one and two internal waves propagating into the flow. Measurements include mean density and velocity profiles, instantaneous density and velocity profiles, shadowgraph observations, Digital Particle Imaging Velocimetry, and Richardson number estimates. The results show that early wavebreaking is Kelvin Helmholtz. Later wavebreaking is characterized by internal mixing regions. With the two wave forcing, the observed late time turbulence is correlated with the internal wave amplitude.

Book Description
This monograph creates a systematic interpretation of the theoretical and the most actual experimental aspects of the internal wave dynamics in the ocean. Firstly, it draws attention to the important physical effects from an oceanographical point of view which are presented in mathematical descriptions. Secondly, the book serves as an introduction to the range of modern ideas and the methods in the study of wave processes in dispersive media. The book is meant for specialists in physics of the ocean, oceanography, geophysics, hydroacoustics.
