Available in PDF, EPUB and Kindle. Book excerpt: This book was published in 2004. The Interaction of Ocean Waves and Wind describes in detail the two-way interaction between wind and ocean waves and shows how ocean waves affect weather forecasting on timescales of 5 to 90 days. Winds generate ocean waves, but at the same time airflow is modified due to the loss of energy and momentum to the waves; thus, momentum loss from the atmosphere to the ocean depends on the state of the waves. This volume discusses ocean wave evolution according to the energy balance equation. An extensive overview of nonlinear transfer is given, and as a by-product the role of four-wave interactions in the generation of extreme events, such as freak waves, is discussed. Effects on ocean circulation are described. Coupled ocean-wave, atmosphere modelling gives improved weather and wave forecasts. This volume will interest ocean wave modellers, physicists and applied mathematicians, and engineers interested in shipping and coastal protection.

This book was released on 1975 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical description is given of the behaviour of a broadband, small-amplitude wind-wave field to a perturbing internal wave velocity pattern. The theory includes the effect of the local wind. Specific predictions are made for the case of weak internal wave currents, and these predictions are compared to measurements. The theory predicts the magnitude of the mean-square-slope changes reasonably well, and it predicts the quadrant of the phases correctly. General features of the perturbed surface-wave energy spectrum integrated in an angle are also predicted reasonbly well, and comparisons are made of the theoretical and measured local integrated spectrum at roughened areas and at slick areas. Various conditions for two theoretical wind-wave spectra are used to predict the sensitivity (or magnitude of mean-square-slope change per unit-current change, suitably normalized) and phase of the slope field as functions of the wind. Representative calculations are also made to provide sensitivity and phase of mean-square height and mean-square curvature as functions of the wind. It is shown that the 'weak internal wave' analysis leads to a singular perturbation series, and a method for obtaining a uniformly valid expansion is given and explored in detail.

Download or read book Internal Gravity Waves written by Bruce R. Sutherland and published by Cambridge University Press. This book was released on 2010-09-02 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Oceanographic Applications of Remote Sensing written by Motoyoshi Ikeda and published by CRC Press. This book was released on 1995-09-18 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceanographic Applications of Remote Sensing describes how remotely sensed data fields can be applied to help solve problems in ocean-related studies. This timely reference, written by and for oceanographers, emphasizes the application of data to particular physical, chemical, and biological processes related to the ocean and the ocean-atmosphere system. The organization of the book reflects this emphasis, with chapters arranged by process rather than by sensor characteristics. Oceanographic Applications of Remote Sensing contains comprehensive information on the application of such relevant data sets as sea surface temperature and topography, ocean circulation, sea level variability, wind speed and stress, wave height, solar radiation flux at ocean surfaces, and sea-ice characteristics and ice motion. It also discusses the reliability of remotely sensed data and provides information about the applicability of the various data sets to particular process studies. Its completeness and relevance makes Oceanographic Applications of Remote Sensing an important reference for modern studies of ocean and coupled ocean-atmosphere processes. Its unique coverage of the physics that govern satellite processes and their applications to oceanography ensures that it will remain an important reference as new satellites are introduced.

Download or read book Waves in Oceanic and Coastal Waters written by Leo H. Holthuijsen and published by Cambridge University Press. This book was released on 2010-02-04 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waves in Oceanic and Coastal Waters describes the observation, analysis and prediction of wind-generated waves in the open ocean, in shelf seas, and in coastal regions with islands, channels, tidal flats and inlets, estuaries, fjords and lagoons. Most of this richly illustrated book is devoted to the physical aspects of waves. After introducing observation techniques for waves, both at sea and from space, the book defines the parameters that characterise waves. Using basic statistical and physical concepts, the author discusses the prediction of waves in oceanic and coastal waters, first in terms of generalised observations, and then in terms of the more theoretical framework of the spectral energy balance. He gives the results of established theories and also the direction in which research is developing. The book ends with a description of SWAN (Simulating Waves Nearshore), the preferred computer model of the engineering community for predicting waves in coastal waters.

Download or read book Interaction of Waves and Currents written by D. Howell Peregrine and published by . This book was released on 1983 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents an overview of wave-current interacion, including comprehensive review of references to significant U.S. and foreign literature available through December 1981. Specific topics under review are the effects of horizontally and vertically varying currents on waves, wave refraction by currents, dissipation and turbulence, small- and medium-scale currents, caustics and focusing, and wave breaking. The results of the review are then examined for engineering applications. The most appropriate general-purpose computer program to include wave-current interaction is the Dutch Rijkswaterstaat program CREDIZ, which is based on a parabolic wave equation. Further applications include wave and current forces on structures and possibly sediment transport. The report concludes with a brief state-of-the-art review of wave-current interaction and a list of topics needing further research and development.
