This book was released on 2013-03-07 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is an attempt to compile the present state of knowledge on ocean wave analysis and prediction. The emphasis of the monograph is on the development of ocean wave analysis and predic tion procedures and their utility for real-time operations and appli cations. Most of the material in the monograph is derived from journal articles, research reports and recent conference proceedings; some of the basic material is extracted from standard text books on physical oceanography and wind waves. Ocean wave analysis and prediction is becoming an important activity in the meteorological and oceanographic services of many countries. The present status of ocean wave prediction may be compar able to the status of numerical weather prediction of the mid-sixties and early seventies when a number of weather prediction models were developed for research purposes, many of which were later put into operational use by meteorological services of several countries. The increased emphasis on sea-state analysis and prediction has created a need for a ready reference material on various ocean wave analysis and modelling techniques and their utility. The present monograph is aimed at fulfilling this need. The monograph should prove useful to the ocean wave modelling community as well as to marine forecasters, coastal engineers and offshore technologists. The monograph could also be used for a senior undergraduate (or a first year graduate) level course in ocean wave modelling and marine meteorology.
Download or read book Directional Slope and Curvature Distributions of Wind Waves written by Jin Wu and published by . This book was released on 1975 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The slope and curvature distributions of wind waves along two principal axes (upwind-downwind and crosswind) have been measured in a laboratory tank under various wind velocities. In both directions, the slope distributions are very closely Gaussian, and the components of the mean-square water-surface slope vary logarithmically with the friction velocity of the wind. As the wind velocity increases, the ratio between these two components increases and falls between 0.5 and 0.6 at high wind velocities in the gravity-governing regime of wind-wave interaction. The radius of water-surface curvature, along either direction of measurement, is found to be, generally, greater at a steeper viewing angle from the normal to the mean water surface. The average radius of curvature of the disturbed surface varies inversely with the friction velocity of the wind. The ratio between the upwind-downwind and crosswind components of the average radius of curvature is unity at all wind velocities, indicating that the wind-disturbed water surface is isotropic on the smallest scale.

Download or read book Wind Over Waves written by S G Sajjadi and published by Elsevier. This book was released on 2003-07-01 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses ocean wave processes and turbulence as they affect oceanography, meteorology, marine and coastal engineering. It will enable applied mathematicians, seafarers, and all others affected by these phenomena to predict and control wave effects on shipping safety, weather forecasting, offshore structures, sediment pollution, and ice dynamics in polar regions. The focus is on analytical and computational methods for solving equations of motion and studying non-linear aspects of waves and turbulence. Results included show how sudden gusts and winds over waves can modify the mechanisms of wave-breaking and oceanic turbulence. The book records the proceedings of the Wind Over Waves conference of the Institute of Mathematics and its Applications at Churchill College, Cambridge. Co-sponsors with the IMA are the Institute of Civil Engineers and the Royal Meteorological Society.

Book excerpt: This report analyzes and reviews the processes involved in the generation of modulations in short wave structure by internal waves. The emphasis is on field conditions where, in general, there is wind blowing, a mean current with vertical structure, long and short waves at different directions to the internal wave and possibly surface films. The applicability or otherwise of theoretical analyses and laboratory experiments to field situations is discussed, the problem being the variety of interacting phenomena found under natural conditions. Chapter headings are the following: Mean velocity structure above the thermocline; The variations in surface velocity resulting from internal waves; Surface films; Energy modulations in a surface wave train produced by direct interaction; Wave breaking.
Download or read book The Interaction of Ocean Waves and Wind written by Peter Janssen and published by Cambridge University Press. This book was released on 2004-10-28 with total page 310 pages. 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.
Download or read book Correlation of Micro and Macroscopic Structures of Wind Waves and Differential Roughening and Smoothing of Surface Waves by Wind written by Jin Wu and published by . This book was released on 1973 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simultaneous measurements were conducted in a wind-wave tank of the ripple slopes with an optical instrument and of the carrier-wave profiles with a wave-height gage. The experiments were conducted under various wind CONDITIONS: either steady or unsteady wind blowing over pre-existing regular surface waves. The data were analyzed to determine the slope distributions of ripples located on various portions of the carrier-wave profiles under steady wind, and the differential roughening and smoothing of the carrier waves under unsteady wind. The influences of pre-existing waves on the structure of the wind boundary layer, and on the slope statistics of ripples were also studied.
