Book excerpt: The microstructure of the wind-disturbed water surface, characterized by surface-slope and surface-curvature distributions is studied with a newly-developed optical instrument. The measurements show systematically some features of these distributions under various wind conditions, and are correlated with the results of airflow boundary-layer surveys. Two regimes of equilibrium with different mechanisms for limiting wave growth are also discussed. In addition, with a turbulent wind, the present laboratory results exhibit variation of the mean square slope with the shear velocity similar to older oceanic data, suggesting possibility of the laboratory simulation of the microstructure of the air-sea interface.

Download or read book Wind Generated Ocean Waves written by I.R. Young and published by Elsevier. This book was released on 1999-03-23 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goals of wind wave research are relatively well defined: to be able to predict the wind wave field and its effect on the environment. That environment could be natural (beaches, the atmosphere etc.) or imposed by human endeavour (ports, harbours, coastal settlements etc.). Although the goals are similar, the specific requirements of these various fields differ considerably. This book attempts to summarise the current state of this knowledge and to place this understanding into a common frame work. It attempts to take a balanced approach between the pragmatic engineering view of requiring a short term result and the scientific quest for detailed understanding. Thus, it attempts to provide a rigorous description of the physical processes involved as well as practical predictive tools.
Download or read book Wind Waves in Oceans written by Igor Lavrenov and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of sea waves has always been in the focus of mankind's atten tion. This is attributed not only to a desire to understand the behaviour in seas and oceans, but also, it has some practical necessity. Developing up-to date wind wave numerical methods requires detailed mathematical modelling, starting with wave generation, development, propagation and transformation on the surface in different water areas under quasi-stationary conditions, up to a synthesis of climatic features observed under different wave generation conditions in oceans, sea or coastal areas. The present monograph considers wind waves in terms of the most general formulation of the problem as a probable hydrodynamic process with wide spatial variability. It ranges between the global scale of the oceans, whose typical size is comparable with the Earth's radius, to the regional and local scales of the seas, including water areas limited in space with significant current or depth gradients in coastal zones, where waves cease their existence having propagated tens of thousand miles.
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 Wind Waves written by Blair Kinsman and published by Courier Corporation. This book was released on 1984-01-01 with total page 706 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this classic study, a renowned student of ocean wave theory examines the data requirements and details of the power spectral analysis required to make the wave revolution intelligible. Although the discussions center on waves, once the techniques are understood, they can be applied to many other areas. After outlining the nature of waves and wave processes and their methods of measurement and classification, the author provides a detailed exploration that relies heavily on mathematical models. Topics include perturbations of irrotational motion, energy considerations, wave generations by wind, and much more. The text is enhanced and clarified by 270 photos, figures, and tables. A helpful bibliography and indexes conclude this indispensable addition to the oceanographer's library.
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 Operational Analysis and Prediction of Ocean Wind Waves written by Madhav L. Khandekar and published by Springer Science & Business Media. 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.

This book was released on 2015-04-03 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an update of the first BACC assessment, published in 2008. It offers new and updated scientific findings in regional climate research for the Baltic Sea basin. These include climate changes since the last glaciation (approx. 12,000 years ago), changes in the recent past (the last 200 years), climate projections up until 2100 using state-of-the-art regional climate models and an assessment of climate-change impacts on terrestrial, freshwater and marine ecosystems. There are dedicated new chapters on sea-level rise, coastal erosion and impacts on urban areas. A new set of chapters deals with possible causes of regional climate change along with the global effects of increased greenhouse gas concentrations, namely atmospheric aerosols and land-cover change. The evidence collected and presented in this book shows that the regional climate has already started to change and this is expected to continue. Projections of potential future climates show that the region will probably become considerably warmer and wetter in some parts, but dryer in others. Terrestrial and aquatic ecosystems have already shown adjustments to increased temperatures and are expected to undergo further changes in the near future. The BACC II Author Team consists of 141 scientists from 12 countries, covering various disciplines related to climate research and related impacts. BACC II is a project of the Baltic Earth research network and contributes to the World Climate Research Programme.
Download or read book Field Studies of Run up Generated by Wind Waves on Dissipative Beaches written by Christopher Turner Carlson and published by . This book was released on 1984 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field measurements of incident waves and the resulting run-up made at two different natural sand beaches along San Francisco Bay show low-frequency energy in the run-up not observed in the corresponding incident-wave spectra. The experiments were conducted in December 1977 at Alameda Beach and in May 1982 at Coyote Point Beach. Both experiments were designed to measure the run-up on dissipative beaches exposed only to high-frequency, narrow-band wind waves at the exclusion of lower frequency swell. Criteria for field-site selection included a single breaker zone located near the shoreline with incident wind waves that broke by plunging, thereby minimizing reflection and forming a low-energy dissipative beach system. Elimination of the long-wave components in the incident wave field would suppress reflection at the shoreline, minimizing external nonlinear modulation of the run-up by edge waves and standing waves. Amplitude time series measurements of offshore incident waves and the run-up on the beach face were made simultaneously at multiple locations on the beach using 16-mm photography. Coherence analyses indicate that the offshore incident waves and run-up on the beach are not linearly correlated. Correlation analyses conducted on the run-up at alongshore distances up to 3.5 m indicate that the run-up is coherent in the alongshore direction up to this distance.
