The characteristics of a growing sea during hurricanes are significantly different from those observed in ordinary storms since the source of energy generating waves is moving and the rate of change of wind speed is very fast. This thesis presents the results of a study on the growth of sea severity during hurricanes with the aid of a wave spectral formulation representing the associated sea conditions. Through analysis of spectra obtained from wave data during the growing stage of five hurricanes, it is found that the Modified JONSWAP spectral formulation well represents field data over a wide range of frequencies. This enables us to evaluate the general trend of the growth of a hurricane generated sea by applying the Modified JONSWAP spectrum. The two parameters (significant wave height and modal frequency) involved in the Modified JONSWAP spectrum are presented as a function of wind speed which permits the presentation of the growth of the wave spectrum as a function of wind speed. It is found that, during the growing stage of a hurricane, the increase in wave energy in the neighborhood of the modal frequency is much greater than that at any other frequency of the spectrum.

Hurricanes are one of the most adverse aspects of the ocean environment, with the potential to cause a disastrous event for marine systems in the ocean. Hurricane Generated Seas is an invaluable reference for all involved in the field of naval, ocean and coastal engineering. The work clarifies hurricane generated sea conditions necessary for the design and operation of marine systems in a seaway, and provides information for the protection of near shore / onshore structures and the environment at the time of hurricane landing. Reveals Information vital for avoidance of disastrous events experienced by ships and offshore structures Includes detailed analysis of hurricane sea wave data obtained by buoys

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.

Waves critically affect man in coastal regions, including the open coasts and adjacent continental shelves. Preventing beach erosion, designing and building structures, designing and operating ships, providing marine forecasts, and coastal planning are but a few examples of projects for which extensive information about wave conditions is critical. Scientific studies, especially those in volving coastal processes and the development of better wave prediction models, also require wave condition information. How ever, wave conditions along and off the coasts of the United States have not been adequately determined. The main categories of available wave data are visual estimates of wave conditions made from ships at sea, scientific measurements of waves made for short time periods at specific locations, and a small number of long-term measurements made from piers or offshore platforms. With these considerations in mind, the National Ocean Survey of the National Oceanic and Atmospheric Administration sponsored the Ocean Wave Climate Symposium at Herndon, Virginia, July 12-14, 1977. This volume contains papers presented at this symposium. A goal of the symposium was to establish the foundations for a com prehensive and far-sighted wave measurement and analysis program to fully describe the coastal wave climate of the United States. Emphasis was placed on ocean engineering and scientific uses of wave data, existing wave monitoring programs, and modern measure ment techniques which may provide currently needed data.

Changes in sea surface roughness are usually associated with a change in the sea surface wind field. This interaction has been exploited to measure sea surface wind speed by scatterometry. A number of features on the sea surface associated with changes in roughness can be observed by synthetic aperture radar (SAR) because of the change in Bragg backscatter of the radar signal by damping of the resonant ocean capillary waves. With various radar frequencies, resolutions, and modes of polarization, sea surface features have been analyzed in numerous campaigns, bringing various datasets together, thus allowing for new insights into small-scale processes at a larger areal coverage. This Special Issue aims at investigating sea surface features detected by high spatial resolution radar systems, such as SAR.

This book addresses the issue of climate change risks and hazards holistically. Climate change adaptation aims at managing climate risks and hazards to an acceptable level, taking advantage of any positive opportunities that may arise. At the same time, developing suitable responses to hazards for communities and users of climate services is important in ensuring the success of adaptation measures. But despite this, knowledge about adaptation options, including possible actions that can be implemented to improve adaptation and reduce the impacts of climate change hazards, is still limited. Addressing this need, the book presents studies and research findings and offers a catalogue of potential adaptation options that can be explored. It also includes case studies providing illustrative and inspiring examples of how we can adapt to a changing climate.
