Coasts Waves And Weather

This guide for boaters in the Great Lakes region begins with basic information about the weather, the atmosphere, clouds, fog, regional and near-shore wind effects, and waves. It also reviews the hazards from thunderstorms, intense lows, and winter conditions, and what boaters can do to face them. It then outlines how to prepare for possible marine emergencies and the hazards associated with immersion in cold water. This is followed by a guide to local conditions on Lake Ontario, Lake Erie, Lake Huron and Georgian Bay, Lake Superior, and smaller lakes such as Simcoe and Nipigon. The final section describes marine weather services available in the Great Lakes region and how to access marine weather forecast information. Includes index.

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.

Observations of wave motion phenomena in nature are essential, but laboratory studies leading to the evaluation of existing theories may be invaluable as a guide to field observation programs and technique. The purpose of the study is to seek laboratory experimental confirmation of oscillatory wave characteristics.

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.
