dc.description.abstractThe spectral method of sea and swell wave forecasting yields more meaningful results than do other forecasting methods. To shorten the time required to make such a forecast the authors used high-speed computer methods and the Piers on-Neumann-James spectra to make spectral forecasts and display the results in graphic form for several synoptic weather models and a wide range of wind and fetch speeds. Forecasts were completed for a stationary fetch model, a fetch moving to leeward and a fetch moving to windward . Computations were made with the assumptions that a rectangular generating area could be delineated; that a spatially-uniform mean wind existed; that this wind did not increase or decrease until the time of forecast; and finally that if the fetch were moving, its movement was steady. The following parameter limits were established: a. wind speeds, 15 to 55 knots; b. speed of the generating area, 15 knots to and including the wind speed ; c. forecast times, 6 to 72 hours. Results of the forecasts are plotted on approximately 250 graphs which show the geographic distribution of spectral sea or swell components relative to the fetch at forecast times.en_US
