Abstract: This paper describes the development and application of a graphical technique to the determination of maximum significant wave heights and periods attained by waves in moving wind systems. Existing deep water forecasting data, representing the work of Sverdrup and Munk (1941) and modifications since introduced by Arthur (1951), Bretschneider (1951, 1952), are assembled in a single chart over which a space-time wind-field representing any given moving wind system (in relation to a particular point on a coast) can be placed by superposition for the evaluation of the characteristics of the waves generated at any specific point in space and time within the wind field. The space-time tracks of the waves can then be followed in their advance to the coastal station and the time of arrival, heights and periods there determined to give in effect a synthetically constructed wave spectrum for forecasting or hindcasting purposes. The method is applicable to both approaching and receding storms and permits of decay aspects being taken into account in the usual way. An example is given of the application of the method to the forecasting of wave conditions in the path of a hurricane.
