3. ABSTRACT 



Procedures used to evaluate a computerized numerical wave prediction 

 program are described. Statistical analyses were made using records from shipborne 

 wave meters or a wave staff at five different locations in the North Atlantic and 

 machine-made predictions of wave spectra for forecast intervals up to 36 hours. 

 Comparisons are shown between two different sets of input data. The results of 

 the evaluation indicate that automated numerical wave spectral predictions are 

 feasible and that the forecasts are within a reasonable degree of accuracy for 

 forecast intervals up to 36 hours.
