The CYCLE 2 version of the WAM (Wave Model) model is used to hinfcast global ocean wave spectra, using the NMC (National Meteorological Center) winds, for a period of about 60 days. The results of the WAM waves and the NMC winds are compared with the NDBC (National Data Buoy Center) buoy data and the results of other models. The comparison indicates that although the WAM model predicts low estimates of the significant wave height when compared with the buoy data, its accuracy is slightly more favorable than the other models. However, the CPU time from the WAM model is about ten times longer than the other models.
