Abstract : The model described here refines earlier FNWC singular models in four major areas: (a) Improved corrections to geostrophic input winds, (b) revised growth equation designed to handle the most common cases of growth versus duration, (c) empirical decay functions based upon recent studies of swell from distant storms and (d) built-in verification routines to facilitate tuning. This model is capable of producing operationally useful wind-wave analyses/forecasts commensurate with wind forecast accuracy. The swell portion of the model predicted damaging surf conditions from winter storms north of Hawaii which had not been correctly treated by earlier models.
