EVALUATION OF SPECTRAL WAVE HINDCASTS USING THE AUTOMATED WAVE PREDICTION PROGRAM OF THE NAVAL OCEANOGRAPHIC OFFICE.
Abstract
For the past few years a spectral wave forecasting program has been under development at the Naval Oceanographic Office. Primarily designed as a first step for an automated aircraft carrier landing system this model, at present, represents the state of the art in ocean wave forecasting. The first section of this paper presents a brief historical summary and description of the wave forecasting model. In conjunction with New York University a forecast/hindcast evaluation program has been undertaken. The second section of this paper attempts to evaluate spectral hindcasts made in the vicinity of Bermuda, B.W.I. during the latter part of November 1961. Wave data recorded at ARGUS ISLAND, situated 25 miles SW of Bermuda, are the sole means of evaluation for the hindcasts. Comparisons of hindcasted to observed spectra are quite favorable. Rapidly changing synoptic conditions appear to be the major cause for discrepancies in the spectral comparisons. Modifications to the model for improved spectral forecasts are also discussed.
