TESTS ON SOME PROGRAMMED NUMERICAL FORCAST MODELS.

Abstract

NUMERICAL FORECASTING OF WIND-GENERATED OCEAN WAVES BY DIGITAL COMPUTER MAY BE ATTEMPTED USING ANY OF THREE FUNDAMENTALLY DIFFERENT WAYS OF DESCRIBING WAVE GENERATION AND DECAY: EMPIRICAL SIGNIFICANT WAVE, EMPIRICAL SPECTRAL, AND THEORETICAL SPECTRAL.THIS PAPER DESCRIBES FOUR MODELS, COVERING THE THREE TYPES, WHICH HAVE BEEN PROGRAMMED WITH A VIEW TO THE ADAPTATION OF ONE OR MORE INTO A NUMERICAL WAVE FORECAST SYSTEM FOR THE AUSTRALIAN REGION.RESULTS FROM A SIMPLE TEST SITUATION ARE PRESENTED, BOTH FOR COMPARISON PURPOSES AND AS A CHECK ON THE INTERNAL CONSISTENCY OF THE MODEL'S GENERATION AND DECAY FUNCTIONS.(A)
