Abstract

THIS STUDY EXAMINES THE SPECIFIC QUESTION OF WHETHER THERE ARE DIFFERENCES AMONG THESE MODELS SUCH THAT EVEN IF THE WIND FIELD WERE SPECIFIED PERFECTLY, THERE WOULD REMAIN SIGNIFICANT DEVIATIONS AMONG PREDICTED WAVES. FIRST, WAVE GENERATION UNDER UNIFORM WIND FIELDS IS COMPARED BY USE OF NONDIMENSIONAL PARAMETERS. THEN THE MODELS ARE COMPARED AGAIN UNDER CONDITIONS OF TIME-VARYING, SPACE-VARYING WIND FIELDS AND WITHIRREGULAR FETCH BOUNDARIES. IT IS CONCLUDED THAT, IN THE OPEN OCEAN WITH A LONG-DURATION, SLOWLY VARYING WEATHER SYSTEM, MOST MODELS PRODUCE SIMILAR RESULTS; HOWEVER, NEAR A COASTOR IN REGIONS WITH RAPIDLY VARYING WEATHER SYSTEMS, MARKED DIFFERENCES CAN BE EXPECTED FROM THE USE OF DIFFERENT MODELS.
