Abstract:

Four different numerical wave prediction models are used to hindcast wave conditions in Lake Michigan for a 10 day case in October, 1988. Results are compared to observed wave height and period measurements from two deep water NOAA weather buoys and from a nearshore Waverider buoy. The results of the comparison show that the accuracy of the interpolated wind fields is probably at least as important as differences in the wave prediction models in explaining the differences between observed and computed waves.
