| Zusammenfassung |
| The purpose of this study was to enhance the accuracy of numerical wave
forecasts through data assimilation during typhoon periods. A sequential data
assimilation scheme was modified to enable its use with partitions of
directional wave spectra. The performance of the system was investigated with
respect to operational applications, specifically for typhoon waves. Two
typhoons that occurred in 2006 around Taiwan (Kaemi and Shanshan) were used
for this case study. The proposed data assimilation method increased the
forecast accuracy in terms of wave parameters, such as wave height and
period. After assimilation, the shapes of directional spectra were much
closer to those reported from independent observations. |
