High-Precision Simulation Study of Hurricane Juan-Generated Waves in Coastal Shallow Water

摘要

Hurricane Juan generated huge, complex waves in the Northwest Atlantic and in coastal waters off Nova Scotia in late September 2003. This study focuses on the accurate, high-precision simulation of waves generated by Hurricane Juan in coastal waters through the application of the WAVEWATCH III (WW3) and SWAN wave models. Cyclone-generated waves in coastal waters are very complex compared with those in offshore and ocean regions. Two issues are addressed that influence the accurate, high-precision simulation of cyclone-generated waves in coastal waters: (1) the SWAN model's numerical sensitivity during nonstationary simulations in coastal waters; and (2) the incoming two-dimensional wave spectral pattern at the model boundaries.
