Numerical Investigation of Spectral Evolution of Wind Waves. Part I: Wind-Input Source Function

摘要: Abstract This paper is dedicated to the investigation and calibration of parameterized form for wind-input source term Sin proposed earlier on basis field observations at Lake George, Australia. The main objective this study was obtain spectral forms function Sin, which incorporates novel observation-based features same time satisfies important physical constraint that total integrated wind input must agree with independently observed magnitudes stress. Within approach, a new methodology, dynamic self-adjusting routine, developed correction Sin. involves frequency-dependent adjustment growth rate γ( f ), based extrapolations from data. model results also show light winds require higher-rate adjustments than strong winds.
