Directional spectrum of wind waves: Part II—comparison and confirmation

摘要: A model on the directional frequency spectrum of wind waves for deep water is introduced. The comparisons proposed with other existing models show that very close to JONSWAP and DHH describing developing under normal spectral bandwidth, has a better description transition unidirectional from ω−4 ω−5 at position around ωp, i. e., three time peak frequency. Comparisons also describes closely both field data measured by four-frequency radar laser-optical sensor, laboratory laser slope gauge an imaging optical method. further demonstrate inverse bandwidth as new wave parameter robust spectral, steepness. Finally, formula local spectral-peak angular confirmed using observed two-dimensional spectra.
