Nonlinear wave-wave interactions play a critical role in the evolution of wave spectra in tropical cyclones, transferring energy from wind-sea to remotely generated waves. The peak waves act in a parasitic manner, taking energy from wind-sea to sustain their growth. This study provides strong validation of the importance of nonlinear processes in wind-wave evolution.
A series of numerical experiments with the WAVEWATCH III spectral wave model are used to investigate the physics of wave evolution in tropical cyclones. Buoy observations show that tropical cyclone wave spectra are directionally skewed with a continuum of energy between locally generated wind-sea and remotely generated waves. These systems are often separated by more than 90 degrees. The model spectra are consistent with the observed buoy data and are shown to be governed by nonlinear wave-wave interactions that result in a cascade of energy from the wind-sea to the remotely generated spectral peak. The peak waves act in a parasitic'' manner taking energy from the wind-sea to maintain their growth. The critical role of nonlinear processes explains why one-dimensional tropical cyclone spectra have characteristics very similar to fetch-limited waves, even though the generation system is far more complex. The results also provide strong validation of the critical role nonlinear interactions play in wind-wave evolution.
