- Observation-based dissipation and input terms for WAVEWATCH III TM: implementation and simple simulations
- Zieger, Stefan; Babanin, Alexander V.; Rogersy, W. Erick; Young, Ian R.
- Observational data collected at Lake George, Australia resulted in new insights on the processes of wind wave interaction and white-capping dissipation and consequently new parameterisations of these source terms. The new wind input source term (Donelan et al., 2006; Babanin et al., 2007a) accounts for the dependence of growth increment on wave steepness, and on airflow separation with relative reduction of the growth under extreme wind conditions. The new white-capping dissipation source term (Babanin and Young, 2005; Young and Babanin, 2006) consists of two terms, the inherent breaking term and dissipation induced by longer waves. The present implementation follows Rogers et al. (submitted). Two novel parameterisations are validated against existing source terms and buoy measurements for windsea-dominated conditions in duration-limited simulations and hindcast.
