Fig. 5: Wave growth rate through the sheltering mechanism.
From: Direct observations of airflow separation over ocean surface waves
Dimensionless wave growth rate β, as a function of inverse wave age u*/c. Gray squares represent wave growth estimates from recent laboratory measurements9. Gray circles show past laboratory48 and field49 observations compiled by Plant50, while the dashed gray line represents the growth rate given by Miles' linear theory7 (see Komen et al.37, Janssen51). The black line is the slow wave ''nonseparated sheltering” growth rate13 from the current study (Eq. (2)), for wavelengths between 0.35 and 1 m.
