Doris: (top) crest heights h/hR and (bottom) crest-to-trough wave heights H/HR versus number of waves Nh(ξ). Empirical distributions (□) of total population of waves observed in comparison with non-stationary models (T = Tayfun, TF = Tayfun-Fedele, F = Forristall, B = generalized Boccotti and R = Rayleigh distributions). (Light gray lines) approximate confidence bands on observational estimates. Amplitude hR (HR) refers to Rayleigh-distributed crest (crest-to-trough) heights exceeded with probability P(ξ) in Gaussian seas.
