ABSTRACT

Even if extreme events like rogue waves were shown to be highly nonlinear and asymmetric, the average profiles of real large waves were found to be close to symmetric around the instant when the maximum (or minimum) occurs (Santo et al., 2013). The determinism which arises from real waves was also proven recently by Boccotti (2011) comparing sequences of waves belonging to sea states with almost equal characteristics containing essentially the same extreme event.
