摘要

In this paper a review is given on the evolutionary properties of mechanically generated extreme waves induced by nonlinear wave focusing. To be more close to the realistic sea states, not only unidirectional waves but also directional waves characterized by different directional spreading effects are considered herein. Particular attention is paid to the variation of characteristics of 2D extreme waves because their corresponding evolutionary tendency can be clearly divided into several critical stages and associated energy exchange in this process can be discussed from a statistical point of view. Moreover, four typical phase-resolving deterministic models that can account for the third-order nonlinear mechanism are briefly commented based on their features in stochastic analysis of extreme waves with Monte Carlo simulations.
