Functional differential equations and freak waves

From the summary: "In this paper we consider a very interesting oceanic phenomenon called `freak waves'. To model freak waves numerically and conduct important computational experiments, we use functional differential equations. par "Freak waves are unexpected waves with a huge amplitude (up to 30 meters). This event is momentary and, therefore, it is difficult to locate and predict. par "Our methods of simulation of ocean waves allow us to make direct simulations of freak waves."
