On Formation of the Rogue Waves and Holes in Ocean
نویسنده
چکیده
Two-dimensional nonlinear models are developed to account for abnormal surface ocean waves generation and propagation. These models are based on the KadomtsevPetviashvili equation, the 2D Benjamin-Ono equation and the 2D Gardner equation. Possible mechanisms of the waves formation suggested are the resonant interaction between semi-plane waves or waves with curved fronts or the transverse instability of a plane surface wave.

Controlling the Occurrence of Rogue Waves in an Optically Injected Semiconductor Laser via Changing The Injection Strength
The rouge waves in an optically injected semiconductor lasers are receiving a lot of interest. In this work, the generating and controlling of the rogue waves in semiconductor lasers have been investigated. For this purpose, the laser’s rate equations are solved numerically in a specified time interval, then the field amplitude and the intensity versus time are calculated and analyzed. To solve...
متن کاملPredictability horizon of oceanic rogue waves
Prediction is a central goal and a yet-unresolved challenge in the investigation of oceanic rogue waves. Here we define a horizon of predictability for oceanic rogue waves and derive, via extensive computational experiments, a statistically converged predictability time scale for these structures. We show that this time scale is a function of the sea state (i.e., severity of the ambient ocean w...
متن کاملOcean rogue waves and their phase space dynamics in the limit of a linear interference model
We reanalyse the probability for formation of extreme waves using the simple model of linear interference of a finite number of elementary waves with fixed amplitude and random phase fluctuations. Under these model assumptions no rogue waves appear when less than 10 elementary waves interfere with each other. Above this threshold rogue wave formation becomes increasingly likely, with appearance...
متن کاملRogue waves and wave breaking – How are these phenomena related?
According to prevailing ideas, the formation of rogue waves and the onset of wave breaking share a common physical framework: energy focusing within nonlinear wave groups. For 2D (one horizontal spatial direction) wave packet evolution, this correspondence appears to be very close. However, the situation is less clear for 3D propagation, and in the open ocean, observed breaking of dominant wind...
متن کاملHow to excite a rogue wave
Rogue waves are one of those fascinating destructive phenomena in nature that have not been fully explained so far 1–3 . There is a variety of approaches to deal with rogue waves 4,5 . Oceanographers commonly agree that linear theories cannot provide explanations for their existence 6,7 . Only nonlinear theories can explain the dramatic concentration of energy into a single “wall of water” well...
