How 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...
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 کاملTriangular rogue wave cascades.
By numerically applying the recursive Darboux transformation technique, we study high-order rational solutions of the nonlinear Schrödinger equation that appear spatiotemporally as triangular arrays of Peregrine solitons. These can be considered as rogue wave cascades and complement previously discovered circular cluster forms. In this analysis, we reveal a general parametric restriction for th...
متن کاملOptical Dark Rogue Wave.
Photonics enables to develop simple lab experiments that mimic water rogue wave generation phenomena, as well as relativistic gravitational effects such as event horizons, gravitational lensing and Hawking radiation. The basis for analog gravity experiments is light propagation through an effective moving medium obtained via the nonlinear response of the material. So far, analogue gravity kinem...
متن کاملRogue wave observation in a water wave tank.
The conventional definition of rogue waves in the ocean is that their heights, from crest to trough, are more than about twice the significant wave height, which is the average wave height of the largest one-third of nearby waves. When modeling deep water waves using the nonlinear Schrödinger equation, the most likely candidate satisfying this criterion is the so-called Peregrine solution. It i...
