Rogue waves and wave breaking – How are these phenomena related?
نویسنده
چکیده
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 waves seems to occur more frequently than rogue waves. This contribution seeks to highlight the role of the modulation process in these two “extreme” wave phenomena from observational and computational perspectives, with the aim of stimulating discussion on what differentiates the more commonly observed phenomenon of wave breaking from the more elusive rogue waves.

Steep. Short-Crested Waves and Related Phenomena
Steep, short-crested waves, as well as a large variety of three-dimensional propagating wave patterns have been created in laboratory, utilizing a plunging half-cone. Monochromatic waves, over a range of frequencies and amplitudes through breaking and including soliton wave groups near resonance, have been observed and studied in a small wave flume. This monochromatic wavemaker creates complex ...
متن کاملExtreme wave phenomena in down - stream running modulated waves
Modulational, Benjamin-Feir, instability is studied for the down-stream evolution of surface gravity waves. An explicit solution, the soliton on finite background, of the NLS equation in physical space is used to study various phenomena in detail. It is shown that for sufficiently long modulation lengths, at a unique position where the largest waves appear, phase singularities are present in th...
متن کاملStatistical Investigation of the Surface Profile of Rogue Waves in 2d Non-breaking Seas
Rogue waves or freak waves are very large amplitude waves compare to the ambient waves in a given sea state. There are very few recording of such waves and therefore, despite years of research, very little is known about their properties. Here we invoke a statistical approach to find out about the typical shape of these giant waves. We consider different sea states and unidirectional vs crossin...
متن کاملDynamics of Rogue Waves on a Multisoliton Background in a Vector Nonlinear Schrödinger Equation
General higher order rogue waves of a vector nonlinear Schrödinger equation (Manakov system) are derived using a Darboux-dressing transformation with an asymptotic expansion method. The Nth order semi-rational solutions containing 3N free parameters are expressed in separation of variables form. These solutions exhibit rogue waves on a multisoliton background. They demonstrate that the structur...
متن کاملObservation of a hierarchy of up to fifth-order rogue waves in a water tank.
We present experimental observations of the hierarchy of rational breather solutions of the nonlinear Schrödinger equation (NLS) generated in a water wave tank. First, five breathers of the infinite hierarchy have been successfully generated, thus confirming the theoretical predictions of their existence. Breathers of orders higher than five appeared to be unstable relative to the wave-breaking...
