Rogue Wave Morphology in Broadband Nonbreaking Seas

  journal={arXiv: Fluid Dynamics},
Here, we show through a statistical analysis that rogue waves in broadband non-breaking seas are spatially asymmetric. In addition to the top-down asymmetry due to nonlinear effects, we show that the two troughs adjacent to the rogue wave crest are generally of different depths, which is unlike the conventional picture of rogue waves with symmetric fore and aft troughs often obtained from model equations. The rogue-wave trough asymmetry is demonstrated for sea states 4 to 6 on Douglas Sea Scale… Expand

N-fold Darboux transformation of the two-component Kundu–Eckhaus equations and non-symmetric doubly localized rogue waves
The two-component Kundu–Eckhaus (KE) equations were introduced for the first time in 1999. Very recently, the two-component KE equations considered as a model of describing the effect of quinticExpand


Oceanic Rogue Waves
Oceanic rogue waves are surface gravity waves whose wave heights are much larger than expected for the sea state. The common operational definition requires them to be at least twice as large as theExpand
Observations of the shape and group dynamics of rogue waves
Surface elevation records from two locations in the northeast Pacific are used to examine rogue waves and the relationship to wave groups. Three hundred individual rogue waves with heights greaterExpand
Rogue wave occurrence and dynamics by direct simulations of nonlinear wave-field evolution
Abstract We study the occurrence and dynamics of rogue waves in three-dimensional deep water using phase-resolved numerical simulations based on a high-order spectral (HOS) method. We obtain a largeExpand
Nonlinear Four-Wave Interactions and Freak Waves
Four-wave interactions are shown to play an important role in the evolution of the spectrum of surface gravity waves. This fact follows from direct simulations of an ensemble of ocean waves using theExpand
Predictability 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 extensiveExpand
Analysis of freak wave measurements in the Sea of Japan
Abstract This paper presents an analysis of a set of available freak wave measurements gathered from several periods of continuous wave recordings made in the Sea of Japan during 1986–1990 by theExpand
Distribution of crest heights in sea states with abnormal waves
Abstract The short-term statistical representation of wave crests in sea states with abnormal waves is discussed on the basis of comparison with the crest statistics in lower sea states. The analyzedExpand
Characteristics of abnormal waves in North Sea storm sea states
A data set of storm wave records from the North Sea is analysed. Using current definitions of abnormal waves, eight of the largest wind waves are defined as abnormal waves. Twenty-four of the largestExpand
Observation of rogue wave triplets in water waves
Abstract Doubly-localised breather solutions of the nonlinear Schrodinger equation (NLS) are considered to be appropriate models to describe rogue waves in water waves as well as in other nonlinearExpand
Circular rogue wave clusters.
This analysis reveals the existence of rogue wave clusters with a high level of symmetry in the (x,t) plane that arise naturally when the shifts in the Darboux scheme are taken to be eigenvalue dependent. Expand
