Predicting rogue waves in random oceanic sea states
Using the inverse spectral theory of the nonlinear Schrödinger (NLS) equation we correlate the development of rogue waves in oceanic sea states characterized by the JONSWAP spectrum with the proximity to homoclinic solutions of the NLS equation. We find in numerical simulations of the NLS equation that rogue waves develop for JONSWAP initial data that is “near” NLS homoclinic data, while rogue ...
متن کاملRogue waves
“It came from nowhere, snapping giant ships in two. No one believed the survivors ... until now” screamed the cover of New Scientist magazine on 30 June 2001, introducing an article entitled “Monsters of the Deep”. The power and danger suggested by the term “rogue” add to the public fascination with extreme ocean waves, but they also present important and challenging scientific problems and pro...
متن کاملOutcomes of the Special Issue on Extreme and Rogue Waves
The session on “Extreme and Rogue Waves” has been proposed and successfully run for ten years by the Natural Hazard Division of the European Geosciences Union, previously known as the European Geophysical Society. Proceedings of the session were published by Pelinovsky and Kharif (2006, 2008), Kharif et al. (2006) and Pelinovsky et al. (2009). Progresses in this field are further documented by ...
متن کاملExciting rogue waves
Rogue waves [1]—extreme ocean waves with heights up to thirty meters—have been common elements in stories from people working at sea, as well as in popular fiction. It is not hard to imagine why: being on a small boat in a stormy sea swell and suddenly encountering a wave maybe three times as high as the surrounding waves is a terrifying experience (Fig. 1). However, up to a few decades ago, oc...
متن کاملDeterministic optical rogue waves.
Experimental observations of rare giant pulses or rogue waves were done in the output intensity of an optically injected semiconductor laser. The long-tailed probability distribution function of the pulse amplitude displays clear non-Gaussian features that confirm the rogue wave character of the intensity pulsations. Simulations of a simple rate equation model show good qualitative agreement wi...
