This book addresses the fascinating phenomena associated with
nonlinear waves and spatio-temporal patterns. These appear almost
everywhere in nature from sand bed forms to brain patterns, and yet
their understanding still presents fundamental scientific
challenges. The reader will learn here, in particular, about the
current state-of-the art and new results in: Nonlinear water waves:
resonance, solitons, focusing, Bose-Einstein condensation, as well
as and their relevance for the sea environment (sea-wind
interaction, sand bed forms, fiber clustering) Pattern formation in
non-equilibrium media: soap films, chimera patterns in oscillating
media, viscoelastic Couette-Taylor flow, flow in the wake behind a
heated cylinder, other pattern formation. The editors and authors
dedicate this book to the memory of Alexander Ezersky, Professor of
Fluid Mechanics at the University of Caen Normandie (France) from
September 2007 to July 2016. Before 2007, he had served as a Senior
Scientist at the Institute of Applied Physics of the Russian
Academy of Sciences in Nizhny Novgorod (Russia). The chapters have
been written by leading scientists in Nonlinear Physics, and the
topics chosen so as to cover all the fields to which Prof. Ezersky
himself contributed, by means of experimental, theoretical and
numerical approaches. The volume will appeal to advanced students
and researchers studying nonlinear waves and pattern dynamics, as
well as other scientists interested in their applications in
various natural media.
This revised and updated second edition details the vast progress
that has been achieved in the understanding of the physical
mechanisms of rogue wave phenomenon in recent years. The selected
articles address such issues as the formation of rogue waves due to
modulational instability of nonlinear wave field, physical and
statistical properties of extreme ocean wave generation in deep
water as well as in shallow water, various models of nonlinear
water waves, special analysis of nonlinear resonances between water
waves and the relation between in situ observations, experimental
data and rogue wave theories. In addition, recent results on
tsunami waves due to subaerial landslides are presented. This book
is written for specialists in the fields of fluid mechanics,
applied mathematics, nonlinear physics, physical oceanography and
geophysics, and for students learning these subjects.
"It came from nowhere, snapping giant ships in two. No one believed
the survivors . . . until now" -New Scientist magazine cover, June
30, 2001 Rogue waves are the focus of this book. They are among the
waves naturally - served by people on the sea surface that
represent an inseparable feature of the Ocean. Rogue waves appear
from nowhere, cause danger, and disappear at once. They may occur
on the surface of a relatively calm sea and not reach very high
amplitudes, but still be fatal for ships and crew due to their
unexpectedness and abnormal features. Seamen are known to be
unsurpassed authors of exciting and horrifying stories about the
sea and sea waves. This could explain why, despite the increasing
number of documented cases, that sailors' observations of "walls of
- ter" have been considered ctitious for a while. These stories are
now addressed again due to the amount of doubtless evidence of the
existence of the phenomenon, but still without suf cient
information to - able interested researchers and engineers to
completely understand it. The billows appear suddenly, exceeding
the surrounding waves by two times their size and more, and
obtaining many names: abnormal, exceptional, extreme, giant, huge,
s- den, episodic, freak, monster, rogue, vicious, killer, mad- or
rabid-dog waves, cape rollers, holes in the sea, walls of water,
three sisters, etc.
Extreme, freak or rogue waves are produced by a number of physical
mechanisms that focus the water-wave energy into a small area, due
to wave instability, chaotic behaviour, dispersion (frequency
modulation), refraction (presence of variable currents or bottom
topography), soliton interactions, etc. During the past thirty
years a number of physical models of the rogue wave phenomenon have
been intensively developed. Numerous experimental, statistical and
theoretical investigations are intended to understand the physics
of the huge wave formation, its relation to the environmental
conditions and to provide a freak wave design for engineering
purposes. The book details the vast progress that has been achieved
in the understanding of the physical mechanisms of rogue wave
phenomenon in recent years. The selected articles address such
issues as the formation of freak waves due to modulation
instability of nonlinear wave field, physical and statistical
properties of rogue wave generation in deep water and in shallow
water, various models of nonlinear water waves, special analysis of
nonlinear resonances between water waves and the relation between
observations and freak wave theories. The book is written for
specialists in the fields of fluid mechanics, applied mathematics,
nonlinear physics, physical oceanography and geophysics, and for
students learning these subjects.
