Real world ocean rogue waves explained without the modulational instability

F Fedele, J Brennan, S Ponce de León, J Dudley… - Scientific reports, 2016 - nature.com
Since the 1990s, the modulational instability has commonly been used to explain the
occurrence of rogue waves that appear from nowhere in the open ocean. However, the …

Distribution of sea-surface elevations in intermediate and shallow water depths

MA Tayfun, MA Alkhalidi - Coastal Engineering, 2020 - Elsevier
Waveforms described by the second-order Stokes-type approximations are prone to display
anomalous troughs with spurious negative crests. The systemic occurrence of such …

Machine-guided discovery of a real-world rogue wave model

D Häfner, J Gemmrich… - Proceedings of the …, 2023 - National Acad Sciences
Big data and large-scale machine learning have had a profound impact on science and
engineering, particularly in fields focused on forecasting and prediction. Yet, it is still not …

Offshore stereo measurements of gravity waves

A Benetazzo, F Fedele, G Gallego, PC Shih, A Yezzi - Coastal Engineering, 2012 - Elsevier
Stereo video techniques are effective for estimating the space-time wave dynamics over an
area of the ocean. Indeed, a stereo camera view allows retrieval of both spatial and temporal …

Observation of extreme sea waves in a space–time ensemble

A Benetazzo, F Barbariol… - Journal of Physical …, 2015 - journals.ametsoc.org
In this paper, an observational space–time ensemble of sea surface elevations is
investigated in search of the highest waves of the sea state. Wave data were gathered by …

[HTML][HTML] Wave modulation in a strong tidal current and its impact on extreme waves

T Halsne, A Benetazzo, F Barbariol… - Journal of Physical …, 2024 - journals.ametsoc.org
Accurate estimates of extreme waves are central for maritime activities, and stochastic wave

Reduced-order precursors of rare events in unidirectional nonlinear water waves

W Cousins, TP Sapsis - Journal of Fluid Mechanics, 2016 - cambridge.org
We consider the problem of short-term prediction of rare, extreme water waves in irregular
unidirectional fields, a critical topic for ocean structures and naval operations. One possible …

Space–time measurements of oceanic sea states

F Fedele, A Benetazzo, G Gallego, PC Shih, A Yezzi… - Ocean Modelling, 2013 - Elsevier
Stereo video techniques are effective for estimating the space–time wave dynamics over an
area of the ocean. Indeed, a stereo camera view allows retrieval of both spatial and temporal …

Can rogue waves be predicted using characteristic wave parameters?

AD Cattrell, M Srokosz, BI Moat… - Journal of Geophysical …, 2018 - Wiley Online Library
Rogue waves are ocean surface waves larger than the surrounding sea that can pose a
danger to ships and offshore structures. They are often deemed unpredictable without …
