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 …

On a unified breaking onset threshold for gravity waves in deep and intermediate depth water

X Barthelemy, ML Banner, WL Peirson… - Journal of Fluid …, 2018 - cambridge.org
We revisit the classical but as yet unresolved problem of predicting the breaking onset of 2D
and 3D irrotational gravity water waves. Based on a fully nonlinear 3D boundary element …

Large nearshore storm waves off the Irish coast

F Fedele, J Herterich, A Tayfun, F Dias - Scientific reports, 2019 - nature.com
We present a statistical analysis of nearshore waves observed during two major North–East
Atlantic storms in 2015 and 2017. Surface elevations were measured with a 5-beam …

[HTML][HTML] Lagrangian kinematic criterion for the breaking of shoaling waves

U Itay, D Liberzon - Journal of Physical Oceanography, 2017 - journals.ametsoc.org
An experimental study was conducted with the aim of validating the Lagrangian kinematic
criterion (LKC) for the case of breaking of shoaling waves. Monochromatic wave trains were …

Crest speeds of unsteady surface water waves

F Fedele, ML Banner, X Barthelemy - Journal of Fluid Mechanics, 2020 - cambridge.org
Intuitively, crest speeds of water waves are assumed to match their phase speeds. However,
this is generally not the case for natural waves within unsteady wave groups. This motivates …
