Rogue waves in the sea: observations, physics, and mathematics

AV Slunyaev, DE Pelinovsky, EN Pelinovsky - Phys. Usp, 2023 - ufn.ru
Rogue waves are anomalously high waves that may suddenly form on the sea surface. At
the dawn of the 21st century, they attracted the interest of researchers, from oceanographers …

Why rogue waves occur atop abrupt depth transitions

Y Li, S Draycott, Y Zheng, Z Lin, TAA Adcock… - Journal of Fluid …, 2021 - cambridge.org
Abrupt depth transitions (ADTs) have recently been identified as potential causes of

Statistical distributions of free surface elevation and wave height for out-of-equilibrium sea-states provoked by strong depth variations

J Zhang, Y Ma, M Benoit - Ocean Engineering, 2024 - Elsevier
As unidirectional irregular wave trains propagate over a steep shoal, the sea-state becomes
out-of-equilibrium and is continuously affected by the non-equilibrium dynamics (NED) over …

Extreme wave statistics of surface elevation and velocity field of gravity waves over a two-dimensional bathymetry
