On evolution of young wind waves in time and space

L Shemer - Atmosphere, 2019 - mdpi.com
The mechanisms governing the evolution of the wind-wave field in time and in space are not
yet fully understood. Various theoretical approaches have been offered to model wind-wave …

Wind generated rogue waves in an annular wave flume

A Toffoli, D Proment, H Salman, J Monbaliu, F Frascoli… - Physical review …, 2017 - APS
We investigate experimentally the statistical properties of a wind-generated wave field and
the spontaneous formation of rogue waves in an annular flume. Unlike many experiments on …

On the two-dimensional structure of short gravity waves in a wind wave tank

A Zavadsky, A Benetazzo, L Shemer - Physics of Fluids, 2017 - pubs.aip.org
Experiments on wind-waves in a laboratory tank are carried out for a variety of operational
conditions. In addition to using a conventional wave gauge to determine the temporal …

Evolution of waves in a horizontal pipe propagating on a surface of a liquid film sheared by gas

K Kumar, A Fershtman, D Barnea, L Shemer - Physics of Fluids, 2021 - pubs.aip.org
Different wavy regimes in stratified air–water pipe flow are determined for a wide range of
gas and liquid flow rates in a 10 m long horizontal pipe with a diameter of 24 mm. Three sub …

Statistical characterization of short wind waves from stereo images of the sea surface

AS Mironov, MV Yurovskaya, VA Dulov… - Journal of …, 2012 - Wiley Online Library
We propose a methodology to extract short‐scale statistical characteristics of the sea surface
topography by means of stereo image reconstruction. The possibilities and limitations of the …

The frequency selective effect of radar backscattering from multiscale sea surface

D Xie, KS Chen, J Zeng - Remote Sensing, 2019 - mdpi.com
The sea surface essentially contains multiscale roughness with capillary waves of many
sizes riding on large-scale waves that are also of many sizes. It is instructive to exploit the …

Interpreting sea surface slicks on the basis of the normalized radar cross‐section model using RADARSAT‐2 copolarization dual‐channel SAR images

DV Ivonin, S Skrunes, C Brekke… - Geophysical Research …, 2016 - Wiley Online Library
A simple automatic multipolarization technique for discrimination of main types of thin oil
films (of thickness less than the radio wave skin depth) from natural ones is proposed. It is …

Marine oil slicks quantification from L-band dual-polarization SAR imagery

O Boisot, S Angelliaume… - IEEE Transactions on …, 2018 - ieeexplore.ieee.org
We show, using simple physical models, that a quantitative estimation of the volume fraction
of marine oil slicks can be achieved from dual-polarization synthetic aperture radar (SAR) …

Evaluation of skewness and kurtosis of wind waves parameterized by JONSWAP spectra

SY Annenkov, VI Shrira - Journal of physical Oceanography, 2014 - journals.ametsoc.org
The authors consider the deviations of wave height statistics from Gaussianity, manifested in
higher statistical moments of random wind-wave fields, namely, in the nonzero values of the …

Spatial evolution of young wind waves: numerical modelling verified by experiments

L Shemer, SK Singh, A Chernyshova - Journal of Fluid Mechanics, 2020 - cambridge.org
A numerical model that allows one to study numerically the evolution of waves along the test
section of a wind-wave tank is offered. The simulations are directly related to wind-wave tank …
