Direct observations of airflow separation over ocean surface waves [PDF]

Nature Communications
A large portion of the kinetic energy found within the ocean originates from the growth of ocean surface waves under the action of wind. However our understanding of wind wave dynamical coupling mechanisms remains incomplete. Competing theories exist but

Differential impacts of wind and waves on albatross flight performance in two ocean basins [PDF]

Movement Ecology
Background Albatrosses can commute long distances to feed during the breeding season by avoiding energetically costly flapping flight. Energy from both wind and waves can be used to sustain soaring and reduce flapping flight, yet most studies of ...

Mountain waves can impact wind power generation [PDF]

Wind Energy Science, 2021
Mountains can modify the weather downstream of the terrain. In particular, when stably stratified air ascends a mountain barrier, buoyancy perturbations develop.

Phase Evolution of the Time- and Space-Like Peregrine Breather in a Laboratory

Fluids, 2021
Coherent wave groups are not only characterized by the intrinsic shape of the wave packet, but also by the underlying phase evolution during the propagation.

Effects of current on wind waves in strong winds [PDF]

Ocean Science, 2020
It is important to investigate the effects of current on wind waves, called the Doppler shift, at both normal and extremely high wind speeds. Three different types of wind-wave tanks along with a fan and pump are used to demonstrate wind waves and ...

The Capillary Waves’ Contribution to Wind-Wave Generation

Fluids, 2022
Published theories and observations have shown that dissipation of gravity waves implies frequency downshifting of wave energy. Hence, for wind-waves, the wind energy input to the highest frequencies is of special interest.

Nonlinear wave evolution with data-driven breaking

Nature Communications, 2022
Wave breaking mechanisms relevant for modelling of ocean-atmosphere interaction and rogue waves, remain computationally challenging. The authors propose a machine learning framework for prediction of breaking and its effects on wave evolution that can be

Water Exchange Due to Wind and Waves in a Monsoon Prevailing Tropical Atoll

Journal of Marine Science and Engineering, 2023
Physical forcings affect water exchange in coral reef atolls. Characteristics of the consequent water exchange depend on the atoll morphology and the local atmospheric and hydrographic conditions.

Research on the influential characteristics of asymmetric wind fields on typhoon waves

Frontiers in Marine Science, 2023
The East China Sea is an ocean region with frequent typhoons, typhoons are also the main reason for inducing typhoon waves. The complexity of typhoon waves is closely related to the complexity of typhoon wind field.

Experimental Research on the Dynamic Characteristics of Offshore Wind Turbine Model Under the Action of Highly Nonlinear Waves

南方能源建设, 2023
[Introduction] Monopile foundation is currently the most widely used support structure for offshore wind farms. For offshore wind farms in the medium water depth area such as Dafeng, Binhai and Sheyang in China, the design waves are very close to the ...
