Experimental Evidence of the Effect of Surface Waves on the Airflow
Publisher: American Meteorological Society
Abstract: Experimental evidence of the effect of surface waves on the airflow is presented. According to the quasi-linear theory of wind-wave generation, the stress of airflow over surface gravity waves depends on both wind speed ...
Quasi-linear Theory of Wind-Wave Generation Applied to Wave Forecasting
Publisher: American Meteorological Society
Abstract: The effect of wind-generated gravity waves on the airflow is discussed using quasi-linear theory of wind-wave generation. In this theory, both the effects of the waves and the effect of air turbulence on the mean wave ...

Nonlinear Four-Wave Interactions and Freak Waves
Publisher: American Meteorological Society
Abstract: Four-wave interactions are shown to play an important role in the evolution of the spectrum of surface gravity waves. This fact follows from direct simulations of an ensemble of ocean waves using the Zakharov equation. The ...
Wave-Induced Stress and the Drag of Air Flow over Sea Waves
Publisher: American Meteorological Society
Abstract: In this paper we are concerned with the effect of wind-generated, long gravity waves on the air flow. We study this example of resonant wave-mean flow interaction using the quasilinear theory of wind-wave generation. This ...
On the Effect of Ocean Waves on the Kinetic Energy Balance and Consequences for the Inertial Dissipation Technique
Publisher: American Meteorological Society
Abstract: For large wind speed (in practice >15 m s?1) observations of the surface stress by means of the inertial dissipation technique are so close to the surface that effects of growing ocean waves on the turbulent kinetic energy ...
The Intermediate Water Depth Limit of the Zakharov Equation and Consequences for Wave Prediction
Publisher: American Meteorological Society
Abstract: Finite-amplitude deep-water waves are subject to modulational instability, which eventually can lead to the formation of extreme waves. In shallow water, finite-amplitude surface gravity waves generate a current and ...
Ocean Waves and the Atmospheric Climate
Publisher: American Meteorological Society
Abstract: Ocean waves are generated by wind and, as a consequence, there is a considerable transfer of momentum from atmosphere to ocean. This momentum transfer depends, however, on the stage of development of the ocean waves. Ocean ...
