TL;DR: The influence of wind on extreme wave events in deep water is investigated experimentally and numerically as discussed by the authors, and it is found that wind blowing over a short wave group due to the dispersive focusing of a longer frequency-modulated wavetrain (chirped wave packet) may increase the time duration of the extreme wave event by delaying the defocusing stage.

TL;DR: In this paper, velocity and vorticity distributions over short-gravity breaking waves have been measured in a wind-wave tank, and the instantaneous flow topology displays specific features of three-dimensional separation patterns.

TL;DR: In this paper, the evolution of the airflow instantaneous structure over an unsteady breaking wave propagating in a group is measured in detail using the digital particle image velocimetry technique.

TL;DR: In this article, the authors compared first-order turbulence closure schemes based on the eddy viscosity concept and a second-order Reynolds stress model, and found that the overestimated modulation of the Reynolds stress gives a significant contribution to the wave growth rate.

TL;DR: In this paper, the authors compared the input of energy by wind to water waves with the observed growth of the waves using a suite of microphysical measurement techniques in the laboratory, including measured tangential stresses in the water and air immediately adjacent to the interface with corresponding form drag measurements above wind-forced freely propagating waves.
