本文报道了第一次实验室研究的结果，研究了短风浪的初始增长与风致漂移流的同步发展之间的关系。解释了第一道可见波纹“突然”出现在水面上并形成与风向一致的V形条纹的现象。我们发现，近地表水流的层流湍流过渡导致爆炸性增长的初始风产生的涟漪。生长的波纹变得可见，从而标记形成条纹的良好局部化的V形湍流区的表面。
In this paper we report the results of the first laboratory study on the relationship between the initial growth of the short wind waves and the simultaneous development of the wind-induced drift current. The phenomenon of the first visible ripples appearing “suddenly” on the water surface and forming V-shaped streaks aligned with the wind is explained. We show that the laminar–turbulent transition of the near surface water flow causes an explosive growth of the initial wind-generated ripples. The grown ripples become visible and thus mark the surface of the well-localized V-shaped turbulent zones forming the streaks.
