WebThe Miles-Phillips mechanism is a physical interpretation of these wind-generated surface waves. Both mechanisms are applied to gravity-capillary waves and have in common that waves are generated by a resonance phenomenon. The Miles mechanism is based on the hypothesis that waves arise as an instability of the sea-atmosphere system. [1] WebWhen the wind blows over the sea, it creates waves. The size and energy of the wave depends on certain factors: the fetch - how far the wave has travelled the strength of the …
