Bubbles Produced by Breaking Wind Waves

摘要: Many air-sea interaction processes, including gas transfer, involve bubbles produced by breaking waves. Laboratory measurements of were performed under various wind and wave conditions. The size spectra found to vary with depth, larger vanishing more rapidly downward. bubble population decays exponentially depth; the characteristic entrainment depth is about one height. at water surface was be proportional fifth power velocity moderate winds (wind-shear smaller than 80 cm/s). For high winds, shifted 2.5, indicating different processes in two wind-velocity ranges.
