Based on the improved statistics model of breaking waves, we have calculated the following statistical quantities: S_t, breaking area ratio generated per unit time; V_t, the volume of water mass thrown out from the wave surface due to breaking on a unit area per unit time; (?)_t, the breaking energy loss rate on a unit area per unit time. Under the high sea state, the phase change governed by wave breaking is mechanistic. Based on the physical and dimensional consideration we have also derived the statistical quantities of upper ocean dynamics such as whitecap coverage, exchange fluxes in the high sea state and turbulence degree in the subsurface layer. The theoretical results are consistent with the existing experimental data.
