Abstract: A new idea to incorporate the wave breaking phenomena in deep and shallow water in wind wavecurrent interaction process explicitly in atmosphere-wind wave-ocean coupled model has been proposed in this study. The whitecapping in deep water and the depth-induced wave breaking in shallow water are particularly considered in momentum transfer processes explicitly using common exchanging variables between wind wave and current models, while the turbulence production and other phenomena under wave breaking is considered implicitly using wave energy dissipation coefficients due to whitecapping and depth-induced wave breaking. From the preliminary results of three tropical storm events, distinctive features of spatial distribution of momentum flux due to wave breaking were found over the developed shelf areas, which should not be overlooked in shallow water dynamics.
