Gas exchange through air-sea interface is directly related to the
turbulence and molecular transport near the surface of the
ocean. This turbulence is mainly driven by wind, wind waves and their
breaking. A relationship between gas transfer velocity and a
parameter representing wave state and wave breaking dissipation is
proposed, and it is also simplified as a function of wind speed and
significant wave height. When the significant wave height is replaced
by wind speed further, this relationship is roughly consistent with
that of the current widely used proposed by Wanninkhof (1992). The
latter can be regarded as a special case of the former. It is shown
that the gas transfer velocity is strongly influenced by the state of
wind waves, with more developed waves corresponding to more efficient
gas exchange. It is indicated that the gas exchange through air-sea
interface is significantly enhanced by the turbulence induced by wave
breaking.
