| Abstract: | Whitecapping plays an important role in many air-sea exchange and upper ocean processes. Traditionally, whitecap coverage
is parameterized as a function of wind speed only. At present, the relative speed of ocean current to wind is considered to
be important in the air-sea exchange parameterization which is the function of wind speed only. In this paper, the effects
of ocean surface velocity (current velocity and wave induced velocity) and the wave parameters on whitecap coverage through
relative speeds are investigated, by applying a 2-parameter whitecap coverage model to the Atlantic Ocean. It is found that
the impacts of both current and wave on whitecap coverage are considerable in the most part of the Atlantic Ocean. It is interesting
that the effect of wave is more significant than that of current. |
