Abstract:

Scalar exchange between the atmosphere and ocean. This is particularly important at high winds since air-sea coupling controls tropical cyclone hurricane formation and intensity. There is large uncertainty in the bulk momentum and heat surface exchange coefficients Cd, Ck derived from field observations and laboratory experiments for varying wind speed, wave age, swell amplitude and direction, and in the presence of spray, with an even greater debate as to the underlying dynamical processes that couple the winds and waves. In this context, the overarching theme of this project is to identify the physical processes that couple winds in the marine atmospheric boundary layer and the underlying surface gravity wave field at high wind speeds.
