HEAT FLUX AND SURFACE STRESS ON AND NEAR AN ISLAND IN THE TRADE WIND REGION.
Abstract
The present state of work under the contract is reviewed. It is then shown that the drag coefficient over water is likely to be a function of fetch and wind duration. Observational data are analyzed to specify this relationship. The boundary layer over water is discussed. A double viscous sublayer characterizes the existing regime. Boundary layer separation appears to be a relatively rare event. The motion field has the character of a smooth flow over large parts of the sea surface. The investigation indicates that spray plays only a minor role in momentum transfer, at least at wind velocities below 10 meters per second. A theory has been established for the time-dependent depth and temperature of the midocean surface layer as a function of the interaction with the atmosphere. Large-scale circulation studies which include the effects of oceans on continent and the effects of seasons, were concluded. They will be resumed in a more sophisticated form at a later stage. Processing of Aruba data continues. (Author)
