Experimental Study of Momentum Transfer, Heat and Water Vapor Fluxes Under Different Stability Conditions

Abstract

It is well knowft that the presence of a significant buoyancy flux associated with sensible and latent heat fluxes affects the tur burlent structure of the surface layer of the marine atmosphere, as is the case when air and water temperatures get different values: under such conditions the classical “neutral” description cannot be taken into account any more. Stability parameters have then to be introduced in the formulation of the various fluxes. This has already been studied by many authors and among them Monin and Obukov (1954), Businger (1973) and Kondo (1975) can be cited. The I.M.S.T. air-sea interaction facility has been specially designed to simulate -at least partially- the atmospheric stability effects. After preliminary studies on a one fifth scale model by Marmottant (1974) as well as on the large facility by Peri (1975) the authors have undertaken in 1975 a rather extensive laboratory study of the influence of stratification upon the momentum, heat and water vapor fluxes. Although the full program is not yet completed, the first experimental results are to be presented here.
