Abstract

Turbulence measurements were made in the first thirty meters of the atmosphere. Direct measurement of turbulent fluctuations enhances the presentation of data in the context of the Monin-Obukhov similarity theory. It also allowed a detailed study of the turbulent energy budget as well as turbulence statistics in the surface boundary layer. Turbulence statistics are analysed and interpreted in relation to parameters such as height, mean wind speed and stability conditions. Terms in the budget equation of turbulent energy were derived from turbulence statistics. The vertical structure and temporal change of turbulent energy budget are pointed out for unstable and stable conditions. Finally a model for turbulent energy, deduced from the results, is presented. A general specification of the turbulent energy budget including the case of stable conditions has been achieved.
