ON THE COEFFICIENT OF TURBULENT EXCHANGE IN THE FRICTIONAL LAYER,

Abstract

The austausch coefficient in the frictional layer may be evaluated from a knowledge of the wind structure in this stratum. A general formula is obtained. It is shown that the Laikhtman formula is a particular case of this general formula for a stationary temperature-pressure field with uniform pressure gradient and constant temperature. Similarly, the Ekman formula is another particular case of the general formula for a stable pressure field when temperature remains constant with respect to time and space. Thus the general formula given is more accurate for the evaluation of the austausch coefficient and can cope with a wide range of applications. Finally, some computations from observational data are made and analyzed together with a discussion on the variation of the austausch coefficient in a natural environment. (Author)
