## Abstract Methods of calculating the eddy diffusivity ΞΊ are discussed. It is shown that methods which assume that ΞΊ can be regarded as independent of the height, even through a shallow layer, lead to erroneous results: in consequence the frequent use in the literature of the approximate equation

## Abstract A semiβempirical treatment of the vertical diffusion of matter in the lowest layers of the atmosphere is given in the following and shown to be in good agreement with the results of carefully conducted field experiments made over two different types of natural land surface. The present
A scheme for the representation of the vertical eddy fluxes of heat, momentum and water vapour in a forecast model is presented. An important feature of the scheme is the dependence of the diffusion coefficients on the static stability of the atmosphere. Two tests are presented, using the scheme in
Diurnal variations of the vertical profiles of wind and temperature have been surveyed, and the diffusivity and the dimensionless gradient function in the atmospheric boundary layer have been estimated. Even in the middle of the atmospheric boundary layer (e.g., below a height of 442 m), the vertica
