A simple model of the scaling parameter (fc) as a function of z/L for a stable surface layer is developed. This model is used to derive empirical forms for curves presented by Kaimal et al. (1972). Also obtained is the peak of the frequency and the maximum value of the logarithmic spectra as a funct

Abstract
Results of our recent investigation of spectral measurements of wind velocity in the surface layer are analysed in light of the hypothesis proposed by Kaimal et al. (1972). It is confirmed that in the inertial subrange the spectra for all the three components and varying stability converge to a −2/3 line at the high frequency end. At the low frequency end the spectra cluster together in random fashion in a certain bandwidth and do not show any ordered arrangement with z/L.

Measurements of the velocity circulation in the atmospheric surface layer can be used to infer information on atmospheric vorticity, a quantity of fundamental importance. In this paper, circulation is measured with an acoustic sensor. The instrument is described, and some results are given.
It is shown that the ratio of standard deviation of lateral velocity to the friction velocity, o;/u,, and therefore wind direction fluctuations, are sensitive to mesoscale terrain properties. Under neutral conditions, a,/~, is almost 40% larger in rolling terrain than over a horizontal surface. In
