## Abstract Many recent measurements of vertical‐velocity spectra in the atmospheric boundary layer are combined in order to derive the dependence of the maximum of the logarithmic spectrum, normalized by surface stress, on stability. An empirical equation is suggested which fits the observations a

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.

An indirect method of estimating the surface heat flux from observations of vertical velocity variance at the lower mid-levels of the convective atmospheric boundary layer is described. Comparison of surface heat flux estimates with those from boundary-layer heating rates is good, and this method se

## Abstract Observations of a considerable number of vertical‐velocity spectra are combined to show that under near‐neutral and unstable conditions, the shape of the spectrum is essentially invariant up to heights of order 100 m, and the β€˜scale’ of turbulence is proportional to height within this r

## 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 c
