Abstract : A single-layer theory is presented for the wind distribution in baroclinic neutral and unstable boundary layers. The theory predicts the stress of the wind on the ground from large scale geophysical parameters. A re-analysis of observations made by Swinbank confirms the validity of the Keyps wind profile theory. The effects of a change of roughness on the wind profile have been extended to diabatic surface layers. Also a study of the turbulent energy budget showed significant differences between the rate of production and rate of dissipation in the vicinity of a large change of terrain roughness. A graphical procedure for estimating the spectrum of the longitudinal wind component from the height, mean wind speed, surface roughness, and stability has been developed from observed spectra at many locations.
