Some experimental spectra of the v', w', and t' fluctuations in a stably stratified boundary layer are discussed that were obtained in the constant stress region of a laboratory boundary layer. It is shown that no buoyant subranges exist and that temperature-fluctuation and velocity-fluctuation spectra are roughly described at high frequencies by the universal laws of Kolmogoroff and Corrsin for the viscous subrange. Better agreement for the velocity spectra is found, however, by extending formally the k−1 law of Tschen and Gisina to higher wave numbers.
