The power spectral density G(f) = s squared f exp -1 for frequencies less than 10 Hz is shown to represent the observational characteristics of star image motion more correctly than the theoretical spectrum for the Kolmogorov atmospheric turbulence and the spectral model of Hog. A spectral density maximum in the frequency interval 0.0065-0.015 Hz is shown to exist. The present model agrees in general with knowledge on the turbulence spectrum and with experimental data on wind velocity and temperature fluctuations.
