Abstract

Spectra of the time series of wind speeds and temperatures measured in the outflow area of a large drainage region are presented. Peaks are found in these spectra at frequencies corresponding to periods of oscillation of ∼1.5 h. A simple model is given, which accounts qualitatively for some of the observed features.
