Abstract: In the first part of this paper the correlation function of measured wind spectra is compared with theoretical correlation models assuming a stationary wind process. This comparison indicates a good agreement between theory and experimental data. Furthermore the measured longitudinal wind - as well as lateral force spectra are fitted to respective models of spectral density functions. It is shown that theoretical models such as the modified Kaimal spectrum for the longitudinal turbulence and a hybrid force spectrum for the lateral excitation, respectively proves to be a good approximation for the measured power spectra.
