Wavelet study of approach-wind velocity and building pressure

Application of wavelet transform (WT) to study approach wind speed and building roof pressure is described in the paper. The WT is briefly introduced and employed in two illustrative examples, and in analysis of wind-tunnel data. The local wavelet spectra and other WT-based quantities are presented. Significant variation in the local energy, not accounted for in Fourier spectra analysis, is noted. Further study of these variations and their effects on wind-induced loading, as well as investigations of physical processes associated with patterns exhibited by the WT results, are desired.
