This study undertakes a spectral analysis of the wind load on a cubical body placed in a deep turbulent boundary layer. The experiment was made in an atmospheric boundary wind tunnel with a single cube, which has a number of pressure tappings on the salient points around the bodies. In order to understand the periodic and the correlation features, the spectral analysis has been made by using the typical Fourier transform and Cross correlation. In the result, the spectrums of surface pressure on the front, side and back face are substantially different each other. The spectrum of the front and back face are similar each other depending on the location and the spectrum peak on the side face gradually increases as it goes to the tailing edge. The correlation between the surface pressure and the wind load changes the characteristics of delay time depending on the location of separation and reattachment.
