The paper deals with results of measurements which have been carried out in the wind tunnel. Vertical, fixed prism of the cross-section dimensions 10 cm x 20 cm was the object of the experiment. Distributions of mean wind pressure coefficient on the surface of the prism were accepted as results presentation. The following parameters of the wind structure were analysed: vertical mean wind speed profile, turbulence intensity profile, power spectral density functions with respect to their influence on pressure coefficient values. Changes of the angle of wind attack were taken into consideration.
