This paper considers the dependence of pressure fields on surfaces of rectangular prisms obtained from wind tunnel experiments on boundary layer characteristics. Six different variants of boundary layer flows were simulated in the wind tunnel. The qualitative coefficients of correlation Rs between the wind pressure coefficient Cp or its standard deviation σp and parameters describing boundary layer flows (wind speed profile, turbulence intensity profile, power spectral density) were estimated in order to determine how wind parameters influence surface pressure. Five rectangular prisms were placed in the wind tunnel. The following ratios of prism dimensions were adopted: D/B/H = 1:2:20 (R5); 1:2:10 (R3); 1:2:5 (R1); 1:4:20 (R4); 1:4:10 (R2).
