In order to clarify characteristics of separated shear layers above a roof of a cubic model and wind pressures on the roof, a wind tunnel experiment was carried out. The flow was measured by Particle Image Velocimetry (PIV) system and simultaneous multi-pressure measurements on the roof surface were also performed. In this paper, relations between instantaneous separated shear layers above the roof and instantaneous wind pressure distributions were presented. Characteristics of instantaneous wind pressure distributions at the instantaneous reattachment were also discussed.
