Many papers have been reported the arch-type separating shear layer and Karman vortices formed around a cubic building in a smooth flow. And so various vortices except aforesaid vortices, for example “trailing vortices”, has been formed when flow attacks at a front side of the building. In this report we studied the phenomenon of these vortices by flow visualization and tried to inspect the relation to the fluctuating pressures in a wind tunnel. As a result, the fluctuating pressures reflect the phenomenon of flow visualization. That is, the Karman vortices affect the windward flow and the switching of trailing vortices on the ridgeline between the roof and the side affect the leeward flow.
