One of the difficulties in full scale measurements in urban area exists in the installation of an anemometer at an appropriate position without any influences of the obstacles. In order to determine the appropriate measuring position above the building and to provide a basic reference of influence correction, wind tunnel studies were carried out for several building models which are considered as typical building shapes in urban area. As a result, variations of the mean wind velocity profile and turbulence intensity profile, and of the spectral density distributions are presented and discussed comparing with those of the original flow free from the obstacles.
