Results given from wind tunnel experiments on the flow and temperature fields around urban street canyons are presented. 3D Laser Doppler Velocimeter(LDV) and cold wire were used for measuring the instantaneous flow and temperature fields. Profiles of mean wind speed, mean temperature, variances and also momentum flux and heat flux were strongly dependent on stabiHty conditions. A steady cavity eddy was formed just before the front surface of building blocks in a model street canyon. The intensity of the cavity eddy was also affected by stability conditions strongly.
