ResumoThis paper presents comparisons of full-scale measurements of the mean wind speed and mean wind direction at several points in a plaza located in a built-up urban environment with similar measurements obtained in a scaled boundary layer wind tunnel model study. Full-scale measurements were carried out with a portable propeller vane anemometer positioned at a height of 9 ft. above local ground. Full-scale measurements were carried out over approximately a two-week period. Wind tunnel measurements of wind speed were carried out with special single-ended hot film anemometer probes. Measurements of wind direction in the wind tunnel were made with a flow indicator consisting of a light sphere mounted on a flexible support. Although the full-scale data base was not adequate to allow a comprehensive comparison, the agreement between the full-scale and model observations was encouranging, particularly in windy areas of the plaza. The agreement between wind tunnel and full-scale mean wind speeds was found to be within about 10% for relatively windy areas of the plaza.
