dc.description.abstractMean wind velocity and temperature profiles were measured in a wind-tunnel boundary layer made thermally stable or unstable (corresponding to inversion and lapse conditions) by flow over a horizontal flat plate (29 m long and 2 m wide) which was either cooled or heated along the downstream 13 m. These profiles for heights from just above the viscous region up to half the boundary-layer thickness (about 55 cm) were fitted to the log-plus-linear and log-plus-linear plus-square relationships. Field data consisting of mean temperature and wind speeds taken at heights from 0. 25 m up to 16m were also plotted. Similarity between the mean wind velocity and the mean temperature profiles for both laboratory and field data was found to exist. Retainment of the square term in the series approximation of the dimensionless wind shear for the case of (z/L)2 < 1, where z is the height and L is the Monin-Obukhov length scale, did not substantially reduce the data scatter. For thermally unstable flows, the dimensionless wind shear is expressed by the form (1+z / L)n with n = 3 / 2.
