Measurements were made of mean and fluctuating velocities and temperatures and of the diffusing plumes. When presented in a dimensionless coordinate system based on the buoyant heat flux and the thickness of the convective layer, the data appear to be consistent with available data from field studies and water-tank simulations and exhibit a unique pattern of diffusion which is related to the nature of the thermals and the downdrafts within the convective boundary layer.reportsengCopyright and other restrictions may apply.
