Abstract
By assuming that the dispersion time scale in the convective boundary layer is “infinite,” we have derived a simple relationship between the ground-level concentration and the probability density function of vertical velocities at source height. This formulation yields results that compare favorably with the water-tank experiments of Willis and Deardorff (1978).
