Abstract: In order to have a complete description for the diurnal cycle for the atmospheric boundary layer considering different thermodynamical regimes (convective, stable, residual and neutral), is necessary to describe a model for the growing of the convective boundary layer. This is the focus on this work. Starting from the spectral form of the turbulent energy equation, the Pao's parameterization is employed to represent the interaction among small and large eddies, instead of Heisenberg's approach [3] (used in previous paper [1]). The Pao's approach has more physical support than Heisenberg's assumption, and the former is used to derive a model for the growing of the convective boundary layer.
