Starting from the evolution equation for the turbulent energy density spectrum (EDS), we develop a new model for the growth
of the Convective boundary layer (CBL). We apply dimensional analysis to parameterize the unknown inertial transport and convective
source term in the dynamic equation for the three-dimensional (3-D) spectrum and solve the 3-D EDS equation. The one-dimensional
vertical spectrum is derived from the 3-D spectrum, employing a weight function. This allows us to select the magnitude of
the vertical spectral component for the construction of the growing 3-D EDS. Furthermore, we employ the vertical component
of the energy spectrum to calculate the eddy diffusivity (required in dispersion models). Currently there are no available
experimental data to directly verify our EDS model. 相似文献
