Abstract:
The planetary boundry layer (PBL) is characterized by different thermodynamics
conditions: neutral, stable, and convective boundarylayers. Few studies in
the literature are dedicates to the transitions layers.
The transition phase from neutral boundary layer to convective boundary
layer(CBL) will be presented.The characteristics of the turbulent kinetic
energy (TKE) during the growth phase of the CBL are analyzed with the
help of 3D analytical spectral model. The precision and characteristics
of the TKE spectra generated by analytical model are compared with
data obtained by the Large-Eddy Simulation (LES) model for three
different levels in the vertical.
The analytical model agrees fairly well with LES results. |
