Quasi - stationary state of convective boundary layer over heterogeneous flat surfaces
2.
Wavelengths or scales of surface heterogeneity are less than 20km . simulation results show that cbls do reach a quasi - stationary state correspondent to specified surfaces , after a long enough evolution . in this transition process and after that , horizontal statistics , i . e . mean potential temperature and vertical heat - flux , show profiles little differences to those over homogeneous flat surface . main effect of surface heterogeneity is to increase kinetic energy in cbl and the increase concentrates in the direction of surface heterogeneity . the time of cbl spent to reach its first peak of mean kinetic energy ,
