Abstract
Coherent vortex and flux structures in shear-driven PBL (SPBL) flows were studied by large eddy simulation (LES) to gain an insight into the dynamic processes of turbulence production in PBL flows. Coriolis force and capping inversion, which prohibits the growth of SPBL height, are included in the LES model. We investigated the dynamics of the coherent structures in SPBL, and found that surface roughness has a strong impact on the strength and size of these structures. The drag coefficient may be an important parameter characterizing the dynamics of SPBL structure. (Author)
