Abstract

In a convective boundary layer (CBL) over an urban patchy surface pattern, turbulent structure may have a strong response to the surface forcing induced by the patchy pattern of sensible heat flux caused by different landuse type. It is not clear that the dispersion of a passive plume emitted into such a boundary layer will have different characteristics from that emitted into a CBL over a horizontally homogeneous surface such as a typical uniform rural area. The present study aims to investigate the case by using large-eddy simulation (LES) with a focus on the mean plume height.
