Questions and Answers
Questioner Name: Yosef Levitin
Q: What source of surface heat flux of 100 Wm−2?
A: We prescribe during the whole simulation in both mixed-layer and large-eddy simulation models a constant surface sensible heat flux (SH) of 0.1 mKs−1 for the REF experiment. For UNI and TOP the SH is reduced to 0.08 mKs−1 due to the aerosol shadowing at the surface.
Q: Do you use different models for rural and urban areas?
A: We do not have land-use or surface heterogeneity. We consider a flat and homogeneous surface for all the experiments with a constant and prescribed surface sensible heat flux.
Questioner Name: Peter Buitjes
Q: Is there an explanation why the uniform case height of the ABL goes faster to equilibrium than the aerosol-cases?
A: Since the aerosols initial condition in the UNI is already uniformly distributed in the mixed-layer, the equilibrium is reached around 2 h before than the TOP experiment. In addition, the aerosol layer in the TOP experiment disturbs more the inversion layer jump (Fig. 19.2b) and as a consequence additional time is needed to reach a new equilibrium state.
