Abstract

Atmospheric aerosol plays critical roles in suppressing planetary boundary layer (PBL) and deteriorating air quality. However, comprehensive understanding on how aerosol optical properties (absorption and scattering) affect PBL remains lacking. Utilizing a large‐eddy simulation model incorporated with in situ observations, we demonstrate distinct impacts of absorption aerosol on PBL development when it is present below (stove effect and promotion) or above morning residual layer (dome effect and strong inhibition) and similar inhibition umbrella effects of scattering aerosol on PBL regardless of its vertical locations. There exists a transition height, above which absorption aerosol is more effective in suppressing PBL and below which scattering aerosol dominates the suppression. This height is highly related to the height of morning residual layer. Aerosol stove, dome, and umbrella effects enrich our knowledge on aerosol‐PBL interactions and the latter two can be interpreted as “double inhibitions” in promoting haze episodes in the North China Plain.
