Abstract：An investigation was carried out for the weather conditions facilitating acid rains based on the reasonable model outputs from the MM5 mesoscale model. The acid rain event of interest occurred in the Hengshan region of Hunan province on 24 March 2009. This investigation revealed that a stable planetary boundary layer (PBL) with poor diffusion conditions played an important role in the acid rain event. The topography in the Hengshan region maked the relatively low layer suffer from the cold air earlier than the relative high layer, leading to the formation of the stable PBL. The stable PBL in the Hengshan acid rain case was thinner than that in a Guangdong province acid rain case.
