The manuscript "Impacts of Atmospheric Circulations on Aerosol Distributions in Autumn over East China: Observational Evidences" by Xiao-Yi Zheng et al. addresses the influence of atmospheric circulations on aerosol distributions in autumn over East China. The authors thank the Editor and Reviewers for their comments and have revised the manuscript accordingly. The revised manuscript includes detailed responses to the reviewers' questions. The Reviewer #1 raised several issues, including the meaning of SD in Figure 1b, the need for more explanations on annual variations of AOD, and the relationship between atmospheric circulation and air quality. The authors clarified that the SD in Figure 1b refers to the standard deviation of AOD. They also explained that annual variations in AOD are influenced by factors such as fire emissions and wind speed. The authors also discussed how different atmospheric circulations can lead to different diffusion conditions, and how temperature may influence AOD distribution. The authors also mentioned the importance of emission inventories in understanding the relationship between AOD and emission distribution. The manuscript also discusses six atmospheric patterns that were summarized for polluted episodes, and the authors have used quantified indexes to compare the differences among the six types. The authors also added vertical cross sections of vertical velocity and divergence of wind to explain the influence of circulation. The revised manuscript includes detailed discussions on these topics. The authors also referenced several studies to support their findings. The manuscript is a research article published in the ACP journal.The manuscript "Impacts of Atmospheric Circulations on Aerosol Distributions in Autumn over East China: Observational Evidences" by Xiao-Yi Zheng et al. addresses the influence of atmospheric circulations on aerosol distributions in autumn over East China.
