Hi Shima,
I just noticed your paper and I only skimmed through it briefly. However, I wanted to make a very minor comment: A few months ago, a student of mine and I published a paper on a very similar topic, using MERRA-2 to describe the changes in ozone over the Arctic and the Tropics in response to SSWs and Vortex Intensification events. Here is the reference:
Hong, H. J., and T. Reichler, 2021: Local and Remote Response of Ozone to Arctic Stratospheric Circulation Extremes. Atmos. Chem. Phys., 21, 1159-1171.
Maybe, you could cite our paper in your literature review.
With kind regards,
Thomas Reichler

  We are thankful to both reviewers for their thorough comments. We have added some paragraphs to the introduction to better clarify previous studies that are relevant to this manuscript and to elucidate remaining research questions that this study focuses on. A few graphs have been updated to have higher resolution and to include statistics, as suggested by the reviewers. We have used more clear language to highlight the novelty and main findings of this study. We applied most of the reviewer’s suggestions and provide justification for those that we did not include. We believe that the quality of this manuscript has been greatly improved by these reviews. Our detailed responses are attached here.

Short summary

Large-scale atmospheric circulation has a strong influence on ozone in the Arctic, and certain anomalous dynamical events, such as sudden stratospheric warmings, cause dramatic alterations of the large-scale circulation. A reanalysis model is evaluated and then used to investigate the impact of sudden stratospheric warmings on mid-atmospheric ozone. Results show that the position of the cold jet stream over the Arctic before these events influences the variability of ozone.
