Round 1

Reviewer 1 Report (Previous Reviewer 2)

Thanks to the authors for addressing all of my comments.  I have no more comments, and  I recommend the paper be accepted for publication.

Reviewer 2 Report (Previous Reviewer 3)

Authors addressed all the concern. It can be accepted in the present form.

This manuscript is a resubmission of an earlier submission. The following is a list of the peer review reports and author responses from that submission.

Round 1

Reviewer 1 Report

The manuscript is reasonably well-written and the experiment is interesting. However, Remote Sensing is not the right journal for this manuscript as there are no meaningful remote sensing issues discussed. I encourage the authors to withdraw and resubmit to Atmosphere or JMSE.

Title: Impact of global warming on tropical cyclone track and intensity: a numerical investigation

Authors: Zhihao Feng, Jian Shi, Yuan Sun, Wei Zhong, Yixuan Shen, Shuo Lv, Yao Yao, Liang Zhao

Summary: This is an interesting study on the important topic ofhow TC track and intensity respond to changes in the oceanic and atmospheric environment under different carbon emissions.The simulation of three experiments were conducted by using the COAWST modeling system under Historical (SSP245/SSP585) emissions. They found that the simulated TC tended to migrate poleward and TC intensity increased with carbon emissions, yet the relationship between the increase of TC intensity and global warming is not linear.The involved mechanisms were also revealed.However, I was wondering the robustness of the sensitivity experiments on account of the initial TC location and intensityin the TC Bogus scheme. Dothe initial location and intensity of tropical cyclones affect the results of model tests? For example, Figure 4 showed that the tropical cyclone initial location located at north of 20N latitude. Whether this location is too far north. In addition, whether the test results will be different if the tropical cyclone genesis over the South China Sea. Overall, the MS is well written and clearly demonstrate the work and the results. The investigation advances our understanding about the effect of global warming on TC track and intensity. Based on my evaluation and the points above, I recommend that minorrevisions are needed before publication.

Recommendation: Minor Revision

 

Specific comments:

1.     L199-200: “However, differences appear during mature and decay stages of TC.” It is hard to follow this statement. Please clarify.

2.     Figure 6: Why wind vector patterns are the same in the three carbon emissionsat the 6 hour after the model start? Please clarify.

3.     Figure 7: It is confusing that the minimum SLP of TC do not match the maximum wind speed at 10-m height in historical emissions at 48-60H. Please clarify.

4.     L284:“In the development of TC, ocean environment serves as a key determinant.” I think it should be better to change as “one of the key determinants”

5.     Figure 8: The reasons that it was calculated between SST 1 day after the LMI moment and the initial SSTshould be provided and it would be helpful for readers.

Reviewer 3 Report

In work entitled " Impact of global warming on tropical cyclone track and intensity: a numerical investigation" by XYZ et al., the Authors demonstrated the response of track and intensity on changing oceanic and atmospheric environment conditions for three carbon emissions, which is a very interesting topic. I have read the manuscript, and I saw that its results fall within the scope of the journal.  However, need some minor modification and reformulation of sentences before its eventual acceptance.

Abstract:

Comment:1 Overall, the abstract is well written and summarizes the findings of the studies. However, has some scope for improvement to improve readability.

Comment:2 Authors have stated the demonstrated the response of  3 different. three carbon emissions, please add some findings in this context in the Abstract.

 

Comment:3 Line-11-12 “Relatively little is known about the impact of global warming on the tropical cyclone (TC) track and intensity by reasons of data inhomogeneity in remote sensing and large natural variability over a relatively short period of observation”. Please rephrase the sentence. In this Era, ample number of effort focused on the tropical cyclone in the text of global warming. Just few example,

Comment:4 line:21-24 “As a result, TC intensity increases with carbon emissions. However, the increase of TC intensity is notably smaller than that according to maximum potential intensity (MPI) theory, and the increase of TC intensity becomes slow with the increase of carbon emissions.” Please rephrase the sentence for better clarity.

Comment:5 Authors have demonstrated the impact of ocean and atmospheric conditions on cyclone (considering all cyclone: very severe to cyclonic storm), However, a previous study (for example, Tiwari et al., 2021) have a different response for the very severe cyclonic storm, severe cyclonic storm, and cyclonic storm. If possible, please make a similar analysis or make some comments in the text citing the previous study.

Comment:6 Introduction needs to add recent references and includes some discussion of the motivation of the study at the end of the introduction.

Comment:7 Please increase the line width and text font in Figure 7. Similarly, in Figure 8, increase the line width and marker size showing the TC center.
