Dear Dr Wang,

Thank you for submitting your manuscript the Earth System Dynamics. Now we have received two referees' assessment on your manuscript submitted to ESD. After reading the referees' comments and the reponse provided by the authors, I decide to reconsider this manuscript for the possible publication after major revisions to be made. The authors should address referees comments seriously point by point. We will send the manuscript back to the referees in the next around of review.

Best Regards!
The Editor

Dear Authors,

We have sent this manuscript to review by orginal reviewers in the last around of review and an additional reviewer. Based on the comments, I decide to send back to the authors for major revisions on this manuscript. As pointed by referee #2, the authors should improve the English of this manuscript substantially by an English native speaker before the manuscript can be considered to publish in the ESD.

Best Regards!
The Editor
