Dear Dr. Aloysius,

Thank you for your interests to HESS. Both reviewers acknowledge the importance of the topic and at the same time, both raised some concerns in the methods, particularly for the aspect of bias correction and uncertainty attribution. Please keep these comments in mind when revising this manuscript and I look forward to reading a revised version of this manuscript.

Regards,
Lixin Wang

Dear Dr. Aloysius,

Thank you very much for the revision to further improve the quality of the manuscript. We consulted with the previous reviewers about the revision. Reviewer#1 is satisfied with the revision. Reviewer#2 feels that the authors have not made much effort to address the reviewer's earlier comments and the reviewer feels the earlier comments are fairly fundamental. Importantly, the reviewer thinks it is really important that these are addressed so that the HESS readership is not given misleading information about the level of confidence in climate model projections. In the current review, the reviewer#2 highlighted the places require further attention. I generally concur with reviewers' comments and look forward to a revised version of this manuscript with reviewers’ comments in mind. If the authors disagree with any of the reviewers’ comments, please provide a rebuttal letter to detail the justifications.

Thank you for your interests to HESS!

Regards,
Lixin Wang
