Dear Authors
Thank-you for your revised manuscript addressing the reviewers’ comments. Now I am asking just for some “Technical Corrections” (see “Comments” below) after which you should enter the paper into the Copernicus/OS publication procedure (no more intervention by myself). There will be copy-editing and you should check that your intended meaning remains.

Thank-you for publishing in Ocean Science
Yours sincerely
John Huthnance

Comments.
Page 4 line 15. I prefer “metre” spelling for unit of length. Especially here where “top meter” could be read as the top instrument on a mooring. Napoleon defined it so there is a strong argument for French spelling as well as avoiding ambiguity. [Also page 17 line 7 and maybe elsewhere]
Page 7 top. Referee 1 asked about boundary forcing. I think your answer with respect to variables is here. However, to me this looks like over-prescription unless you qualify the statement. Especially, prescribed velocity, sea-surface height and density (from T and salt) may not be compatible for ROMS, and this can be especially important in a small sea area.
Referee 2 comment on surface roughness. I am fairly sure that I agree with you that two different approaches [section 2.3.2, page 7 line 23; Appendix equation (A2)] are appropriate. As I read it these concern the sea and the air respectively. Regardless of questions of form drag, if the effective stress were the same, the friction velocity would be the same but certainly the profiles would not be “mirror images” of each other so clearly values of z0 have to differ. However, I think it would be appropriate to put something in your text (maybe “only” in the Appendix) as a response to the Referee, since their comment has been made, so that your paper is self-contained. Your words, not mine!
Page 8 equations (1) and (2). You have “p” in (1) but “ϕ” in (2). Are they the same or how are they related?
Page 10 line 14. “less” implies a comparison, but with what? Maybe “slightly”?
Page 22 line 8. Better “. . depth reaches values greater than 100 m . .”. [“higher” and “depth” do not go well together.]
Page 22 lines 8-10. You do not say why this sentence is relevant. Please say. [I guess it is because the eastern coastal areas of the Irish Sea are very shallow.]
