Dear author,

Thank you for your new manuscript that addresses my main concerns. A just have the following minor remaining remarks:

- p.3, L 10-12: Please change: “It is easier to modify and tune the parameters in a regional configuration. Moreover, ORCA12 may benefit from the improvements of the regional configuration.” for “Moreover, it is easier to modify and tune the parameters in a regional configuration, and afterwards make the global ORCA12 configuration to benefit from the improvements of the regional configuration.”

- p.24, L. 24: remove the “).” in the middle of the line

- p.18 L 1 & 2: change “over the same period with different ENSO signals.” for “over the same period and therefore have different ENSO signals.”

-p.18 L 10-11: change “were” for “are” as the rest of the paragraph is at the present tense
