Reviewer n. 2 has concerns about the interpretation of several parameters introduced by the authors regarding the wind farm efficiency, the contributions to it from internal versus external wakes, and the treatment of the power coefficient as calculated in a previous study as nearly ideal. I suggest that the authors take seriously into account the concerns of the reviewer and consider either removing some of the metrics, or reformulating them in a different way. Either way, this effort is technically not major, but significant enough that I will want the same reviewer to review the manuscript for a third time before reaching my decision.

Reviewer #2 still had some concerns on the interpretation of Cp/Cp,Nishino and requested further clarifications. I agree that the revised sentence (in blue) did not clarify, but rather added confusion. What other mechanism, then, caused the reduction of downstream power, if not the reduced wind speed from the upstream turbine wakes?
