Suggestions for revision or reasons for rejection

The newer version of the manuscript (in particular Section 3.1) appears improved with respect to the previous one, although some points should still be clarified.

MINOR POINTS:
L104: compare -> compares
L200: although not necessary, I suggest a Table to summarize the experiment setups.
L249: the choice of the radius of maximum wind as the radius to be used for the Hart diagram is not convincing. In my opinion, this represents a strong underestimation of the cyclone extension. I suggest to remove this point, or give a better motivation.
L269: weakens -> decreases
L278: … no change of the maximum wind compared to the previous period
L283, 396: … in Figure …
L325: is missing
L335: what do you mean with “neutral” wind?
Caption Fig. 10: please indicate that the figure refers to the NOCPL run
L373, 478: resulting from …
L374: precipitation areas …
L377: add “(see Fig. 5a)” and the end of the paragraph
L385: northeastwards …
L408: H is controlled …
Caption Figure 11a: which level is shown?
Caption Figure 13: (d) refers to H, thus all panels should be changed
L435: “levels closest to the 1500 m” appear contrasting with what is reported in Figure 17 caption (the size of the symbols is inversely proportional to altitude between 0 and 1000m)
L443: does the decrease in mixing ratio imply condensation and latent heating? In which way?
L491: “and there is no real PV tower around the cyclone centre”: be careful because this is not a general result, and it does not refer necessarily to cyclone of the first category. I think this sentence can make some confusion and I strongly suggest to remove it.
L492: “extending up to 800 hPa”: really, the warm core extends also in the upper troposphere; do you mean 400 hPa?
L502: … is not due exclusively to … but also to …

Short summary

A coupled, kilometre-scale simulation of a medicane is used to assess the impact of the ocean feedback and role of surface fluxes. Sea surface temperature (SST) drop is much weaker than for tropical cyclones, resulting in no impact on the cyclone. Surface fluxes depend mainly on wind and SST for evaporation and on air temperature for sensible heat. Processes in the Mediterranean, like advection of continental air, rain evaporation and dry air intrusion, play a role in cyclone development.
