I wish to thank both referees and B.Cagnoli for their valuable comments.
Following the comments of the reviewers and the interactive discussion, the paper needs a major revision.
In general, the answers provided by the authors are satisfactory, and I kindly invite the authors to provide a new version of the manuscript for a further review.
Referee #2 (S.Charbonnier) also provided an annotated pdf file with additional minor corrections. Please, also note a typo in Table 1 (the dimension of gravity acceleration is m/s^2).

The revised manuscript accounts for the suggestions of the reviewers and
is strongly improved. I consider the manuscript ready for publication.

I suggest just a minor correction: symbol "Delta Tw" appearing in
eq. (1) is referred as "the required thermal energy to vaporize
water". Later, at page.6, line 4 the same symbol indicates "The
temperature gradient from surface to the dome interior". Moreover,
the difference of temperature 200-800 C, technically, is not a
"gradient" but a "temperature difference" between the surface and the
dome interior. Please, can you check these points?
