Suggestions for revision or reasons for rejection

I read the revised version carefully and I found the manuscript to be improved. Most of my comments and suggestions were adequately addressed, although I find that English could be still improved. Nevertheless, the text is understandable and the messages are clear. I only have some minor languages comments on the corrections done by the authors.

Line 63: "medicanes"

Line 65: "delta"? This could become more precise?

Line 67: "most of the medicane characteristics moderately intensify". Either be more precise or remain to a more general remark, e.g. the cyclone is fairly unchanged.

Line 68: what is the "maximum depression of sea level pressure (SLP) minimum"?

Line 81 "insights into", what is the "anthropogenic warmer ocean"?

Line 91: "amounts"

Line 93: Please remove "nations".

Lines 93-99: I suggest to rephrase. A high number of cyclonic storms may occur during a year. However, it is only few of them that qualify as medicanes mainly due to phenomenological criteria such as cloud-free "eye". I suggest to remove Lines 97-99.

Line 101: What similarities are you referring to? If this is the "eye" formation then I suggest to better articulate with the previous paragraph.

Line 106: This temperature range is not homogeneous in the Mediterranean Sea. IT is my impression that 23 degrees is rarely reached in the areas where medicanes are more frequently developed.

Line 110: "triggered" instead of "preceded".

Line 122: I would say that the case study of Fita and Flaounas (2018) is not relevant to tropical transition. This is indeed contradictory with statement in line 275.

Lines 127-130: I do not understand this part.

Line 131: "...some cases... involves tropical transition". Please provide details and references on the cases where tropical transition was relevant and how TT was involved.

Line 170: What tropical cyclone-like characteristics are you referring to?

Line 189: It seems quite odd to start figures narrative with a reference to supplement material.

Line 312: Here and throughout the manuscript, please be more careful when describing the processes. The development of the cyclone "can be linked" to convection which in turn can be favoured by air-sea exchanges.

Line 316: "Decrease" instead of "reduce".

Line 317: Awkward phrasing.

Line 320-322: I am not sure I understand this phrase. Is by "grid box" meant a grid point? If so, why this value is representative for the cyclone processes if it only refers to a very localised peak?

Line 324: "enhance evaporation more effectively". This is awkward phrasing. Is it meant that warmer SSTs may favour evaporation in the other studies, compared to Rolf here?

Lines 333-334: I am not sure that I understand the definition of MWS. Why it is not just the 95th percentile of wind speed of all grid points within an area of 250 km from cyclones centre?

Line 336-337: How can two different fields with different units vary consistently? Do you mean that they both increase and decrease in phase?

Lines 427-432: There are multiple repetitions here. Please rephrase to clarify the content.

Line 468: what is meant by "similar"? Is it meant that both take place in the same time?

Line 469-472: "development of a deep warm core is not as strong...". What is meant by "strong development"?

Line 474: Perhaps "present climate" instead of "present day"?

Line 487: Either be more precise, or remove this phrase so that the S2 is not necessary for understanding the content.

Line 550: what is meant by "activated efficiently"?

Line 622: I am not sure what is meant by "source of medicanes".

Line 627: Please be more precise on "some impact". Is it fair to say that the background has a limited impact on the development of the medicane?

Short summary

This study investigated one case of a tropical-like cyclone over the Mediterranean Sea under present and future climate conditions with a regional climate model. A pseudo global warming (PGW) technique is employed to simulate the cyclone under future climate, and our simulation showed that the cyclone is moderately strengthened by warmer climate. Other PGW simulations where only ocean and atmosphere are warmed reveal the interesting results that both have counteracting effects on the cyclone.
