Analysis of Extreme Rainstorms Associated with Tropical Cyclone Rammasun (2014) over Guangxi Province of China
Round 1
Reviewer 1 Report
The precipitation characteristics associated with a Tropical cyclone during it making landfall are complicate. Authors try to interpret them from large and mesoscale or dynamic and thermodynamic. The logic is not clear.Some major comments to be addressed by authors.
1. How did authors identify the large-scale and mesoscale messages in the text? Such as Why was the Fig. 4 considered to represent a Large-scale distribution. A wide range shown does not mean a large-scale. Same, a small range shown (such as Fig.5, All factors in section 5) does not do mesoscale characteristics.
2. Some statements in the text are somewhat arbitrary. Some analyses are lack of basis, such as
(1) L196-201：How and where does the SAH contribute to the convention development?
(2) L201-202: Why did TC Rammasun (2014) caused an eastward retreat of WPSH, while not the WPSH affect the TC activity? The Figure only shows the results, but not be used to interpret the cause and effect.
(3) L212: In Fig.4b, I do not find the 588 dagpm stretched west to central Guangdong province.
(4) Fig.5 title indicates the contour means divergence, I do not find it.
(5) Why was not the vertical velocity to directly analyze vertical motion. Dynamic and thermodynamic factors shown in Fig. 7 can be available to explain vertical velocity. The unstable energy should be calculated by local Radiosonse data, not qualitatively description given by authors (such as in L296-297, L325-327).
3. The writing is difficult to understand and needs substantive improvement, such as
(1) Title can be revised into: Analysis in extreme rainstorms associated with tropical cyclone Rammasun (2014) over Guangxi province of China
(2) The statement in L10-11 “three extreme rainstorms centered at Hepu, Fangcheng and Lingshan in Guangxi”. The Fig. 1 shows that there are three heavy rainfall centers in Guangxi province not three extreme rainstorms.
4. I do not understand what major difference among three conceptual models shown in Fig.9 a,b,c

Reviewer 2 Report
A mesoscale and highscale analysis of the extreme rainstorms produced by Tropical Cyclone Rammasun in the year 1409 is performed.
The motivations for this research are described in little detail. Indeed, certainly, as the authors claim, conceptual models with distinct regional characteristics configured at large and mesoscale should play a significant role for the numerical predictions of heavy precipitation, but it is necessary to specify how they allow to increase the accuracy of the predictions and what are their critical points, for example the growth of the complexity of the model which depends on a large number of parameters necessary to characterize the study region. Furthermore, it is necessary that the authors in the introduction briefly highlight how they deal with these critical points in the proposed conceptual model.
Section 2 should contain an outline and a detailed description of the conceptual model used in the analysis. Authors briefly describe the data used (section 2.1) and the orographic precipitation equation employed in the calculation of the orographic precipitation rate (section 2.2). They do not describe their model processes implemented from source data for mesoscale and large-scale analyes.
In sections 4 and 5, before the results, the methods used in the analyzes must be described. For example, for the production of the wind intensity distribution maps in Fig.4 the spatial modeling methods used must be described. The same is true for the results shown in Fig.s 5 and 6 and for the spatial distributions shown in Fig.s 7 and 8.
The proposed conceptual model must be presented and described before the description of the results and not in the concluding section. Furthermore a thorough discussion of this conceptual model needs to be added.

Reviewer 3 Report
The publish of paper is valuable for regional disaster prevention. Some revision is preferable before the publication.
Revision Points:
1) TC Rammasun is the strongest one in the target region but is little bit an old record. There are several TC which caused the devastated hazards in the south China recent years. If possible, please introduce the general information of TC hazard in southern China including the target area these days,
2) Line 43; What is the low-level jet? Please add the detail explanation about the low-level jet.
3) Figure 1; Please indicate the [unit] at the contour bar.
4) Line 118; Please explain about the geopotential height.
5) Line 157; “Guangxi” is the province name? If so, please indicate that Guanxi is one of the provinces of China.
6) Line 159; Please input the year.
7) Figure 2; Please indicate the [unit] at the color contour bar.
8) Line 210-211; Please explain about “SAH” and “WPSH”
9) Figure 4; Input [unit] under the color.
10) Figure 5-8; Please put [unit] under the color bar:
11) Line 334: Where is the Wuzhi Mountain?

Round 2
Reviewer 1 Report
Authors did some revisions according to comments. Here one suggestion: The title of 5.1 is inconsistent with contents, instead of dynamic and thermodynamic analyses. "triggering mechanism' word in the text is better removed.
