Reviewer 2 Report

The paper entitled “Influence of tropical cyclone intensity and size on 2 storm surge in the Northern East China Sea” is of a very interesting topic. The correlation among the intensity of the magnitude of the meteorological event and the resultant rise in sea-level is of particular interest in storm surge prediction. The paper is generally well written and well structured. It is written in good English language (as far as I can say since I am not a native speaker). In my opinion of great importance is the validation of the model results using tide measurements. Here are some suggestions that could improve the final verion of the manuscript: • A separate section titled “Study area” should be added after the “Introduction” section describing the characteristics of the Bohai Sea and the northern Yellow Sea. In fact this section could include lines 84-106. Fig 1 should have an inset map of China showing the location of the studied sea areas. • I also propose to the authors to describe, at the “study area” section, the coastal area of the studied Seas since the impacts of the storm surges affect the coastal areas. For example the coastal area is low-lying? What are the most important land uses along the low-lying (susceptible to inundation) coastal areas? • The authors should separate the methods from the results. The section “Data, methods, and validation” includes also results. This section should only describe the methods applied. • The title of the last section should change from “Summary” to “Conslusions”. • Line 38: change “the most dangerous marine disasters” with “the most disastrous marine/coastal hazards”

Reviewer 3 Report

Author of this paper uses an innovative numerical method although numerically simplified, idealized and "numerically fast" to estimate the storm sourge caused by the wind and the size (radius) of two tropical cyclones in the Northern East China Sea, using satellite data estimates to evaluate the size of tropical cyclones. The results show that their numerical approach, although simplified and taking into account only the effect of the wind and the size of the cyclone, produces consistent results with storm surge measurements.

37) add Bonaldo et al 2019

44-46) is a strong sentence. Add reference please.

73) add Ricchi et al 2019

74-76) This is a very significant and innovative affirmation, I suggest to broaden the discussion to a very innovative aspect in marine research, such as the extreme waves (Benetazzo et al 2013, Fedele et al 2013, Barbariol et al 2018, honored et al 2006, Signell et al 2005, Cavaleri et al 2016). The extreme waves are little studied and are currently studied using satellite data and we are trying to implement parametrizations for their simulation in oceanic models.

216) Are these temperature and salinity values estimated or measured?

218) Why weren't these effects included in the model?

365) Add Montuori et al 2012

378) please add reference. I do not completely agree. Today the technology allows the study of the storm surge with very complex but easy to use numerical means, like coupled atmosphere-ocean-wave models (warner et al 2012). Even operational chains have been working for years for the study and forecasting of the storm surge (as in the case of Venice lagoon and northern Adriatic sea). One example is SHYFEM model

431) By the images shown the path of the two cyclones is different. You could show a table with the hourly distances of the minimum pressure of the two cyclones in order to quantify how similar they are.

445) I would add that in the future it is also necessary to study atmospheric effects by implementing atmospheric pressure, the effect of waves etc.,in order to have a more complete point of view taking into account the non-linear interactions of these phenomena.
