The pith

Risk assessments overlooking compound typhoon hazards in South Korea may produce ineffective mitigation for coastal infrastructure.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper reviews available data, models, and methods for evaluating both single and combined typhoon effects including storm surge, wind, and rainfall along South Korean coasts. It focuses on adapting and extending established North Atlantic assessment techniques to fit the local setting, with examples drawn from multiple sites. A sympathetic reader would care because future climate change may increase these risks, and missing the interactions among hazards could leave protective measures inadequate.

Core claim

This study seeks to identify and evaluate the available data, models, and methodologies for assessing both individual and compound typhoon-induced hazards in South Korea, with particular effort devoted to exploring how established approaches from the North Atlantic region can be adapted, integrated, and extended for application in the South Korean context, illustrated through analysis of multiple sites.

What carries the argument

Adaptation, integration, and extension of North Atlantic typhoon hazard assessment approaches to evaluate compound impacts of storm surge, wind, and rainfall in the South Korean coastal setting.

Load-bearing premise

Sufficient relevant data, models, and site-specific information exist or can be readily obtained to support adaptation of North Atlantic methods without major unaddressed regional differences in typhoon behavior or coastal geography.

What would settle it

Direct comparison of observed compound hazard impacts from recent South Korean typhoons against predictions from the adapted North Atlantic methods showing large systematic under- or over-estimation that cannot be explained by data limitations alone.

read the original abstract

Tropical cyclone-induced coastal hazards can significantly damage coastal infrastructure, and these risks may intensify under future climate change. As a result, there is increasing interest in conducting comprehensive assessments of coastal hazards-including storm surge, storm wind, storm rainfall, and their combined impacts-associated with tropical cyclone events. Risk assessments that overlook the compounding nature of these hazards may lead to ineffective or insufficient mitigation strategies. This study seeks to identify and evaluate the available data, models, and methodologies for assessing both individual and compound typhoon-induced hazards in South Korea. Particular effort is devoted to exploring how established approaches from the North Atlantic region can be adapted, integrated, and extended for application in the South Korean context. Multiple sites across South Korea are analyzed to illustrate the strengths and limitations of these methods.

Desk Editor's Note private letter to a colleague

This is a regional review that catalogs data and models for typhoon multi-hazards in South Korea and discusses adapting North Atlantic methods, but it does not show that the adaptation holds up quantitatively.

read the letter

The main point is that this paper reviews existing approaches to typhoon-induced hazards like surge, wind, and rainfall for South Korea and explores how North Atlantic compound assessment methods might transfer. It does not introduce new techniques, derivations, or fresh empirical results. Instead it maps available resources and picks sites to illustrate where current methods might need adjustment for local conditions. That practical focus is its main strength. It correctly flags that overlooking compound effects can weaken mitigation plans, and it pulls together sources that local planners could use without starting from zero. The site-by-site discussion gives a sense of where data gaps or model limitations show up in the Korean context. The soft spot is the transferability claim. Typhoon tracks, intensification rates, and coastal features such as Yellow Sea tidal flats and indented bays differ from North Atlantic settings, so the joint-probability statistics and model skill may not carry over directly. If the paper only lists models and data sources without running explicit comparisons or showing calibrated outputs for Korean sites, the adaptation argument stays preliminary rather than demonstrated. The abstract and structure suggest the work stays at the level of assessment rather than validation. This paper is aimed at coastal risk managers and engineers working on South Korean infrastructure. A reader who needs a starting point for local multi-hazard planning will get useful pointers on data and methods. Someone looking for new science or broadly applicable advances will not find much. It deserves peer review because the topic addresses a real planning need and referees can require the quantitative checks that would make the adaptation claims more solid.

Referee Report

2 major / 2 minor

Summary. The manuscript reviews available data, models, and methodologies for assessing typhoon-induced individual and compound coastal hazards (storm surge, wind, rainfall) in South Korea. It focuses on identifying how established North Atlantic approaches can be adapted, integrated, and extended to the South Korean context, with analyses of multiple sites used to illustrate the strengths and limitations of these methods.

Significance. If the adaptation framework is shown to be viable with appropriate regional adjustments, the work could meaningfully advance compound-hazard risk assessment in the Northwest Pacific basin. It correctly emphasizes that overlooking compounding effects risks ineffective mitigation, and the site illustrations could provide a practical starting point for South Korean coastal planning under climate change.

major comments (2)

[Site analyses] Site analyses section: The paper catalogs data sources and notes general limitations for South Korean sites but does not perform quantitative comparisons of typhoon track statistics, recurvature frequency, or rapid intensification rates against North Atlantic benchmarks. Without such calibration, the claim that North Atlantic joint-probability and surge models can be directly extended remains unsupported given documented basin differences.
[Adaptation discussion] Adaptation of North Atlantic methods: The discussion of transferring storm-surge and compound-hazard frameworks does not address explicit adjustments for Korean coastal morphology (Yellow Sea tidal flats, indented bays, East Sea exposure). These features can materially change surge amplification and wave setup relative to typical North Atlantic coastlines, requiring at least a pilot comparison to substantiate transferability.

minor comments (2)

[Abstract] The abstract states the study goals clearly but could briefly summarize the main outcome of the site analyses (e.g., which methods transferred most readily).
[Throughout] Ensure consistent use of terminology for 'compound' versus 'multi-hazard' throughout; the two are used interchangeably in places, which may confuse readers.

Referee: [Site analyses] Site analyses section: The paper catalogs data sources and notes general limitations for South Korean sites but does not perform quantitative comparisons of typhoon track statistics, recurvature frequency, or rapid intensification rates against North Atlantic benchmarks. Without such calibration, the claim that North Atlantic joint-probability and surge models can be directly extended remains unsupported given documented basin differences.

Authors: We appreciate this feedback. However, the manuscript does not assert that North Atlantic models can be directly extended; the abstract and introduction explicitly state the goal of exploring how these approaches 'can be adapted, integrated, and extended' for the South Korean context. The site analyses are intended to illustrate strengths and limitations through available data rather than to provide a full climatological calibration. Quantitative comparisons of track statistics and intensification rates are valuable but fall outside the scope of this methodology-focused review. We reference basin-specific differences where relevant and can expand the discussion of these differences in a revised version if required, but we do not believe such additions are essential to support the paper's core objectives. revision: no
Referee: [Adaptation discussion] Adaptation of North Atlantic methods: The discussion of transferring storm-surge and compound-hazard frameworks does not address explicit adjustments for Korean coastal morphology (Yellow Sea tidal flats, indented bays, East Sea exposure). These features can materially change surge amplification and wave setup relative to typical North Atlantic coastlines, requiring at least a pilot comparison to substantiate transferability.

Authors: We agree that coastal morphology is a critical factor in surge and wave modeling. The current text notes the need for regional adjustments but could benefit from more specificity. In the revision, we will expand the adaptation discussion to explicitly address how features like the Yellow Sea's tidal flats may dampen surge heights relative to steeper Atlantic coasts, the potential for enhanced setup in indented bays, and the distinct exposure on the East Sea. We will draw on relevant literature for these adjustments and include recommendations for pilot studies, though a full quantitative pilot comparison is not feasible within the present study but will be suggested as an important direction for future research. revision: partial

Circularity Check

0 steps flagged

No circularity: literature assessment with external benchmarks

full rationale

This paper performs an external assessment of existing data sources, models, and North Atlantic methodologies for typhoon hazards, then explores their adaptation to South Korea through site analyses. No original equations, parameter fits, or predictions are described that could reduce to the paper's own inputs by construction. The central claim rests on cataloging and evaluating independent literature rather than any self-definitional loop, fitted-input renaming, or load-bearing self-citation chain. The work is therefore self-contained against external benchmarks with no detectable circular steps.
