Summary: In this study, it was found that the interannual variability of observed storm surge levels can be explained and predicted through a process-based study in Hong Kong. The impact of El Nino-Southern Oscillation on storm surge levels was found to be influenced by tropical cyclones (TCs) and other forcing factors. After removing the ENSO effect, the occurrence frequencies of local and remote TCs were responsible for the remaining variability in storm surge levels. The statistical prediction model formed by ENSO and TC indices showed good skill in predicting extreme storm surge levels.

Summary: The incidence of climate-related disasters is increasing, requiring intensified anticipatory action. This study proposes a dependence-informed sampling scheme to reduce the complexity of the problem and select scenarios with the highest cumulative likelihood of potential impact. Analysis of historical tropical cyclone records near the coast of Texas demonstrates the usefulness of this approach in improving hazard risk assessment efficiency and providing reliable information at a lower cost.

Summary: The study found that ocean tides and storm waves have instantaneous, rapid, and synchronous effects on coastal groundwater levels, especially in the Ganges river mega-delta, one of the world's most extreme climate-affected regions. Machine learning techniques can accurately predict the rise of groundwater levels in deeper aquifers during ocean wave surge events, but are unable to quantify the changes in shallower groundwater levels during storm events.

Summary: A new surrogate model, the C1PKNet, is proposed in this study to rapidly predict peak storm surges across an extensive coastal region from time-series of tropical cyclone conditions. The model shows great performance in the Chesapeake Bay area and can enhance coastal resilience by providing rapid storm surge predictions.

Summary: This paper proposes a method to estimate design water levels and wave conditions using synthetic tropical cyclone tracks and wind fields, which is particularly important in regions with limited historical tropical cyclone events. The results show that synthetic tracks provide reliable estimates of the first-order hazard (wind speed) and can be used to compute the second-order hazards (storm surge and waves). Comparisons between historical and synthetic tracks demonstrate that the use of synthetic tracks leads to more accurate extreme value estimates and reduces the uncertainty in estimation.

Summary: The South Pacific region is vulnerable to extreme total water levels due to the lack of wide continental shelves that can dissipate waves. This study examined the waves and storm surge induced by severe TC Harold in 2020 on Tongatapu using advanced hydrodynamic and wave models. The contributions of winds, atmospheric pressure, waves, and wave-radiation-stress-induced setup to extreme total water levels were analysed. The suite of models used in this study can support the Tonga Meteorological Service Tropical Cyclone Early Warning System.

Summary: The February 2014 extratropical cyclonic storm chain caused significant damage to the English Channel and Dawlish, resulting in the closure of a main railway line for two months and substantial economic loss. However, the disaster management was successful, with immediate actions taken to save lives and property. Analysis revealed that wave impact force, along with wave reflection off a vertical wall, were the key factors contributing to the damage.

Summary: In a region like the Northern Indian Ocean basin, the study focused on the non-linear wave-wave interactions during cyclonic conditions by incorporating pre-existing wave effects into the numerical model. The results showed that using wave boundary conditions improved the agreement between simulated wave parameters and observed field data, as well as correlated well with in-situ measurements of surge.

Summary: This study presents a method to analyze storm surge scenarios using a large ensemble forecast of tropical cyclones. The Pareto-optimized solutions from the ensemble forecast can efficiently describe potential worst and minimum storm surge scenarios, providing valuable insights for decision making. The analysis of meteorological variables in the ensemble members can help understand the impact of tropical cyclones on predicted storm surge scenarios.

Summary: This study focuses on the parametric modeling of tropical cyclone (TC) wind fields and their applications in storm tide modeling. The results show that a simple empirical background-wind model combined with the rotation and scaling of the TC motion vector can capture the observed surface wind asymmetry effectively. Furthermore, a physics-based complete wind profile model connecting the inner core and outer region performs better than a wind analysis dataset for symmetric wind fields.

Summary: The future coastal flood hazard will be influenced by both tropical cyclone change and relative sea-level rise. Correlations between sea-level rise and tropical cyclone change suggest that neglecting their joint influence may lead to underestimation of future flood hazard.

Summary: This study demonstrates a significant correlation between TC pre-landfall forward speed and maximum storm surge height, with the coastal morphology playing a determining role. Fast-moving TCs amplify storm surges along open coastlines but reduce their impact in semi-enclosed bays. These findings highlight the need for improved storm surge predictions and more precise early warnings for emergency management personnel.

Summary: This study found that storm surge heights have increased in coastal regions of Central Japan, especially Tokyo Bay, over the past 20 years. This increase is attributed to the stronger and larger tropical cyclones during landfall, as well as the increased frequency of cyclones with northeastward tracks. The positive correlation between surge heights and a hazard index further supports these findings.

Summary: This study investigates the characteristics of partially submerged landslide-tsunamis through laboratory experiments and develops a predictive equation to estimate their heights. The results show that wave amplitude, period, celerity, and wavelength do not vary significantly according to propagation angles, but wave dispersion has a significant impact on the propagation process. The volume of a landslide has a greater effect on the height of a partially submerged landslide-tsunami than other parameters.

Summary: This study investigates the effectiveness of coastal forests in reducing tsunami-related casualties using simulation models. The results show that coastal forests can reduce casualty rates, but constructing a dyke that can withstand tsunami overflow is more effective. Furthermore, combining coastal forests and a dyke is more effective than using either measure alone.

Summary: Including sea-level rise (SLR) projections in coastal adaptation planning is crucial, but only 72% of coastal practitioners currently utilize them, with lower utilization in developing countries. There is no global standard in the use of SLR projections, but countries with histories of adaptation and consistent national support show greater assimilation of SLR projections.

Summary: Wind and atmospheric pressure are the main factors in generating storm surges caused by tropical cyclones. However, meteorological models can sometimes have deviations from actual observations. This study proposes a method called GWB-M that modifies both wind and pressure fields in meteorological models based on the dynamic relationship between wind and pressure in typhoons. The GWB-M method is assessed using a storm surge hindcast of Typhoon Faxai in 2019 and shows improvements in wind speed, sea level pressure, and accuracy in capturing maximum sea level anomalies.
