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: Based on satellite observations, the authors demonstrate that the average rain rate of tropical cyclones (TCs) significantly increases with their translation speed. On average, the rain rate of a fast-moving TC is about 24% higher than that of a slow-moving one. These findings provide important insights into understanding the changes in rain rate for translating TCs and have implications for short-term TC rainfall forecasts and disaster preparedness.

Summary: The study shows that TC surge in Shanghai is highly sensitive to both landfall location and intensity. However, the potential surge hazard due to poleward migration of TCs is estimated to be approximately three times larger than that caused by intensity change, making the long-term surge risk in Shanghai more sensitive to changes in TC track and landfall location rather than intensity. This sensitivity may also apply elsewhere and in the future.

Summary: This study analyzes the rainfall evolution of two landfalling tropical cyclones, SOULIK and MARIA, in Fujian province. The results show differences in rainfall intensity and distribution between the two cyclones, and provide insights into the underlying dynamic factors influencing their rainfall patterns.

Summary: The vertical wind structure of translating tropical cyclones, including asymmetric inflow angles, has been studied through dropsonde data primarily from strong cyclones in the Atlantic. This study focuses on weak landfalling cyclones near Hong Kong and finds that decaying tropical storms exhibit larger mid- to low-level inflow angles compared to intensifying or steady-state storms. The inflow angles converge near the top of the boundary layer for intensifying, steady-state, and decaying tropical storms. Decreasing wind speed across the boundary layer is observed in all three cases. The stronger inflow in decaying storms is attributed to enhanced surface friction over land during weakening stages.

Summary: This study aims to describe the cycle of tropical cyclone (TC) precipitation magnitude through analyzing satellite information, with a focus on the overland events. It found that TCs usually experience rainfall maxima in regions adjacent to the coast when more than 50% of their rainfall area is over the water. The research also shows the relationship between rainfall intensity, volumetric rain, and rainfall area, which increases with wind speed intensity when the total extent is considered.

Summary: Landfalling tropical cyclones in India cause severe damage and economic losses. The distribution of extreme rainfall and severity of flooding from these cyclones depend on factors such as translation speed, track length, size, and antecedent soil moisture conditions. Monitoring land-surface characteristics and cyclone track predictions are crucial for assessing the potential of flooding.

Summary: This study investigated the temporal rainfall patterns in a tropical city to facilitate rainfall design by analyzing 5-min rainfall data from three raingauge stations. The analysis employed a storm-event-based approach using the concept of inter-event time definition and rainfall depth/duration/intensity thresholds, aiming to improve the representativeness of design rainfall and facilitate rainfall-runoff modeling for urban flood control in a tropical region.

Summary: This study evaluates the performance of different versions of the DSAEF_LTP model in simulating heavy rainfall associated with landfalling tropical cyclones in China. The results show that the improved version, V1.1, has significantly better performance compared to V1.0. Furthermore, the introduction of the V1.1R subregional re-ensemble scheme further improves the forecast performance.

Summary: This study used the IBTrACS dataset to assess surface wind fields near a tropical cyclone (TC) center. SAR data accurately described TC intensity and size under severe conditions. A new statistical wind structure model was developed using ERA5 data alone. The warm sea surface produced stronger TC wind fields and heavier precipitation, with a correlation between wind speed and precipitation that increased as sea surface temperature decreased.

Summary: This single-center cohort study found that IP-10 levels correlated with COVID-19 severity and admission to the intensive care unit, and corticosteroid therapy significantly decreased IP-10 levels. Serial IP-10 measurements may serve as an actionable aid in managing inflammation and guiding therapeutic decisions in COVID-19 patients.

Summary: The study found that the inner-core rainfall strength of Atlantic tropical cyclones is mainly influenced by the inherent primary circulation of the cyclones and less affected by large-scale environmental conditions, while the total rainfall area is primarily influenced by large-scale low and high pressure systems, partially influenced by environmental flows, sea surface temperature, humidity, and maximum wind speed.

Summary: The study indicates that aging dams in the United States are at an increased risk of breach due to intensified rainfall, with Hurricane rainfall having a more severe impact on downstream hydraulic facilities. Future extreme weather events may further exacerbate this situation.

Summary: From 10 July to 12 July 2021, a long-lasting southwest vortex moved across China and resulted in heavy rainfall events. This unique vortex exhibited an unusually long lifespan compared to typical southwest vortices, which are usually quasi-stationary. The formation and persistence of this vortex were influenced by favorable environmental conditions characterized by upper-level divergence, middle-tropospheric warm advection, and a strong low-level jet. The vortex interacted significantly with a middle-tropospheric mesoscale vortex and was steered northeastward by the southwesterly wind associated with a deep shortwave trough.

Summary: Online data assimilation performs better than offline data assimilation when the predictability of the system exceeds the averaging time of observations. The ocean plays a crucial role in extending predictability, aiding online data assimilation to outperform offline data assimilation. Moreover, the observations of near-surface air temperature over land are highly valuable in updating ocean variables, highlighting the importance of utilizing cross-domain covariance information between the atmosphere and the ocean in paleoclimate reconstruction.
