Summary: Decade-long satellite observations show that different intensities and moving speeds of tropical cyclones result in varying sea surface salinity changes on their left and right sides, with the most intense storms causing salinification and being influenced by the vertical salinity gradient in the upper ocean and barrier layers.

Summary: This study highlights the significant influences of tropical transbasin variability (TBV) and ENSO on tropical cyclones in the western North Pacific, eastern North Pacific, and North Atlantic Ocean basins. The modulation of TC counts varies in each basin due to different effects of TBV and ENSO, with low-level relative vorticity and large-scale factors playing important roles in regulating TC frequency.

Summary: Using X-ray tomography, this study examines the sedimentary fabric of the Scrub Island lagoon in Anguilla, Caribbean, to understand the processes occurring during tropical cyclones and tsunamis. The fabric of tsunami deposits is highly homogenous, with variations associated with sediment concentration and flow strength. In contrast, the fabric of hurricane deposits shows more variability, potentially indicating successive waves.

Summary: Sediment-laden flows called turbidity currents play an important role in the transfer of sediment, nutrients, organic carbon, and pollutants from continental shelves to the deep sea via submarine canyons. However, the rise in sea level since the last glacial period has disconnected the majority of submarine canyons from their sediment inputs. This study presents detailed measurements of turbidity currents in a land-detached submarine canyon, showing similar frequency and speed to those in large land-attached canyons. The findings suggest that contemporary deep-sea particulate transport via land-detached canyons may have been underestimated.

Summary: Nonlinear wave-wave interactions play a critical role in the evolution of wave spectra in tropical cyclones, transferring energy from wind-sea to remotely generated waves. The peak waves act in a parasitic manner, taking energy from wind-sea to sustain their growth. This study provides strong validation of the importance of nonlinear processes in wind-wave evolution.

Summary: This study quantifies the contributions of tropical sea surface temperature (SST) variations during the boreal warm season to the interannual-to-decadal variability in tropical cyclone genesis frequency (TCGF) over the Northern Hemisphere ocean basins. The study finds that the dominant SST modes affecting TCGF vary among different basins and are related to ENSO, GW, PMM, AMO, PDO, and AMM. These modes explain a portion of the variance in TCGF in the North Atlantic, northeast Pacific, and northwest Pacific Oceans.

Summary: The frequency characteristics of northward-moving tropical cyclones (NTCs) in the western North Pacific (WNP) are analyzed, and the possible combined effect of El Niño-Southern Oscillation (ENSO) and the North Atlantic tripole (NAT) sea surface temperature anomaly (SSTA) is investigated. The results show that the NTC frequency in summer exhibits interannual and decadal variations. The NAT modulates the relationship between ENSO and NTCs. During positive NAT phases, the effect of ENSO on NTCs is clear, while during negative NAT phases, only El Niño has an effect on the NTC frequency.

Summary: The intensity of tropical cyclones is influenced by air-sea fluxes of enthalpy and momentum, with sea spray playing a crucial role in mediating these fluxes at high wind speeds. Parameterizing the influence of sea spray is essential in air-sea interaction schemes, but there is currently no consensus on the best parameterization for representing air-sea exchange in tropical cyclones, leading to substantially different intensity predictions. This paper reviews developments in parameterizations of sea spray-mediated fluxes and synthesizes common key findings across many studies.

Summary: This study confirms a sudden shift in the trend of tropical cyclone landfalls in southern and southeastern China at the end of the twentieth century. The decrease in southern China is attributed to a decrease in westward events, while the increase in southeastern China is linked to an increase in northwest events during peak season. These variations are mainly caused by changes in relative vorticity and vertical wind shear.

Summary: This study proposes a model using random forest method to predict the spatial and temporal evolution of sea surface temperature cooling induced by tropical cyclones. The model achieves good prediction performance by using 12 predictors related to tropical cyclone characteristics and pre-storm ocean conditions.

Summary: The study identifies an antiphase decadal variation in tropical cyclone (TC) genesis between the western North Pacific (WNP) and North Atlantic (NA) basins. This transbasin connection is triggered by the Atlantic multidecadal oscillation (AMO) and involves a subtropical east-west relay teleconnection. During a negative AMO phase, TC genesis is suppressed in the North Atlantic but enhanced in the western North Pacific due to changes in atmospheric and oceanic circulation patterns.

Summary: Tropical cyclones generate large and wide cold wakes along their trajectories, impacting the evolution of the cyclones themselves and reducing cloud coverage and rainfall. This study sheds light on the mechanisms of air-sea feedbacks triggered by cold wakes, which may vary at different latitudes. Further research is needed to assess the significant impact of cyclone-induced cloud cover anomalies on Earth's radiative budget.

Summary: This study reviews the mechanisms of large-volume stratigraphic traps in deepwater petroleum systems, focusing on the detachment of sands due to syndepositional or post-depositional erosive processes. These mechanisms can be classified based on timing of formation and process involved, and insights from modern seafloor systems are crucial in understanding the formation of detached sandbodies.

Summary: This study shows that the decline in Tibetan Plateau snow depth since 2000 has influenced the relationship between intensifying tropical cyclones over the western North Pacific and tropical Indian Ocean sea surface temperatures. The snow depth affects convective activity and leads to cooling of the tropical Indian Ocean in spring. The changes in the Indian Ocean SSTs weaken the connection between rapidly intensifying tropical cyclone frequency and spring tropical Indian Ocean SSTs.

Summary: The study found that the wave-dependent momentum flux has significant impacts on characteristics of tropical cyclones at different stages, including drag coefficient and track differences. The TC tracks of the wave-coupled AGCM tend to pass in a relatively eastward direction.
