Summary: Multi-satellite and buoy observation data were used to analyze the ocean response to Super Typhoon Nepartak offshore of Taiwan in 2016. The data revealed that a warm water layer and deep mixed layer provided favorable conditions for typhoon intensification. The response of the ocean differed between two buoys, with one experiencing cooling and the other showing a three-layer vertical structure. These results highlight the importance of considering the movement of ocean eddies in predicting changes in the ocean environment and typhoon intensity.

Summary: This study reveals the significant impact of interactions between typhoons and eddies on the upper ocean responses, particularly the enhanced sea surface cooling due to the presence of eddies. It also highlights the important roles of vertical mixing and advection of eddy-related currents in sea surface cooling.

Summary: This article examines the upper ocean response to Typhoon Nakri in the South China Sea in 2019. The study finds that the sudden turning of the typhoon's track plays a significant role in modulating the upper ocean response, especially in the presence of warm eddies. Typhoon Nakri led to the expansion of a cold eddy and weakened a warm eddy, as well as triggering a bloom of phytoplankton.

Summary: The interactions between mesoscale eddies and typhoons play a crucial role in influencing sea surface cooling (SSC) induced by typhoons. Different relative positions of typhoons and eddies can lead to variations in the cooling effects, with cyclonic and anticyclonic eddies having different impacts on the cooling patterns along typhoon tracks in the South China Sea. Overall, the influences of cyclonic eddies (CEs) and anticyclonic eddies (AEs) on typhoon-induced local SSC are relatively weak in the SCS.

Summary: This study reconstructed the details of coastal hypoxia development in the East China Sea in response to Typhoon Bavi using numerical modeling. The results showed that typhoon-induced oceanic advection played an important role in the development of hypoxia and redistribution of deposited organic matter in coastal shelf seas.

Summary: This study investigates the physical and biochemical properties, 3-dimensional structure, and evolution of a long-lasting cyclonic eddy (CE) in the Straits of Florida along the Loop Current/Florida Current front using satellite observations, Argo profiling float records, shipborne measurements, and simulations from HYCOM. The study reveals the formation and quasi-stationary behavior of the eddy, as well as its characteristics and mechanisms of growth and evolution.

Summary: Mesoscale eddies in the North Pacific Subtropical Gyre were found to enhance nutrient injection into the photic zone, affecting the magnitude and composition of particle export to depth. Biogenic silica fluxes were significantly higher at both the cores and edges of cyclonic eddies, with peak values occurring during the mature stage. During the bloom season, all elemental fluxes were reduced in cyclonic eddies compared to non-eddy references.

Summary: The study shows that the cyclonic mode of Arctic Ocean surface circulation is influenced by the Arctic Oscillation, with changes occurring with variations in the AO value. The complex cyclonic mode includes effects such as increased sea ice export, increased freshwater, and freshened Beaufort Sea.

Summary: A coupled ocean-wave-sea spray model system was utilized to investigate the impacts of sea spray and sea surface roughness on the upper ocean response to Super Typhoon Haitang. The study found that the effects of sea spray and sea surface roughness on the right side of the storm can compensate for the overestimation of sea surface cooling response, leading to enhanced cooling along the left edges of the cooling area.

Summary: The study highlights the importance of rainfall in freshwater input to the surface ocean and how different rain types and ocean stratification conditions can influence the timing and duration of the salinity response to rainfall. The results show that strong stratification inhibits freshwater mixing and allows near-surface salinity anomalies to persist following rain, while different rainfall types result in different mixing behaviors of salinity anomalies.

Summary: This study investigates the response of orographic precipitation in a typhoon environment to global warming using high-resolution simulations. The experiments show that under warming, a precipitation maximum may occur in the downstream region of a mountain or strengthen and shift upwind if it already exists in the current climate. This has critical implications for flooding risk management in mountainous regions.

Summary: The global ocean overturning circulation is crucial for climate evolution and is sensitive to the mesoscale eddy energy dissipation timescale. This study highlights the importance of constraining uncertainties associated with eddy energy dissipation for climate model projections over centennial timescales and paleoclimate simulations over millennial timescales.

Summary: This study presents and discusses a modeling case study based on observations from the Dynamics of the Madden-Julian Oscillation field campaign, aiming to investigate ocean-atmosphere coupling and boundary-layer structure over an oceanic diurnal warm layer. The research uses a 1D oceanic model with high vertical resolution to study the mechanisms responsible for the formation and decay of the diurnal warm layer, highlighting the competing impact of various factors. The atmospheric large-eddy simulation coupled with the 1D oceanic model is able to reproduce surface fluxes and boundary-layer structures, providing insights into parametrizations' ability to handle ocean-atmosphere coupling and its impact on the atmospheric boundary layer.

Summary: Studies have shown that mesoscale eddies in the Southern Ocean affect the distribution of micronekton, which are important prey for megafauna. This study analyzes acoustic observations in a cyclonic eddy and its surrounding waters, revealing that the acoustic backscatter distribution matches the underwater light conditions of the eddy core, periphery, and surrounding waters at scales smaller than 10 km. The results suggest that the eddy maintains its biological characteristics from its source waters, creating a unique habitat compared to its surroundings.

Summary: This study investigates the mechanisms of inner-core sea surface cooling (SSCIC) induced by tropical cyclones (TCs) using a linear two-layer theory and OGCM experiments. The results suggest that the pattern of inner-core mixing can be explained by wind-driven currents, with the intensity of SSCIC inversely proportional to TC moving speed. The study emphasizes the different roles of mixing, upwelling, and horizontal advection for fast- and slow-moving TCs in influencing SSCIC.
