Summary: A modified analytical solution was developed to simulate the flow pattern of the Kuroshio intrusion northeast of Taiwan, maintaining horizontal momentum balance. The new model accurately predicts the direction of the Kuroshio intrusion and aligns well with observational data, offering potential applications in regions with different flow patterns.

Summary: This study investigated the long-term variability of Kuroshio shelf intrusion (KSI) northeast of Taiwan and its relationship with current and temperature variability in the East China Sea (ECS). The results showed that the KSI had significant changes in the 2000s, while it was relatively stable in the 1990s and 2010s, accompanied by a westward shift of the Kuroshio axis and warming.

Summary: This research addresses the practical requirements in the sustainable deployment of ocean moored buoy observing networks. A multi-objective mathematical model is developed for allocating ocean buoy stations based on Tobler's first law of geography. A heuristic method based on a multiple-objective particles swarm optimization algorithm is developed to calculate the model. The efficiency of the proposed model and algorithms in solving station location problems is verified through a series of experiments.

Summary: The intrusion of the Kuroshio has an impact on the abundance and composition of microplastics in the South China Sea, but it is not the dominant influencing factor. The effects of the Kuroshio intrusion appear to be a combination of dilution and biogeochemical influences. Further research is needed to understand the comprehensive impact of Kuroshio intrusion on microplastics fate in the Western Boundary Current system.

Summary: This research conducts a dynamic simulation analysis of a CALM moored tanker system and establishes a double spring hydrodynamic response system model. Numerical analysis shows that a pullback force of 800 kN effectively reduces motion and maintains a safe distance between the tanker and the buoy, preventing fishtailing and buoy kissing. Therefore, it is recommended to have a tug present while mooring a tanker to the CALM system.

Summary: The study shows that the Kuroshio intrusion through the Luzon Strait affects precipitation in southwestern Taiwan, bringing in significant freshwater influx with each event. By analyzing moisture budget, it is found that the main source of the precipitation anomaly is vertical advection of moisture.

Summary: This study investigates the mechanism of the abrupt decay of the Zhejiang-Fujian coastal front (ZFCF) during early spring using satellite observation and numerical simulation. The results show that wind, heat flux, and the Zhejiang-Fujian coastal current (ZFCC) have significant relationships with the variation of ZFCF. Net heat flux and horizontal advection are important in determining the temperature difference between two water masses of ZFCF. Numerical simulations successfully reproduce the observed abrupt change process of ZFCF. The weakening of ZFCC and the heating effect of the Kuroshio Intrusion (KI) water contribute to the abrupt decay of ZFCF.

Summary: The study showed that Kuroshio intrusion has a significant impact on the ciliate community in the northern South China Sea, with environmental factors playing a marginal role. Taxonomically diverse ciliates, mainly belonging to classes Spirotrichea and Phyllopharyngea, were sensitive to Kuroshio Current intrusion. The ciliate community exhibited differential niches in response to the Kuroshio intrusion scenarios, highlighting winner and loser species.

Summary: This study investigated the distribution of PAHs in different water bodies of the South China Sea and found that the decrease in PAH concentrations in the northern SCS was related to the intrusion of the Kuroshio Current.

Summary: The intensity of Zhejiang coastal upwelling (ZCU) is the principal factor influencing the coastal primary productivity of the East China Sea (ECS) in summer, while the Kuroshio intrusion (KI) has a relatively smaller impact. Strong ZCU leads to higher nutrient concentrations and greater nutrient supplies in nearshore areas. The years 2013 and 2018 were identified as strong and weak ZCU years, respectively, with significant differences in nutrient concentrations and phytoplankton biomass.

Summary: In this study, the 4D-Var data assimilation technique is applied to the East China Sea using the ROMS model, allowing for optimization of initial conditions, boundary conditions, and surface forcing. The impact of tidal forcing on the simulation results is evaluated, as well as the contributions of different types of observations. The study highlights the importance of accurately capturing tidal processes in the modeling of the East China Sea.

Summary: This study investigates the source-to-sink processes of terrigenous sediment in the northeastern South China Sea. The results show that sediment is primarily derived from Taiwan, and sea level changes play a significant role in sedimentation. The intrusion of the Kuroshio current and weakening of the East Asian monsoon also affect sedimentation.

Summary: The study found that high salinity often occurs at the subsurface salinity maximum in the northern South China Sea, especially near the Luzon Strait in winter, while it tends to be located in deeper waters in summer. This suggests that outer sea water gradually mixes with South China Sea water after passing through the Luzon Strait. Factors such as the strength of the Kuroshio intrusion, local wind stress curl, and anticyclonic eddies play important roles in the appearance and distribution of anomalously high salinity in the subsurface salinity maximum in this region.

Summary: This study investigated two processes of high-salinity water intrusion in the northeastern South China Sea during fall-winter of 2015/2016 using data from Argo float, satellite altimetry, and reanalysis. The results showed that eddy pairs and the interior circulation of the South China Sea jointly affected the transport of high-salinity water.

Summary: This study employed a spatiotemporal deep-learning method to correct biases in numerical ocean wave forecasts. By using a correction model driven by both wave and wind fields and a novel pixel-switch loss function, the corrected results performed well in different seasons and improved the accuracy of the original forecasts.
