Nonlinear dynamics of Kuroshio intrusion in the Luzon Strait

This study used a 1.5-layer reduced-gravity numerical model to investigate the nonlinear dynamics of Kuroshio intrusion into the Luzon Strait.The model results suggested that both basin-scale wind curl and lateral friction are the primary factors that control the transformation of the flow,although inertia also plays an important role.Using an idealized model,both   (本文共9页) 阅读全文>>

Features and evaluation of sea/saltwater intrusion in southern Laizhou Bay

Understanding the degree of sea/saltwater intrusion in coastal regions is of great significance to treating the intrusion and improving the environment. Based on the character analysis of the sea/saltwater intrusion, five factors were selected in the fuzzy-synthetical evaluation approach to form the index system, so as to evaluate the...  (本文共8页) 阅读全文>>

Kuroshio intrusion in the Luzon Strait in an eddy-resolving ocean model and air-sea coupled model

The Kuroshio intrusion in a quasi-global eddy-resolving model (LICOMH) and a fully air-sea coupled mode(LICOMHC) was evaluated against observations.We found that the Kuroshio intrusion was exaggerated in the former,while biases were significantly attenuated in the latter.Luzon Strait transport (LST) in winter was reduced from–8.8×10~6 m~3/s in LICOMH to–6.0×10~6 m~3/s in LICOMHC.Further analysis showed that different...  (本文共17页) 阅读全文>>

State of seawater intrusion and its adaptive management countermeasures in Longkou City of China

Longkou City is a coastal area,and lacks water resources.The overexploitation of groundwater causes seawater intrusion.At present,seawater intrudes an area of 68 km~2.With the decrease of groundwater extraction,the seawater intrusion area has generally declined.The paper expounds the development process of seawater intrusion as well as the corresponding prevention and control measures of using groundwater replenishme...  (本文共13页) 阅读全文>>
