Effects of wave-current interaction on water exchange in the Bohai Sea
The Bohai Sea is a typical continental shelf region, and its water exchange capacity has long been the focus of research. Wave-current interaction (WCI), as an important physical process for the continental shelf hydrodynamics, is worthy of further investigation due to its impact on water exchange in the Bohai Sea. In this study, based on the FVCOM-UnSWAN wave-current coupling model, the water exchange characteristics of the Bohai Sea under the influence of WCI were discussed using the conservative material tracer method. The effects of WCI on water exchange and hydrodynamics were further analyzed under both seasonal variations and extreme weather events. As the only channel connecting the Yellow Sea and the Bohai Sea, changes in the water exchange capacity of the Bohai Strait can reflect the change of the Bohai Sea. Focusing on this region, our results show that WCI modulates water exchange rates: enhancing exchange by approximately 1.3 % in winter, while exhibiting complex behavior in summer, initially suppressing and subsequently enhancing water exchange. During storm surge events, WCI plays a crucial role in modifying hydrodynamic conditions, increasing water elevation by 20 %–35 %, with changes in water velocity up to an order of magnitude larger compared to seasonal scales. During the water exchange process, WCI modifies the current velocity structure by introducing a non-conservative force Fw, among which the white-capping dissipation term plays a dominant role.
期刊介绍:
Continental Shelf Research publishes articles dealing with the biological, chemical, geological and physical oceanography of the shallow marine environment, from coastal and estuarine waters out to the shelf break. The continental shelf is a critical environment within the land-ocean continuum, and many processes, functions and problems in the continental shelf are driven by terrestrial inputs transported through the rivers and estuaries to the coastal and continental shelf areas. Manuscripts that deal with these topics must make a clear link to the continental shelf. Examples of research areas include:
Physical sedimentology and geomorphology
Geochemistry of the coastal ocean (inorganic and organic)
Marine environment and anthropogenic effects
Interaction of physical dynamics with natural and manmade shoreline features
Benthic, phytoplankton and zooplankton ecology
Coastal water and sediment quality, and ecosystem health
Benthic-pelagic coupling (physical and biogeochemical)
Interactions between physical dynamics (waves, currents, mixing, etc.) and biogeochemical cycles
Estuarine, coastal and shelf sea modelling and process studies.
