摘要

Abstract

We applied a primitive equation ocean model to simulate submesoscale activities and processes over the shelf of the northern South China Sea (NSCS) with a one-way nesting technology for downscaling. The temperature and density fields showed that submesoscale activities were ubiquitous in the NSCS shelf. The vertical velocity was considerably enhanced in submesoscale processes and could reach an average of 58 m per day in the subsurface. At this point

the mixed layer depth also was deepened along the front

and the surface kinetic energy also increased with the intense vertical movement induced by submesoscale activity. Thus

submesoscale stirring/mixing is important for tracers

such as temperature

salinity

nutrients

dissolved organic

and inorganic carbon. This result may have implication for climate and biogeochemical investigations.
