High-resolution realistic simulation (collaborating with Y. Uchiyama)
With the advance of computing technique, one can simulate a real ocean
using unprecedently high resolution. The example shown here
is a simultion of Huntington Beach of Southern California using 100m
horizontal resolution. It shows the clear frontal evolution with
submesoscale filaments. The grid can resolve the water break
and rivers, which gives rise to reexamine the nearshore oceanic
dynamics.
With wind, wave and tides turned on in the numerical model, one can
reproduce the real oceanic movement with the model. The fine grid
configuration is being applied to study the dispersion of the discharge from outfall and sedimental transport in the area.
Besides the computational challenge in terms of memory, storage and so
on, well-resolved submesoscale eddies evolution can help us to
reconsider
the parameterization of the subgrid turbulence.
