Abstract
We present a costal, high-resolution, one-way-nested
thermo-hydrodynamical model of the NW Mediterranean, based on the code
SYMPHONIE (Marsaleix et al, 2008).
The model provides the three velocity components, the free surface
elevation, and the temperature and salinity fields.
It solves the Reynolds-averaged Navier-Stokes equations, using the
hydrostatic and Boussinesq approximation, and the equations of the mass
and tracers' conservation. The turbulence closure is achieved through a
prognostic equation for the turbulent kinetic energy and a diagnostic
equation for the mixing and dissipation length scales.
A generalized vertical coordinate and a staggered horizontal grid are
used. Computation costs are limited thanks to a time splitting
technique
that allow to compute the vertical shear of velocity and the three
depth-averaged components separately with appropriate time steps.
Radiation conditions combined to restoring terms to the large-scale
circulation (Mediterranean Forecasting System data) are applied at the
open boundaries, and bulk formulas are used for the meteorological
forcing (Météo-France data).
A ten-year simulation (2001-2009) is available at COM. The model data
are proposed for a comparison with the ANTARES observations in order to
both validate the model, in particular in the deep layers, and to use
its information for future observations planning.
