=== Conversion ===
 
 
 
grib-netcdf-hdf5
 
 
 
=== Interpolation ====
 
 
 
z-level to MOHID geo
 
 
 
bilinear vs triangulation
 
 
 
linear horizontally and vertically
 
 
 
=== Boundary conditions ===
 
 
 
 
 
====Open boundary ====
 
 
 
high frequency vs low frequency = mohid 2D + 3D external solution
 
 
 
radiation + flow relaxation scheme
 
 
 
====Surface====
 
impose wind stress, solar radiation
 
 
 
Compute sensible heat, latent heat based in the water/air temperature, wind, relative humidity
 
 
 
 
 
=== Spin up ====
 
 
 
slow connection of terms: wind, tide, atmospheric pressure, baroclinc force
 
 
 
initial condition : salinity and temperature from external solutions, null sea level gradient and null velocities
 
 
 
initial strong relaxation of temperature and salinity in all domain
