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
