Reference Configuration for NEMO

Within the SURF source package, several input model parameters for NEMO are fixed and predefined in the file setParFix.ncl. The fixed parameters include:

  • Tracer Advection Scheme: The Monotonic Upstream Scheme for Conservation Laws (MUSCL) was used for tracer advection. This scheme provides high accuracy while maintaining monotonicity in the numerical solutions, preventing spurious oscillations.
  • Momentum Advection Scheme: The Energy and Enstrophy Conservative (EEN) scheme was applied for momentum advection. This method, as described by Arakawa and Lamb (1981) and Barnier et al. (2006), conserves both energy and enstrophy, ensuring a physically realistic representation of momentum transport.
  • Lateral Close Boundary Conditions: No-slip conditions were implemented on all closed lateral boundaries, ensuring that there is no unrealistic velocity at the boundaries of the computational domain.
  • Bottom Friction: The bottom friction was parameterized using a quadratic function, which accurately simulates frictional forces at the ocean floor.
