- Split-Explicit Eulerian Model:
- Pressure and temperature diagnosed from thermodynamics
- Two time level split-explicit time integration
- Flux-form prognostic equations in terms of conserved variables
- Accurate shape preserving advection
- Both terrain-following height and mass coordinates being tested
- Semi-Implicit Semi-Lagrangian Model:
- Unstaggered (A) grid
- Forward trajectories with cascade interpolation back to grid
- High order compact differencing
- Terrain following hybrid coordinate
