Example: Atmosphere Model
Simulate atmospheric processes
- Conservation of momentum, mass, energy
- Ideal gas law, hydrostatic approximation
Represent atmosphere state by 3-D grid
- Periodic in two horizontal dimensions
- Nx.Ny.Nz: e.g., Ny=50-500, Nx=2Ny, Nz=15-30
Computation includes
- Atmospheric dynamics: finite difference
- “Physics” (radiation etc.) in vertical only
