Foil 49 Example: Atmosphere Model

From Master Foilset for CPS615 Introduction -- Material from Culler and Koelbel Computational Science for Simulations -- Fall Semester 1998. by Geoffrey C. Fox, Nancy McCracken
1 Simulate atmospheric processes
  • Conservation of momentum, mass, energy
  • Ideal gas law, hydrostatic approximation
2 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
3 Computation includes
  • Atmospheric dynamics: finite difference
  • "Physics" (radiation etc.) in vertical only
