Foil 87 Example: Atmosphere Model

From CPS615-Introduction-Course,Driving Technology and HPCC Current Status and Futures CPS615 Basic Simulation Track for Computational Science -- Fall Semester 98. by Geoffrey C. Fox, (Some Culler, Koelbel material)
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
