Model Coupling

The UCLA AGCM is a complex code representing many physical processes. Despite the complexity of the code, one can identify the following two major components:

  • AGCM/Dynamics, which computes the evolution of the fluid flow governed by the appropriate equations (the primative equations written in finite differences).
  • AGCM/Physics, which computs the effect of processes not resolved by the model's grid (such as convection on cloud scales) on processes that are resolved by the grid (such as the flow on the large scale)
