  • Parametrizations
  • Spatial (horizontal and vertical) and temporal resolution
  • Initialization
  • Dynamical core
  • Handling of some complex non-linear physical processes (i.e. snow)
  • Topography representation
  • How the mathematical equations are numerically implemented
  • The computer used
  • etc...

These are some of the main differences between 2 given numerical weather model.

With that being said, the same model will give different results when run on a different computer (Hong et al. 2013).
