Decadal climate prediction lies at the intersection of an initial conditions problem and an
external forcing/boundary condition problem.
IPCC AR5 Chapter 11
Earth System Model (ESM) predictions use the same principles as numerical weather prediction:
initialize an ESM with a reanalysis or model solution, and then integrate it forward.

Editor's Notes

  • #3: Mention initialization vs. external forcing and how we need to get both right.
  • #4: Mention that this is hindcast prediction. Perfect model prediction initializes off a control run to keep the prediction study self-contained and purely theoretical. We also are dependent on external forcing. You see the increase in SST.
  • #7: Can nod to other existing packages
