- 37. Fascinating rate of increase of FourCastNet’s weather prediction skill. Individual researchers yielding impressive skill gains from ablations independent of large architecture searches Skill gap reduced by more than half w.r.t IFS gold standard Skill gap reduced by more than half w.r.t IFS gold standard Acronym Alert: ACC: Anomaly Correlation Coefficient (metric of weather skill) IFS: The Integrated Forecast System, a gold standard weather model FCN: FourCastNet, our digital twin of weather. Ablations that seem to matter: • State vector size – adding upper atmosphere helped. • Only to a limit; adding other things has not immediately helped. • Model size: # of transformer blocks & hidden dimension. • Caveat: trades off with inference speed, training cost & memory use. • Open question: Most efficient route to improving DDWP accuracy.
