New study examines scale-aware scoring rules for AI weather forecasts

By PulseAugur Editorial · [1 sources] ·

A preliminary study explored the impact of different scoring rules on machine-learned probabilistic weather forecast models. Researchers compared variations of the AIFS-CRPS model trained with univariate and multivariate scoring rules, including the Continuous Ranked Probability Score (CRPS), a global energy score, and a graph energy score. While overall forecast skill was similar across standard metrics, the graph energy score showed improved performance in tropical regions, and all scale-aware setups enhanced forecast realism by adjusting scale weights.

    On the sensitivity of machine-learned probabilistic weather forecast models to scale-aware scoring rules

    arXiv:2607.19161v1 Announce Type: cross Abstract: Probabilistic forecast models can be machine-learned from data using loss functions based on scoring rules such as the Continuous Ranked Probability Score (CRPS). This note summarises a preliminary study comparing versions of AIFS…
