Machine learning weather models: distinguishing initial-condition and model error

A new research paper explores the distinction between initial-condition errors and model errors in machine learning weather models. The study evaluates gated and ungated optimizations in GraphCast and Pangu-Weather, measuring performance against ERA5 data. Results indicate that while gating can lead to more comparable improvements between models, it doesn't always guarantee better performance, especially when optimization is stopped early. AI

IMPACT This research could lead to more accurate weather forecasting by better understanding and mitigating errors in ML models.
