Enterprise AI Analysis
Global performance benchmarking of artificial intelligence models in atmospheric river forecasting
This analysis benchmarks five state-of-the-art AI models (Pangu, FCN2, FuXi, GraphCast, NeuralGCM) and one numerical model (FGOALS) for atmospheric river (AR) forecasting. It assesses their performance across global and regional scales, focusing on meteorological fields and AR-specific metrics. Key findings show FuXi excelling globally for general meteorological fields at 10-day lead times. However, for AR intensity, the hybrid NeuralGCM model, which incorporates numerical components, shows superior regional performance. Despite these advancements, accurately predicting AR landfall locations beyond one week remains a significant challenge, highlighting the need for further model refinement for region-specific forecasts.

Case Study: North American AR Landfall (Dec 2023)
A powerful AR event impacted the northern Pacific coast of North America in December 2023, causing widespread flooding. Purely statistical models struggled to reproduce the cyclone's structure and wind direction by 5 days out. In contrast, NeuralGCM demonstrated relatively better performance, more closely matching the observed location and structure of the AR at 10-day lead times. However, Pangu, FCN2, and FuXi predicted a narrower, displaced landfall, and GraphCast failed to forecast it entirely.
