Global Evaluation of AI and NWP Precipitation Forecasts During Atmospheric River Events

Excerpt

arXiv:2610.03758v1 Announce Type: cross Abstract: Atmospheric rivers (ARs) produce many of the world's most extreme precipitation events and hydrometeorological hazards. Although artificial intelligence weather prediction (AIWP) models have demonstrated skill comparable to or exceeding numerical weather prediction (NWP) systems for large-scale atmospheric variables, their ability to forecast AR-related precipitation remains insufficiently characterized globally. Here, we evaluate 24-hour precipi
