AI-assisted: summaries and questions may be incomplete or incorrect. Verify important details with the linked original reporting.
Summary
- Google DeepMind unveiled WeatherNext 2, an AI model that generates hundreds of possible weather scenarios in under a minute on a single chip, running 8x faster than its predecessor.
- It outperforms the previous WeatherNext model on 99.9% of variables and forecasts down to one-hour resolution.
- DeepMind's related GenCast beats the top operational system — ECMWF's ENS — for day-to-day and extreme weather up to 15 days out; NOAA is also deploying AI-driven global models.
The question
AI is rapidly overtaking traditional physics-based weather forecasting.
