Google's latest AI weather model gives you no excuse to forget your umbrella

Summary

Google DeepMind and Google Research launched WeatherNext 3, an AI weather forecasting model delivering hourly predictions at 5km resolution. The system outperforms major traditional supercomputing forecasts on standard benchmarks and will power search, Maps, and Gemini.

Key Takeaways

1. WeatherNext 3 is the latest wave of a sea change in meteorology brought out by deep learning techniques, and Google says it will start feeding into weather information users see in search, Google Maps, and Gemini, as well as being available to users and researchers on Google’s cloud platforms.
2. As well as beating out other deep-learning models built by Google, Microsoft, Nvidia, and the European Center for Medium-Range Weather Forecasting, it also beats traditional forecasts from the US National Weather service and the ECMWF.
3. On key variables, researchers told TechCrunch, it can predict down to a resolution of 5km. Its evaluations on rain are 60% improved over WeatherNext 2, and it can now produce hourly forecasts, instead of the standard prediction every six hours.
