WeatherNext 3: Making Global Weather Predictions with 5 km Accuracy

The world is following biology and chemistry. In meteorology, AI will drive accuracy. Google has just added WeatherNext 3 to Google Search, Maps, and Gemini. It will be the default way hundreds of millions of users get their forecast.

WeatherNext 3 is a new AI weather model developed by DeepMind. Compared to the previous version, WeatherNext 3 boasts a resolution of 5 km, instead of 25 km, improves precipitation prediction accuracy by 60%, provides hourly predictions (instead of every six hours), and is the first one to be deployed in real-time on satellite data. Independently evaluated by Operational WeatherBench, WeatherNext 3 performed better than competing models developed by Microsoft, Nvidia, European Centre for Medium-Range Weather Forecasts, and the National Weather Service of the United States.
