Google has introduced WeatherNext 3, an artificial intelligence weather forecasting system that diverges from conventional meteorological methods by combining machine learning with real-time satellite imagery and historical weather patterns. The model generates detailed hourly predictions with improved accuracy for precipitation forecasting, representing a significant upgrade over its predecessor and traditional supercomputer-based simulation approaches.

WeatherNext 3 will be integrated into Google's consumer products—Search, Maps, and the Gemini assistant—while also being made available to researchers through Google Cloud. The system has demonstrated its effectiveness by achieving the top ranking on Operational WeatherBench, an independent evaluation framework, where it surpassed competing deep-learning weather models from Microsoft and Nvidia.
