Google DeepMind Unveils WeatherNext 3, an Advanced AI Weather Forecasting Model

Key Intelligence

• ■Google DeepMind has launched WeatherNext 3, its most advanced and accurate global AI weather model to date.
• ■The new model offers hourly forecasts, significantly improving predictions for critical sectors like energy markets, where precise, short-term data is crucial for grid management and renewable energy integration.
• ■WeatherNext 3 surpasses traditional numerical weather prediction (NWP) systems, like the European Centre for Medium-Range Weather Forecasts (ECMWF) HRES, in accuracy for 90% of weather variables up to five days out.
• ■The AI model is substantially faster and more energy-efficient, generating a 10-day global forecast in just over a minute on a single GPU, a fraction of the time and resources required by traditional supercomputers.
• ■This improved forecasting capability has broad applications, from enhancing daily consumer weather predictions to optimizing industrial operations and disaster preparedness.
