Google DeepMind and Google Research have launched WeatherNext 3, an artificial intelligence model designed to enhance global weather forecasting precision. The system utilizes real-time satellite data and ground station observations to provide hourly updates at high resolutions, including a 5-kilometer scale for temperature and humidity. Research indicates the model offers significant improvements over traditional numerical forecasting methods. It can reduce precipitation error metrics by up to 50% and provides enhanced accuracy for predicting cyclones, hurricanes, and typhoons, potentially offering an extra day of warning. By delivering three-day forecasts with the accuracy previously seen in two-day predictions, the model aims to mitigate delays associated with traditional numerical weather prediction models. The technology is being integrated into various Google services, including Search, Maps, Gemini, ~~and~~ Google Earth ~~Engine.~~ Engine, the Maps Platform Weather API, and Google Cloud services. It also provides specialized data for the renewable energy sector, such as wind speeds at 100-meter turbine heights and solar irradiance ~~predictions.~~ predictions to assist grid operators.
