Google Launches Enhanced AI Weather Model for More Accurate Forecasts
Google has introduced an updated artificial intelligence (AI) model called WeatherNext 3, which offers more accurate and detailed weather forecasts. The new system uses real-time satellite data to produce hourly global predictions with a resolution five times sharper than its previous version. This advancement allows for better forecasting of fast-moving systems like rain and snowfall. The improved spatial and temporal resolution—down to 5 kilometers compared to the prior model’s 25-kilometer grid—enables more precise temperature, moisture, and wind speed predictions at turbine height (100 meters). This is especially beneficial in regions with fewer ground-based weather instruments. Google claims precipitation forecasts are up to 50% more accurate for one-day-ahead outlooks. The model also supports renewable energy forecasting by predicting conditions relevant to solar and wind power generation, aligning with the company’s growing data center demands.
