何が起こったのか
Google DeepMind and Google Research announced WeatherNext 3 on September 3. Google says the AI forecasting system uses live satellite observations and produces a new forecast each hour.
Google reports five-kilometer resolution for and moisture, ten kilometers for other surface variables, and twenty-five kilometers for atmospheric variables. It says forecasts are integrated into Search, Gemini, Maps and its cloud offerings.
More frequent updates and finer spatial detail could help users follow rapidly changing local conditions. These are Google's reported capabilities; AI Understanding has not independently tested the model.
Google also describes forecasts for wind at turbine height and solar-energy variables. Their practical value depends on accuracy in the location and time period that a user needs.

Core takeaway: Fine-tuning teaches models how to speak (form, style, syntax); RAG teaches models what to say (verifiable facts). Never use fine-tuning alone for factual memory.

Independent evaluations and performance during unusual weather will matter when assessing reliability. A global performance claim does not establish accuracy for every location or event.
