WeatherNext 2

WeatherNext 2 is the latest model in the WeatherNext family — developed jointly by Google DeepMind and Google Research — for AI-based weather forecasting. The model generates fast, probabilistic (ensemble) forecasts of the atmospheric state, including wind speed and direction, precipitation and pressure.

Compared to the previous generation, WeatherNext 2 is about 8x faster (a forecast can be generated in under a minute on a single TPU accelerator) and predicts extreme events more accurately. The extra speed allows analyzing many more possible scenarios per forecast. The model produces forecasts in six-hour steps, four times a day; in the experimental Weather Lab it supports cyclone prediction up to 15 days in advance.

WeatherNext 2 is available through Google Cloud (Vertex AI / Gemini Enterprise Agent Platform), BigQuery, Google Earth Engine and the Google Maps Platform Weather API, and powers Google products: Search, Gemini and Pixel Weather. Note: the architecture details, exact spatial resolution and official release date are not stated on the accessible Google pages.
