Google DeepMind's WeatherNext AI adds a day's lead time to cyclone forecasts

Google DeepMind researchers say their WeatherNext AI models can forecast tropical cyclones with roughly an extra day of useful lead time, turning work that once needed building-sized supercomputers into 15-day runs that finish on a Tensor Processing Unit (TPU). In a Nature paper and a Google DeepMind technical account, Google DeepMind and Google Research report that three-day forecasts of a storm's track, intensity, and wind structure match the accuracy that leading operational models previously reached only two days out, an improvement they liken to about a decade of conventional meteorological progress.
