Artificial intelligence and the weather

A new machine-learning weather prediction model called GenCast can outperform the best traditional forecasting systems in at least some situations, according to a paper by Google DeepMind researchers published recently in Nature.

Using a diffusion model approach similar to artificial intelligence (AI) image generators, the system generates multiple forecasts to capture the complex behavior of the atmosphere. It does so with a fraction of the time and computing resources required for traditional approaches. – Full report
