Google has unveiled GenCast, a cutting-edge AI-driven weather forecasting model, in a paper published in Nature. The model employs a diffusion-based approach, tailored for Earth’s geometry, to offer highly accurate weather predictions. GenCast has been trained on over 40 years of historical data from ECMWF archives, which enables it to outperform traditional systems, such as ECMWF’s ENS, particularly for longer-range
