Google DeepMind’s latest AI weather forecasting model, GenCast, is revolutionizing how weather predictions are made. By outperforming the European Centre for Medium-Range Weather Forecasts’ (ECMWF) ENS system, GenCast delivers faster, more accurate forecasts up to 15 days in advance.
GenCast is a diffusion AI model adapted to Earth’s spherical geometry. It produces ensembles of 50+ forecasts, representing different potential scenarios. This method captures uncertainties and avoids overconfidence, making it ideal for extreme event predictions.
