AI Hurricane Predictions Are Storming the World of Weather Forecasting

A wall of high pressure stood in its westward path, poised to deflect the storm away from Florida and in a grand arc northeast. It was 10 days out from the earliest possible landfall--eons in weather forecasting--but meteorologists at the European Centre for Medium-Range Weather Forecasts, or ECMWF, were watching closely. The tiniest uncertainties could make the difference between a rainy day in Scotland or serious trouble for the US Northeast. Typically, weather forecasters would rely on models of atmospheric physics to make that call. This time, they had another tool: a new generation of AI-based weather models developed by chipmaker Nvidia, Chinese tech giant Huawei, and Google's AI unit DeepMind.
