AI is outperforming our best weather forecasting tech, thanks to DeepMind

Data from a multi-decade simulation, called ERA5, is fed into the GraphCast graph network as a set of measurements at a particular point. By traversing the graph, GraphCasts predicts the next measurement for that point and for its neighbors.

Climatologists have spent decades amassing data on how the weather has changed at points around the globe. Efforts such as ERA5, a record of climate back to 1950, developed by the European Centre for Medium-Range Weather Forecasts (ECMWF), are a kind of simulation of the earth over time, a record of the wind speed, temperature, air pressure, and other variables, hour by hour.
