Today’s weather forecasts come from some of the most powerful computers on Earth. The huge machines churn through millions of calculations to solve equations to predict temperature, wind, rainfall, and other weather events. A forecast’s combined need for speed and accuracy taxes even the most modern computers.
The newly developed global weather model bases its predictions on the past 40 years of weather data, rather than on detailed physics calculations.
The simple, data-based AI model can simulate a year’s weather around the globe much more quickly and almost as well as traditional weather models, by taking similar repeated steps from one forecast to the next, according to a paper in the
Artificial intelligence can analyze past weather patterns to predict future events, much more efficiently and potentially someday more accurately than today’s technology, researchers say.
