The AI system outperformed existing, numerical forecasting methods nine times out of ten—though it started to stumble when asked to forecast beyond about 90 minutes. Other big firms with AI expertise are getting involved, too. A paper published in Nature on July 5th described Pangu-Weather, an AI system built by Huawei, a Chinese firm, and trained on 39 years of weather data. Huawei claims Pangu-Weather can produce week-ahead predictions comparable in accuracy to forecasts from outfits like ECMWF, but thousands of times faster. Last year Nvidia, an American chipmaker, claimed that FourCastNet, its AI weather program, could generate, in two seconds, a forecast that can predict hurricanes and heavy rain up to a week in advance. “}}
