“Improved weather prediction using artificial intelligence promises to take a big step forward with the launch of a new European system, which can outperform conventional forecasting methods for up to 15 days ahead.

While tech companies and meteorological offices around the world are already applying AI to the weather, the European Centre for Medium-range Weather Forecasts (ECMWF) said its operational model broke new ground by making global predictions freely available to everyone at any time…

An experimental version tested over the past 18 months showed the system was about 20 per cent more accurate on key predictions than the best conventional methods, which feed millions of worldwide weather observations into supercomputers and crunch them with physics-based equations.

The new European system could predict the track of a tropical cyclone 12 hours further ahead, giving valuable extra warning time for severe events.”
