China said it can now predict weather 10 days in advance at a cutting-edge resolution of 5km (3.1 miles), finer than most major systems in routine use around the world.
The advance was achieved by a Chinese-developed weather forecasting model running on Sugon 8,000, a massive home-grown computing system built entirely with domestically made AI chips .
Most major global forecasting systems have resolutions of roughly 5km to 10km, according to the China Meteorological Administration and Beijing-based computing company Sugon, which jointly announced the results on Tuesday.
For instance, the Global Forecast System – the main global weather model run by the US National Weather Service – has a maximum resolution of about 13km.
