China Announces Weather Forecasting System with 5km Resolution

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.

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.
