Thirty seconds, and we'll have the prediction of global weather for the next 10 days.
This achievement comes from "FengWu," a global weather forecast model based on artificial intelligence (AI) released in April this year.

Medium-range weather forecasting
The name of the AI weather forecasting system "FengWu" was derived from the ancient Chinese anemometer used from the Han Dynasty which has been considered as the earliest prototype for measuring wind speed and orientation, according to Ouyang Wanli, leading scientist at Shanghai AI Laboratory, one of its developers.

The model, trained on 39 years of global data, can forecast global weather for a 7-day lead time with higher accuracy than the Integrated Forecast System, one of the best global numerical weather prediction system, while being more than 10,000 times faster at the same spatial resolution, according to a report published on the academic journal Nature.

Nowcasting of extreme precipitation
Nowcasting refers to very short-range weather forecast over a period up to 6 hours ahead, which provides detailed information about the weather in real time.
Nowcasting with "high resolution, long lead times and local details" is greatly needed to forecast extreme precipitation, a considerable contributor to meteorological disasters, and mitigate its socioeconomic effects, said a Nature report on July 5.
