A new AI weather forecasting model developed by researchers demonstrates significant improvements in both speed and accuracy compared to traditional physics-based systems. The model, trained on decades of historical weather data, can generate high-resolution global forecasts in minutes rather than hours. Initial tests show it matches or exceeds the performance of established numerical weather prediction models for key variables like temperature and precipitation up to five days ahead. The system’s efficiency could enable more frequent updates and ensemble forecasting to better predict extreme weather events.
