An AI tool improves weather forecasts up to a month ahead

An innovative artificial-intelligence application enhances weather forecasting in the difficult subseasonal range, providing accurate forecasts of precipitation, temperature and pressure 3–5 weeks in advance. The tool refines both physics- and AI-based weather models and improves the early prediction of extremes of heat, cold, rainfall and flooding. The tool boosts the ability of physics- and AI-based forecasting models to predict typical and extreme weather events.
