AI Beats Supercomputers at Month-Long Weather Forecasts

A new artificial intelligence (AI) tool can predict weather up to a month in advance, outperforming the supercomputers currently used by national forecasting agencies. The system, developed by researchers at a leading university, uses machine learning—a type of AI that learns from data—to analyze historical weather patterns. It then generates forecasts faster and more accurately than traditional physics-based models. In tests, the AI tool produced reliable predictions of temperature and rainfall weeks ahead, a task that typically challenges conventional systems. Researchers say the technology could help farmers, energy companies, and emergency planners prepare for extreme conditions. The team plans to refine the tool before making it available to weather agencies.
