Weather forecasts lose reliability after ~10 days, but farmers, resource managers, and communities make critical decisions weeks in advance.
New in @Nature: a lightweight ML method that corrects predictable errors in physics-based and AI weather forecasts at extended lead times.

In @Nature this week, our new research shows how machine learning can improve weather forecasts two to six weeks out, a timeframe that's historically been very difficult to predict.

It's exciting to see the potential of this work to help us better prepare for extreme weather, manage natural resources, and make more informed decisions in agriculture.

There's a broader lesson here... the future may not just be about ever-more-capable models, but about building intelligent verification systems around them: systems that learn where models are systematically wrong, reason about cause and effect, and continuously calibrate predictions against reality.
