AdaWeather: Adaptively Mixing Probabilistic Weather Forecasts with Logarithmic Regret

arXiv:2606.02663v1 Announce Type: new Abstract: Recent advances in machine learning have produced probabilistic weather forecasting models comparable to state-of-the-art numerical weather predictors. But no model consistently dominates spatio-temporally, and relative performance is highly context-dependent. This motivates adaptive methods for combining multiple forecasts to obtain improvements and robustness. While combined forecasts have been proposed in the literature, these are achieved either through supervised learning or through prediction with expert advice methods. We introduce AdaWeat

Why this matters
Why now

Advances in machine learning are enabling more sophisticated probabilistic weather forecasting, creating a competitive landscape where no single model consistently outperforms others.

Why it’s important

Improved weather forecasting directly impacts sectors from agriculture to logistics, while also highlighting the practical application and competitive dynamics of advanced AI models.

What changes

The development of adaptive methods for combining forecasts will likely lead to more accurate and robust weather predictions, reducing reliance on individual model performance.
