Interpreting Data-Driven Weather Models

This paper addresses the crucial issue of interpretability in complex, data-driven weather models like GraphCast. It moves beyond simply assessing accuracy and delves into understanding *how* these models achieve their results. By applying techniques from Large Language Model interpretability, the authors aim to uncover the physical features encoded within the model's internal representations. This is a significant step towards building trust in these models and leveraging them for scientific discovery, as it allows researchers to understand the model's reasoning and identify potential biases or limitations.
