Researchers investigated the internal workings of the Aurora machine learning model, which is designed to emulate atmospheric dynamics. Using techniques like spatially pooled PCA and layer-wise relevance propagation (LRP), they found that the model's latent space is primarily organized by seasonal cycles, rather than distinct clusters for extreme storm events. LRP analysis indicated that Aurora attends to features corresponding to the 3D vertical structure of historical storms, and perturbing these regions significantly degraded forecast accuracy. AI
