Researchers have introduced Dandelion, a novel neural network architecture designed for simulating planetary dynamics on spherical surfaces. Unlike traditional models that struggle with spherical geometry, Dandelion utilizes a warp-based approach, predicting tangent-plane displacements and transporting features along great circles. This method avoids convolutions and achieves spatial mixing through spherical coordinate transformations. Dandelion demonstrates strong performance across a suite of challenging, natively-spherical PDE datasets, often outperforming existing spherical architectures, particularly at higher resolutions. AI
