The content introduces a novel method for decomposing flows with multiple transports, extending the shifted proper orthogonal decomposition. By optimizing co-moving fields directly and penalizing their nuclear norm, the methodology improves separation and accuracy in describing transport phenomena. The study includes numerical comparisons against existing methods on synthetic data benchmarks and showcases the separation ability of the proposed methods on various flow scenarios.
