This paper applies the MID/QC substrate framework to Jupiter’s Great Red Spot, interpreting the long‑lived anticyclonic storm as a stable coherence structure anchored by torsion geometry and substrate‑level tension gradients. Rather than treating the Red Spot as a purely fluid‑dynamic anomaly, the analysis frames it as a persistent coherence well formed by the interaction of rotational shear, substrate polarity, and Jovian atmospheric stratification. The MID/QC model explains the storm’s exceptional longevity, boundary sharpness, and energy retention through substrate‑level mechanisms that supplement classical turbulence models. This includes the role of coherence wells in stabilizing large‑scale vortices, the influence of Jovian rotation on torsion alignment, and the coupling between atmospheric layers through substrate tension pathways. This work demonstrates how MID/QC provides a unified substrate‑mechanical interpretation of planetary atmospheric phenomena and extends the framework’s applicability to large‑scale, long‑duration coherence structures in gas‑giant environments.
