At the same time, NOAA reports very low solar activity and weakening coronal-hole high-speed-stream forcing, while NASA’s forecast shows the extreme wind anomaly peaking and then fading as 100-hPa planetary-wave forcing rises. That sequence fits the Pattern Nexus solar–stratosphere hypothesis, but the wave-forcing signal means this is a test of causation, not proof.
