  "abstract": "Recurrent high‐speed streams and corotating interaction regions (HSS/CIRs) are common solar‐wind drivers, but their influence on Schumann resonance (SR) frequencies remains poorly quantified. We analyzed 173 threshold‐defined HSS/CIR proxy onsets using superposed epoch composites, bootstrap uncertainty, and a month‐matched random‐epoch null model. At the polar Hornsund station (corrected geomagnetic latitude 74.16°N), the apparent first‐mode SR frequency exhibits a positive response on days 0 to +1 relative to onset and is unlikely under the month‐matched random‐epoch null. A similar positive response appears at the high‐latitude Ivalo (65.14°N) and Rovaniemi (63.69°N) stations, with the same ordering under matched‐support restriction. Event‐level scaling with baseline‐relative Kp, AE, and Vsw impulses shows the clearest organization by Kp, consistent support from AE, and a positive but less diagnostic relation with Vsw. The Kp/AE organization strengthened after excluding ICME‐overlap events. Overall, HSS/CIR proxy onsets are followed by a small but repeatable first‐mode SR response that is statistically supported, reproducible across high‐latitude stations, and organized more clearly by geomagnetic coupling than by solar‐wind speed alone.",
