Planetary Resonance, Middle-Stratospheric Wave Bifurcation, and Non-Markovian Boundary Memory: A Multi-Level Diagnostic Prognosis for Boreal Winter 2026/2027 via the Standardized SDI–BI–CI–EI Framework

Classical univariate teleconnection metrics systematically fail to capture the non-linear, vertically stratified, and sub-seasonal coupling between middle-stratospheric momentum deposition and lower-tropospheric boundary conditions across the Euro-Mediterranean corridor. This mon...

Decoupling Stratospheric Wave Geometry and Eurasian Blocking: The SDI–BI–CI–EI Suite and 86-Year ERA5 Master Database (1940–2026)

Classical univariate teleconnection metrics (e.g., NAO, AO, NAM) frequently fail to capture the non-linear, vertically decoupled dynamics governing the Euro-Mediterranean winter and sub-seasonal weather extremes. By artificially projecting complex atmospheric states onto single-l...
