Quick question. Has data ever be compiled of the various states of teleconnection drivers during our most severe winters. For example MJO, ENSO, QBO, GWO, NAO, AO, PNA to name a few and then other factors collated and compared such as sea ice extent, snow coverage across Eurasia in October, SST anomalies, SSW and general stratospheric variables. If every one of these teleconnection drivers were known in addition to the other variables mentioned and calculated to produce a composite could this not be an effective way to compare with past years and help us to produce a long range forecast?
