Its pretty self explanatory......IMHO those are the best matches using a combo of ENSO intensity and distribution of warmest SST anomalies. I mean, we are mainly referencing "anomalies" when speaking of sensible weather, so I don't see why the end result should be much different. I def. would shy away from using very potent la nina as analog seasons, given that ENSO may not be as a pervasive driver due to AGW.
