But is the WAR really something new? And have we seen this feature be predominant for an anomalously longer stretch? Like a decade or more?
If the enso phase shifted and we were snowy with a Nino, for ezample, would any of us really be talking about WAR and SER and troughs not aligning the way we like? And before you get to "but marginal Nino events don't work for us anymore", can you answer my last question?
I don't think it's a simple answer wrt the pattern. I do think a massive chunk has to do with enso however. With that said, I also think we tend to over complicate things at times.
