Makes sense considering how I expect December to unfold....look at the EURO .....+NAO.
Cohen is just having an impulsive outburst, which people are prone to do on social media.
I don't agree with you that the forcing doesn't matter....at least in stronger events. But obviously +PNA seasons are more difficult to come by in the heart of a multi decadal cold phase.
I don't just mean the numeric value of the index...the pattern itself was very anomalous and augmented by the fact that even the +PNA interval in January was biased so far west that it acted as an extreme RNA.
I'm not arguing the point that seasonals have Gross limitations....just that last season was an anomaly that wasn't really predictable on a seasonal level.
My LICSW mind sniffs out some jealousy of the career he has built and insecurity about this own professional standing...people act overtly aggressive like that when they feel threatened and inadequate.
