Keep in mind that models tend to overdo ENSO strength at this phase.
And we also had a strong Nino just 2 winters ago. Historically, it would be unprecedented to have another strong one so soon.
Lol. The significance of QBO/ENSO polarity degrades to near meaninglessness if ENSO amplitude is weak, though.
So this comparison only applies if we enter a healthy moderate or strong niƱo regime. Otherwise subseasonal/intraseasonal variability will dominate.
