Pac yes, enso imo not as much anymore because I’m not convinced the pac pattern is driven by enso. It’s been identical for 5 years through 2 ninos, 2 Nina’s, and a neutral year. Hard to argue that is enso driven! Is the pac a problem though regardless of what’s causing it, most definitely yes.
Besides we can’t simply blame the Nina for ruining the -NAO. Nina history says that’s not accurate. Nina -NAO months in Jan Feb and March have actually been snowier then all other enso state -NAO months. Problem is a -NAO is rare in a Nina. This year was more the exception then the rule both in having a -NAO Nina and completely wasting it.
BTW side note: the one exception is obviously moderate to strong Nina’s with a -NAO. That’s the gold standard. Those are when we get crushed with snow. Yes a -NAO still correlated to more snow in other states but if you take weak Nina’s, enso neutral, and Nina’s while a -NAO does favor more snow then normal the numbers aren’t crazy big. And Nina’s actually has better -NAO avg snowfall then neutrals and weak ninos. Small sample size though since there aren’t that many -NAO Nina months.
