Are you enjoying this 25 years of -PNA. What I find interesting is since 1998, the Southern Hemisphere is holding the same Hadley Cell pattern, even when ENSO has been Neutral or El Nino. That makes me think we are in a La Nina decadal state, vs what is commonly thought of as -PDO (it's not perfect, but as a general signal it stands).
Doesn't mean it isn't -PDO, but the forcing is definitely coming from Nino 3.4.
So have you been able to take advantage of these extreme -PNA Winter's? I remember talking to you a lot back 15 years ago, and you did pretty good with -PNA predictions back then. You were saying it was more of a pattern than I was picking up on at that time.
Look at this composite for Feb-March 2018 to 2024, the last 7 years:
The previous record for a 6-year consecutive period was +95dm over the NAO region 1964-1969, and that's just for a 1-month time period (January)! We are blowing that out. Even without the global warming skew, this 7-year RNA is still near record breaking. I don't see why it shouldn't continue this Winter.. I have found out that the ENSO subsurface correlates to the N. Pacific pattern more than surface SSTs! You see this connection clear through 2024 so far as it's been a Moderate-Nina in the subsurface, and we've had -PNA conditions
..While the surface has been Neutral to El Nino. If you historically test it back, it's not perfect but it does work better than SSTs a lot of the time.
We had some really extreme -PNA in December 2021, when it broke +600dm on the daily. And then February has been ridiculous -PNA since 2018, but that actually first started showing major anomalies in Feb-Mar 2009. So in my opinion, the cycle is still peaking. At the very least, it will take a little while to ramp it down. I just wonder if there have been good results in the NW Winters relative to the index..
At one point Ozzy Osborne was seen as the greatest threat to Christianity since Lucifer himself. Kind of makes me wonder if conservatives 50 years from now will be totally repping drag shows.
