Preliminary Analysis of the Polar Landscape for Boreal Winter 2023-2024

https://easternmassweather.blogspot.com/2023/08/preliminary-analysis-of-extratropical.html?m=1

Perhaps, now people do understand. First you see Polar landscape, the second is extratropical which contains much more than polar. So the description of the link and what you get is not the same.

 

Who cares, it's an article and its title. Perhaps articles should include footnotes of definitions for every single word used too.

Yea, extratropical refers to much more than polar.

I see what you meant earlier, maybe I posed an incorrect link. This one works.

One of the links I posted connected to the polar blog entry, rather than the extra tropical Pacific, as advertised.

Thanks Ray, this solves the problem. I asked this, not just for me, but I share the link for the weather freaks on the other side of the Atlantic :)

Fortunately Ray does understand.

The primary analogs for the winter of 2024:

Key factors:

Enso state: El Niño

Enso strength: Super 

Polar region: unknown, but lean is +NAO due to the increasing solar activity and recent volcanic activity.

Pacific region: This is developing like an “old school” nino, starts in the east and moves west over time. The flip side of this is the nino will likely peak earlier in the eastern regions, and later in the western regions. I am leaning towards the peak being “too late” for eastern snow lovers, but the possibility of an earlier than expected peak needs to be watched. The PDO is expected to stay negative, but the region is rapidly warming. It likely averages in the neutral/slightly negative range, but could reach that via a moderate negative anomaly in Dec, slightly negative anomaly in Jan, and slightly positive in Feb and Mar.

Atlantic region: SSTs are warmer than average.

 

Top analogs: 1972-1973, 1991-1992, 2015-2016, 1997-1998, 1925-1926.

decent analogs: 1957-1958, 2009-2010, 1991-1992, 2019-2020

The best analog right now is 72-73, a classical east based (EP) El Niño coming off a La Niña, super peak, averaged -PDO for DJF. Polar region was a strong +NAO, which I believe this winter has a higher probability than usual for due to the unusual volcanic activity and solar activity. That is why I like 1991-1992, that winter was less driven by ENSO than I think this one will be (strong, not super), but it was a strong +NAO winter, which has been blamed on the extreme volcanic activity (Pinataubo eruption). This also was linked to the raging +NAO the following winters (1992-1993 and 1993-1994 were strong +NAO winters).

I would be shocked if this winter averaged out with a strong -NAO given the -QBO and the propensity for Ninos to have periods of blocking

Agreed.

.9" for me in southern Pa....

yes, you read that correctly.  

That has to be near record territory. You're not even right near Philly....inland north of Lancaster seems like getting less than an inch is record material....I wonder how much they got in '72-'73 or '97-'98.

Yes…I’d be interested in knowing that answer too?  Wow, under an inch for the whole winter season…that’s impressive.  
 

Man, I thought we had it bad last winter here with 12+ inches(which is horrible too), but under an inch is insane.

His rationale is all bogus...the volcano is a convenient excuse, but its not impacting us.

There is evidence suggesting that the Pinatubo eruption was linked to the strongly positive NAO winters of 91-92, 92-93, and 93-94. Other factors are unknown (Siberian snowcover, etc), but the known factors right now favor a strongly positive NAO. The solar correlation is weaker, but the correlation between the solar cycle peak and the NAO is a positive one, especially during Feb. Is a negative NAO possible? Of course, but right now, strongly a strongly positive NAO is favored. The last time we had a solar peak was I believe was the 2014-2015 timeframe. A possible wrinkle is that this solar cycle isn’t as strong as that one was, but the correlation worked well then with Feb 2015 being a strongly +NAO month.

Sure, a negative NAO is possible. Maybe I am overlooking something that I didn’t even consider that is a stronger driver than either of those things (solar and volcano). It’s possible, but right now I am leaning towards a strongly positive NAO winter (especially Feb). If I’m wrong, I’ll own up to it and admit it.

the Pinatubo eruption was much stronger and in the NH, shooting SO2 into the atmosphere... this one is weaker, in the SH, and shot water vapor into the atmosphere. they're different

the -QBO favors blocking, the strong Nino itself favors blocking, and solar research is out. some say the ascending solar favors blocking, some say it doesn't. but overall, solar and the eruption are dubious at best, and the -QBO and Nino are known to be blockier

so to say that a strongly positive +NAO is favored is a bit much

You need to actually read up on the volcanic implications if you are going to use it. Yes, it seems like it played a role in the strong PV that season, but that eruption was different on that it released a ton of SO2. This one was all water vapor. Pinatubo also had a drastic effect the very next winter....last season was a near neutral NAO in the mean (slightly positive) with two major episodes of blocking. 

There is not much of a signal for solar max....however, ascending solar is linked to negative NAO and descending is linked to +. We are still ascending.

Yeah…Pinatubo was the most climate-altering eruption since probably Tambora in 1815. 
 

The 1912 eruption in Alaska was bigger but not in the best spot to affect the global climate.
