Part of it could be MJO propagation related too. Going to have to see what this newly emerged sunspot group does to the total number as well

Solar doesn’t match 2020 at all

I’m not thinking a 2022 level RNA, but I do think we average a solidly negative PNA DJFM

With the inferno SSTs from the western Aleutians over to Japan that’s no surprise

Yea, this is going to be a central based/CP Niña and we have clearly turned the corner with this event just in the last couple of days with a decided push starting. The chances for an official Niña as opposed to cold-neutral look way better now. The PMM turning negative with the rapid cooling off Baja, the very strongly negative PDO and the IOD turning negative only support this becoming a Niña further. I suspect there’s a drop in the MEI this month, unlike last winter where the PDO and PMM didn’t play ball and the MEI didn’t couple well, this one will have no problem

Yes he does. He goes very cold and snowy and says it’s extremely favorable for -NAO/-AO, a weak SPV and SSWEs every year. Even said that back in 2015 with a raging super El Niño in place. He has zero credibility IMO

With this look, my guess is that this month averages close a -3 PDO

Another possible correlation between high geomag and the Atlantic hurricane season:

Figured you’d accuse me of that, paranoia will destroy ya. No. 10-11 was -PMM. -PMM is most common during -ENSO. And it also correlates to a weak STJ https://en.m.wikipedia.org/wiki/Pacific_Meridional_Mode

-PMM taking shape…..rapid cooling off Baja since the tail end of August

We may be at the peak but it’s going to be a few months before we can know that for sure. We may see another spike or we may not. There are other sunspot groups coming up that can cause another spike or they may not. It’s wait and see. It’s impossible for anyone to know for sure right now. The total sunspot numbers for this month are still very high

The 01-02 solar max….final seasonal ACE: 110. And that was before AGW really took off like a rocket. Not a coincidence @Gawx

Pretty clear relationship between high solar/sunspots/geomag/radio flux and the Atlantic hurricane season:

Why not? What’s wrong with keeping on eye on the strength of the PAC jet in the months ahead since it has consistently been a huge issue for the past 9 winters

The never ending saga…

Going to have to wait awhile to actually confirm that but maybe…01-02 also peaked in August/September then slowly dropped through the end of March. That said, radio flux is still very high

Nice conspiracy theory Mark Margavage lol. It doesn’t frigging matter if it’s cold-neutral, the atmosphere is and has been in a strong Niña state. MAKES NO DIFFERENCE if the SSTs are cold-neutral. So no matter what the ENSO SSTs say it’s still going to behave like a La Niña with a strong -PDO. I can conclude that the SSTs are going to say that monkeys fly out of your butt and it’s still going to behave like a negative PDO Niña this winter. The twitter crowd can predict this being “east-based” all they want. Good luck to them with region 1+2 SSTs approaching an El Niño and region 3 warming up rapidly. Now, it looks like it’s going to be a CP/Central Pacific event. And good luck with the high Atlantic ACE fantasies, we’re now below normal. You’re going to be lucky to see the final ACE number for this season crack the low 100’s

@40/70 Benchmark I know you’re not considering ONI, but it looks like we are going to see some considerable warming with a WWB in the eastern to central ENSO regions. Region 1+2 is warming very quickly right now. That absolutely does not support an east-based event. Regions 3 and 3.4 are also going to see warming push in. I still feel like we may end up cold-neutral in the ONI sense, it’s very late for a substantial Niña event (SSTs) to take shape. Either way, this is going to be interesting to watch over the next 2 months

@bluewave It appears we are going to see a strengthening of the already strongly negative PDO this month. Warming is continuing in the northwest PAC near Japan and the western Aleutians while there is rapid cooling in the GOA, the eastern part of the basin along the west coast and off Baja (-PMM) This is not screaming -WPO, -EPO, +PNA to me. Furthermore, we’re at the time of the year where the trade winds begin to collapse over the equatorial Indian Ocean as the Indian and Asian monsoons terminate, we are going to see SSTs warming up across the maritime continent and the eastern IO and additions cooling across ENSO. However, a potent WWB is forecast across the central and eastern part of the basin which will likely warm up the waters even more. Also, a prolonged EWB will park across the western basin and maritime continent which would fuel a -IOD. -IOD/-ENSO is only going to enhance the background Niña circulation state and the Maritime Continent (MJO 4-5-6) convective forcing

Great find

For anyone interested, here is a very good write up by @Isotherm on geomag/solar and the NAO. Also touches on QBO and ENSO influences: https://lightinthestorm.com/archives/tag/solar

FWIW this is the new C3S snowfall projection for winter

@bluewave did a very good job of explaining why the PAC side did what it did in 13-14. Back in the fall of 2013, HM nailed the very strong +AO/+NAO that winter. He attributed it to the geomag, solar and QBO. The North Atlantic SSTs in the fall were kind of a good giveaway as to what was about to happen too IMO

Huge PDO configuration difference. There was a cold pool where the marine heatwave by Japan is now

Looks like a new sunspot region has just emerged, have to see what it does….
