I guess you consider DT a know nothing peon….
-
Yea….ooook….ummmmm…..sure……
-
The flip to +PDO seems to be starting and the extreme warmth in region 1+2 is migrating west into region 3….

It’s going to be truly frightening when we see a strong to super east-based Nino in full force this fall . I’m actually looking forward to experiencing one, I was too young for 97-98
-
This background state makes me think that once the WWB hits this Nino is really going to go into overdrive and take off, our background state now is way warmer than 1997 and 1982 and even 2015

Thanks for your very insightful, knowledgeable and riveting contributions to serious discussions as always. I would expect no less

I don’t even consider using analogs from the 1800’s. Our climate background is nothing like it was back then, night and day with the AGW (much warmer) climate of today. So far, as you pointed out in your other post, this one is developing as a textbook Eastern Pacific/east-based El Niño
-
I would expect it to stay that way (east-based and strong to possibly super) due to Bjerknes feedback. Once that feedback loop gets established, the SST warmth is self-sustaining and even magnifies. It has been shown that Bjerknes feedback is stronger and more sustainable in the eastern ENSO regions. This event has developed as a classic Eastern Pacific (EP) El Niño and there’s no reason to doubt it stays that way. See this study: https://www.nature.com/articles/s41467-022-33930-5

Another new model run showing an east-based strong event…

It doesn’t matter if it’s east-based or basin-wide once it gets to super status. There’s no such thing as Modoki/central pacific super Ninos, they are either Eastern Pacific or basin-wide. 15-16 was a basin-wide super event and it was a torch. We got lucky with one storm that winter
-
I’m more interested in what the ultimate strength of the El Nino is. If it goes super (+2.0C or above), it will be a very, very easy winter forecast…..blowtorch…just like 15-16, 97-98, 82-83, 72-73 were. Then all you can do is pray for a real lucky, well timed snowstorm when you actually have cold air, like 1/16 and 1/83

The Euro seasonal has an extremely east-based/Eastern Pacific (EP) canonical El Niño:
-
Correct, however, the POAMA (BOM) and CANSIPS are both showing similar outcomes
-
-
If the El Nino is that strong and east-based like the Euro Seasonal is showing, that outlook makes no sense. It’s going to strengthen the tropical Atlantic trade winds and there will be wind shear from the PAC galore. At the very least, it would shut down the Caribbean
-
-
Also, 97-98 was -QBO, like this year…. And although it didn’t come off a Niña, the 96-97 winter was cold neutral ENSO
-
A late November peak sounds about right. The 82-83, 97-98, 15-16 events all peaked in late November
