2026-2027 Record-breaking El Nino

I don't know how you can emphatically cite how much MC influence there was in 2023, then dismiss any influence of the central basin this season....yes, El Nino is stronger, but it's not omnipotent, as evidenced by the PDO resistance owed to the Japanese warm pool.

Anyway, we'll see what happens....good chatting, as always.

The Sep of 2026 MJO has been very different from that of Sep of 2023:

Sep of 2023 (blue): all in MC/IO

 

Sep of 2026: none in MC/IO

No doubt...the issue is whether it will be virtually all eastern Pacific, or some intervals of central Pacific influence will be at play.

 Here in the SE, I prefer either EPAC or CPAC dominating it to the MC dominating because that would normally mean a much reduced influence of the SE ridge/colder overall.

I think we all would take anything over MC forcing, which is the worst.....another thing to think about is if this El Nino is strong enough to pull all of the forcing east, as Chris seems to imply, then that would eradicate any MC influence....which he has stated in the past has acted to accentuate the warmth in recent El Nino events relative to past events, so this season could end up a bit cooler due to that....lots to think about. A bit of MC influence could leak into central forcing, but not east.

 Were in another very long -SOI streak, 47 days!

 Wow, the WCS daily PDO continues to plunge back down as it’s fallen to -1.74 in the midst of a record strong El Niño! How is this happening? It was -1.10 just 5 days ago.

Despite how strong this El Niño gets its influence over the pattern will be restricted due to the fact that it’s not coupled. Expect a wide range of variables with the overall pattern this winter.

A couple of guys online, Ryan Hall and Mark Margavage, seem to think the -PDO could have a colder influence in the east because the monster GOA low that triggers the huge Pac jet may not be. I don't think that make sense....-PDO/El Niño is worse heights are higher in the se and any cool ENSO influence is like a Modoki La Niña constructively interfering with east-based El Niño, so the any Aleutian riding would likely not be poleward. 

Weenie-logic. I'm with Chris on that.

Yeah it’s not as simple as “if I have competing cool ENSO influences, I am subtracting from the super El Niño which makes the pattern better for the east.” By that logic, 2023-24 should’ve been cold but it wasn’t. I am actually disappointed that the -PDO keeps dropping further because that’s bad for us. Although I still maintain that the PDO won’t really matter so much in a season like this either way.
