After the current brief, temporary period of cooling with the easterlies in 3.4, here comes next round of warming/WWB/DKW/-SOI

El Niño already affecting the long wave global pattern:
-
-
We can keep using the persistence argument/forecast but eventually that doesn’t work anymore. Patterns are bound to change, they can’t stay the same forever, especially after almost 10 years
-
-
Right, however, now that we have this strong El Niño event developing, coupled with a very healthy +IOD, my thinking is that this may be enough to finally break the IO and Maritime Continent MJO phases. We will have to wait and see
-
Once the +IOD gets going, it’s going to produce strong subsidence over the IO and the Maritime Continent. That should effectively kill the “Niña-like” MJO wave phases
-
Yes. That upcoming WWB means business. So does the developing +IOD, which is going to constructively interfere with the El Nino and you can kiss the La Niña like MJO phases goodbye

The new Euro is showing a strong +IOD developing. It’s going to constructively interfere with the El Niño. I think these MJO attempts are about to change in a big way
-
The new Copernicus model run just came out today….add that to the growing list of models showing a very strong El Niño by fall
-
Likely very temporary with another major -SOI onslaught and WWBs coming. Once these TC’s start forming in the Eastern Pacific, it’s only going to increase the westerlies/WWBs behind them as they move away
-
The El Niño atmospheric response is increasing
-
I’m not talking about him. JB said it’s turning into a Modoki
-
Anything is possible and we will see. I am however very confident that this is not becoming a Modoki like some other people are wishcasting

Region 1+2 is blazing again, up to +2.6C and climbing, region 3 is at +1.2C and also climbing. This event isn’t just east-based, it’s extremely east-based. And there’s yet another Eastern Pacific WWB/downwelling Kelvin wave
-
Classic Eastern Pacific (EP) canonical El Niño. The east-based warming/WWBs/downwelling Kelvin waves just continue to get re-enforced through Bjerknes feedback:
-
-
@Bluewave The new GEFS is showing a strong WWB in the EPAC (regions 3 and 1+2). Another big warming coming in that area? I think this event is going to be known for its WWBs and downwelling Kelvin waves in the EPAC breaking on the South American coast
-
The thing is though, every Nino in history has weakened during northern hemispheric winter. Every Nino on record normally peaks in November/December then weakens in Jan, Feb, Mar. If that’s what this one does, it would be perfectly normal and expected

ENSO region 1+2 warming again…almost up to +2.5C. Region 3 up to +1.2C and climbing…https://www.tropicaltidbits.com/analysis/ocean/nino3.png https://www.tropicaltidbits.com/analysis/ocean/nino12.png

@Raindancewx is on board too
