Re: ENSO Updates
Well NCEP models looks to be verifying here compared to the Euro. MJO likely to come out stronger over the IO vs the WPAC and now both the CFS and Euro models have stout trade bursts over the dateline.
The CFS depiction would put a big dent on El Nino chances for 2022:

So THIS is why it is showing La Nina lasting through summer 2022? I mean, if La Nina actually lasts through spring and summer without giving away to EL Nino I would be extremely shocked at this point but an interesting look at how the ENSO may evolve nonetheless.

I have to admit, I have been long expecting 2022 to be an El Nino year, but with these recent ENSO evolution dynamics, I am honestly starting to reconsider my belief on how likely El Nino truly is for this year.

Regarding the ocean component of ENSO, La Nina will be over soon since the surface temperaturs are likely to warm between March and April due to an erupting downwelling KW. But to get an El Nino you need a steady stream of warm water from the WPAC to the EPAC. The issue with a strong February trade burst and not a WWB, is that it likely means we won't see another downwelling KW forming and reaching the EPAC by June. So when the July trade winds go into overdrive, the lack of subsurface (and eventually the surface temperatures) warmth in place means an easier chance for -ENSO or La Nina to resurface by ASO.
This could change if we get a spring WWB over the dateline but it doesn't seem likely and those are rare without an El Nino transition in place.
It still seems the atmosphere is tilted towards La Nina. That's a big WWB over the IO.

Yeah I'm wondering what happens in March. You get a lot of El Niños really start then with a WPAC MJO event that causes a WWB. Still too early to see how it will be then. Door is definitely still open for El Niño but if there isn't a WWB by the beginning of spring then that door will start closing

Although this can easily change, the 90 day CFS still doesn't show a WWB in March-April despite that model's biases and the MJO probably moving into the Pacific around then.
This trade burst looks like it will spawn a pretty good upwelling KW. So it's possible that a even March-April WWB fails to offset it. I don't recall in our most recent El Nino fails in 2017, 2021 having strong trades like this in February.

If that verifies that odds of an El Nino go down I agree. I'm definitely keeping an eye on this beast of downwelling Kelvin Wave though. Perhaps it won't be enough to start an El Nino but if it survives, and so far it's doing a darn good job at doing that, La Nina is toast and neutral is more likely if the models verify in showing strong trades near the dateline. I just have a hard time trusting any models this time of year, it's easily my least favorite time of year due to the Spring Predictability Barrier. Who knows what will actually verify in terms of models.

Think it's a little early to be looking out there even with climate models but yeah if the CFS was correct it would certainly take down the chances. We shall see I guess. Seems even with the EWBs the warm pool is probably strong enough that this takes us back into neutral again. After that is anyone's guess

Re: ENSO Updates
If we follow the 1998-2001 logic, it is that we may not see an El Nino until 2024
But seriously, I really think these ENSO state model predictions are quite interesting. What's for sure, unless we get some 2013-like messup, assuming we enter neutral or *possibly* a third year La Nina, there's always that chance that we may be in for another wild Atlantic ride.

Re: ENSO Updates
Most triple Ninas also occur after at least moderate Ninos. 2019-20 arguably didn’t qualify as one to begin with

Re: ENSO Updates
The CFSv2 is showing what the trade wind pattern you DO NOT want if you want an El Niño. The ECMWF is more open to an El Niño. At this point, it is still too early to make a definitive call as to the ENSO state for the 2022-2023 winter.

Re: ENSO Updates
Credibility that these models have towards ENSO especially beyond the 45 time frame or so? Zilch.

Re: ENSO Updates
Unless we get another 2009 type El Nino that comes on super late in the spring period, the writing is on the wall for a 2022 El Nino. Yeah the models aren't reliable in this time period so we don't know what's going to happen in March, but that doesn't matter because we will see a month long February trade burst and not a WWB. An ideal situation for an El Nino was either a February WWB or simply relaxed trades. Not an uptick in trades.
To me this means:
1. La Nina atmospheric forcing is still in control despite the Nino regions eventually warming.
2. Likely upwelling favored and not downwelling for the next couple of months, a sensitive time for El Nino formation. So when this present downwelling KW is in the EPAC, it could be followed by a pool of cool waters.
It was tough anyway with a -PDO/-PMM regime.

To be fair there is a decent +PMM coming on, though yeah with the -PDO its westward extent is a little stunted. I'll keep my eyes on this but I'd say for the next few weeks the window for El Niño is wide open. Now in a few weeks if we're still talking about this and there isn't a coming WPAC MJO I'd probably agree it would be difficult. But as it's only getting in February there's still ample time for things to shift in El Niño's direction

The door for an El Niño has not closed just yet. It is not common, but there have been El Niño years that featured easterly winds in the equatorial Pacific. We are not going to know for sure the ENSO state of the 2022-2023 winter for a while.

Re: ENSO Updates
I still say we should reserve judgement on ENSO until the usual spring period. I do think this EWB is potent and sustained enough to where it could generate a UKW that may weaken the warm pool but not dispel it entirely. With the progression of said warm pool and what looks to be a developing +NPMM (a common occurrence after prolonged Niña episodes) the damage to La Niña is essentially done, it's just a matter of whether or not we stall again or we can eventually get some more WWBs down the road to herald a legitimate Niño.
