Re: ENSO Updates
Lack of Sea level heights over the WPAC shows that there are currently no new signs of a downwelling Kelvin wave or any warm anomalies propagating west to east:

Re: ENSO Updates
Despite its La Nina calls and it showing a long lasting period of above average trades over the EPAC, the CFS continues to show an atmospheric El Nino standing wave persisting over the dateline:

This is why it's not always wise to simply ignore the SOI just because it doesn't fit the reasoning, it's trying to tell you something. In particular the long version of it. There are numerous metrics, but to isolate one metric over the all of them as a whole trying to signal something is not the best way to go about it. Take a look at the recent CCKW crossing the CPAC/EPAC. It has origins of rossby wave action in the mid-latitues near and about Australia. Completely missing the Maritime Continent (WPAC got nothing out of this) but expanded, exploded over the IDL and will weaken once it hits the Atlantic/Africa. What the divergent data from the CFSv2 is telling us, is that more action like this will continue emanating from the SOI domain, and that the mid-latitudes are not simply reacting but can also play a role.

I wonder if this is seperate from the kind predicting a La Niña. It can't be disagreeing w/ itself this much

This post was probably an opinion of mine, and in no way is official. Please refer to http://www.hurricanes.gov for official tropical analysis and advisories.

Yeah certainly. Great way to put it. The MC and Australia have been a driving force. Yesterday's 00z Euro run shows no signs of this activity slowing down and continues a negative leaning SOI. It's showing Tahiti's pressure rising to near 1015mb for the last 7 days of July, and also pushes Darwin's MSLP to near 1015mb.

Something is off. It's like it's not coupled properly.

Re: ENSO Updates
Despite all of the above come Monday's official weekly reading will lower again. Would not be surprised if it came in anywhere from 0C to 0.2C

Re: ENSO Updates
The SOI may be negative but that is NOT the look of an El Niño. We may stay below +0.5°C in Niño 3.4 for a while.

Ocean at best resembles Modoki El Nino and even those warm anomalies are not near Nino 3.4.
So ocean is neutral and atmosphere is El Nino is what I'm currently gathering. Very funny. This is once in a long while scenario.

Yep, and Nino 3 also down to 0.0C, dead neutral.
Nino 4 is the only one remaining warm, staying at +0.9C

I read a few posts that while the ocean has cooles a bit, the atmosphere still shows some el nino behavior. So lets say the ocean continues to cool into the cool neutral range. What are the chances we have a slightly cool neutral ocean with a slightly el nino like atmosphere?

I doubt that will happen, either it stays warm neutral or the atmosphere eventually reacts to the cooling of ENSO. IMO.

Re: ENSO Updates
What does El Nino Modoki type II mean? (I didn't even know there were two types.)

Re: ENSO Updates
If I remember correctly, the ECMWF did well with ENSO in 2015, 2016 and 2018, but was way too warm in Niño 3.4 in 2017 and 2019. 2017 was an especially bad forecast bust for the model.
