1. Why are you using 1991-2020 for climo for a 1987 summer? That diminishes the above normal H5 in the E US on your 1st map.

2. The highest height anomalies/warmest temp annomalies are in the E US, regardless. How is that El Ninoish?

The negative height anomalies near the Gulf of Alaska, together with the core of the strongest negative height anomalies over northeastern Canada, look reasonably Nino-like to me. Summer ENSO teleconnections are much weaker and noisier than in winter, so I wouldn't expect a textbook composite. Given that, the broad pattern still seems fairly consistent with a mature El Nino.

Closing in on +4c in Nino 1+2

Let's do a comparison as things stand currently wrt SST's. Here's this year followed by the other strong/super el nino's going back to 82-83. Below is this year currently, followed by the others in reverse chronological order. Obviously, the globe is getting warmer over time. Naturally, sst's would follow suit. Is anyone disputing that fact anymore? I don't really see anyone doing that but not the point of this post. One can clearly see things warming over time. 

 

I've been floating around on these boards for a very long time now. There used to be discussions from very wise mets in the enso threads of yore on how actual sst's should be viewed and pondered. Not only the anomalies. So I'm posting the actual sst's as comparison. Looking at it this way, 97-98 and 87-88 stick out to me a little more so than the others. Again, not because of the actual readings compared to each other. Rather, the positioning of the warm pool biased east.

 Hot off the press from another source posting the 8/1/26 Cansips run of Nino SST anomalies. It is continuing the CanSIPS run trend of moving the strongest warm SST anomalies further and further east at the ~Nov peak. That’s not surprising because I’ve been suspecting a Modoki bias for it based on the past few years of analyzing it as I’ve posted a number of times here before.

 The April-June 1st runs had the warmest anomalies near the Dateline/straight Modoki (W based) in the peak month of Nov. Then the July 1st had warmest anomalies in Nov further E near 160W, more of a cross between central based and Modoki.
 

 The new Cansips run’s Nov peak shows the warmest anomalies centered near 130W, which would be centered in E Nino 3.4/Nino 3 making it pretty E based. Though this run is not as E based as 1997-8, stay tuned to future runs because the E trend of the strongest anomalies on Cansips from run to run may very well not be done due to this suspected Modoki bias.

 I can’t post it because the file size is much too large for me to have room in my account. But when it comes out on TT and WxBell, those will be smaller files and thus postable.

No one thought it was right with a straight Modoki in the seasonal mean.

The maps I was basing my post on were from weathermodels.com and were using 1991-2020 for base climo.

 But since I posted that, the WxBell Aug 1st version came out. It uses 1981-2010 for climo. WB had the warmest anomalies centered in Nov near 180 for the April-June 1st runs and significantly further E (near 160W) for the July 1st run. WB (using 1981-2010 base) has its Aug 1st Nov warmest centered near 150W, which is C based/basinwide and not E based like weathermodels.com’s (1991-2020 base) 130W. So, the WB 1981-2010 base version also moved E, but not nearly as far as the weathermodels 1991-2020 base version, which has it all the way E to 130W (pretty E based):

WB 7/1/26 SSTa run for Nov (1981-2010 base) centered ~160W

WB 8/1/26 SSTa run for Nov (1981-2010 base) centered ~150W

It's bad enough current SSTA vary from different products/sources, now we have models prog depictions following along. No wonder there's rarely agreement on forecasts...or on this Board! Lol

I think these changes are entirely immaterial with the degree of warmth throughout ENSO.

Why does the CANSIPS have the El Nino continue to be centered so far west? That's not the way it's developing or is now. +6c in Nino 3.4 is pretty extreme. Nino 1+2 is currently twice as high as Nino 3.4.

OHC is at a new high on this graph:

Now it will be interesting to see what happens from here. Looking back at 1997-98 we see there was a double peak for 180-100W OHC. 2015 we also saw this and 2023 again both years did have overall less OHC than 97 and this current year but both had a double peak, 1982 did not just had one continuous upward movement. My own thoughts would suggest maybe a September peak in OHC then a quick decline as we head into winter. The only problem with this is the lack of - anomalies in the WPAC subsurface we have yet to really see develop compared to other years with a similar temp profile. So as 180-100W may die out the overall 130E-80W and even just 160E-80W still stay relatively warm with those stronger negative anomalies not showing up leading to a more basin wide setup as we get to winter. Just thoughts floating around as we typically see the Nino events die west to east from an OHC stand point.

Yea this one will be fascinating to watch unfold. The atmospheric pattern still resembles that of a La Nina/ -PDO mode in the northern hemisphere for sure. 

Even with the tropical activity in the WPAC this year (which is great to see) we haven't seen many recurving typhoons sinlaku was the closest to still being a typhoon while recurving. Most of the storms have still been tracking west which doesn't bode well for the PDO to flip, maybe we see that change as we get into fall.

I would like to add more context I guess, it is nice to see some actual recurves still taking place even in a weakened state of a storm the energy injection is still important. I do wonder though if this means yet again an overall weaker Aleutian low potential for winter, time will tell of course.

Interesting to note that each of these events were immediately followed by a strong la nina (1998-2000 and 88-89).
