Once the monsoon is gone, it’s all systems go time for the Nino. Good bye trade winds. IMO we will see the strong WWB and DWKWs you speak of. Here comes the +IOD assist

Correct, literally all the models show regions 1+2 and 3 remaining warmer than regions 3.4 and 4 right through January

As I mentioned above, the +IOD just officially got going on the new update (+0.79). Early next month, the monsoon circulation ends in the eastern hemisphere and that’s when this El Niño should get going and start really warming up. The end of the monsoon should kill the trade winds off in the central PAC and that’s when the WWB/DWKW activity begins in earnest

@GaWxRegion 3.4 is now over +1.4C on the OISST

The +IOD regime has started, jumped up to +0.79 on the new update

After about the 1st week of September, the monsoon circulation in the eastern hemisphere should completely collapse and that’s when the trades should fall apart/reverse and region 3.4 warming should really take off in a big way

If that reading isn’t a “glitch” in the OISST given the warmer CDAS and CRW, it’s not going to last long with the strong WWB ongoing in regions 1+2, 3 and eastern 3.4….

The BOM warm bias this year has been with ENSO, I haven’t seen the same bias with the IOD

Very good explanation of why this Nino is staying very east-based/EP

It’s projected to stay positive through January: http://www.bom.gov.au/climate/ocean/outlooks/#tabs=Graphs&region=IOD

This Nino has been defying all the “rules” on how it’s “supposed” to develop for the last 6 months. Since March, we have been hearing about how it’s going to fail, collapse, not get any stronger than weak, nothing like this has ever happened before, it defies logic, we might go into a neutral/La Nada, it makes no sense, there’s no past precedent for it, it’s not developing anything like previous strong and super El Niños, the trade winds are killing it, the subsurface is killing it, the forcing is killing it, the PDO is killing it, the -PMM is killing it, the configuration makes zero sense….yet here we are on 8/19, way, way past the spring barrier with region 3.4 almost at official strong (+1.5C) status, region 3 at +2.0C and region 1+2 at over +3.0C and every new model run getting warmer and showing a super El Niño developing this fall

When there is an overwhelming ENSO signal (strong/super El Niño), it’s not hype, it’s going to alter the global heat budget and have a very profound effect on the global longwave pattern. In the absence of an overwhelming signal (weak/moderate Nino or Niña), then other factors may end up overriding it so to speak

I have no comment on snow, it’s too hard to predict because one storm like 2/83 or 1/16 in a super El Niño can skew the numbers. That said, if there’s an ONI of over +2C, I don’t see a cold winter (Dec-Mar), especially given AGW. If we do in fact get a trimonthly super peak as the models are showing, I just can’t imagine any month with -2F, -3F, etc. negative departures in the Mid-Atlantic or Northeast. The STJ is going to flood the CONUS and Canada with maritime PAC air, it would be a raging firehose. The south may see -1F departures due to solar irradiance from constant raging STJ cloud cover

Actually I wasn’t talking about you, not sure why you felt the need to attack but whatever. And I haven’t given an opinion on where I think the forcing will be other than saying “wait until November”. I have however given my opinion on the ultimate strength of this El Nino which I believe will be a solidly super ONI peak for NDJ. As far as these climate models, I would err on the side of caution given their monumental, epic fail for the 19-20 winter. I will never forget the non stop climate model hype that summer and fall of the historic winter and historic blocking, cold, snow, that was coming for the east coast, boy oh boy was that a bust for the ages

I have a feeling the people who think the forcing is just going to stay pinned like a statue exactly where it is right now for the next 7 months because some of the climate models say so and show what they want, may be very disappointed come December…..

We are going to have to wait until November to see where we stand obviously, but assuming ENSO region 3.4 goes super as all the models now show, and we get a healthy +IOD event, I would be shocked if the forcing doesn’t move east. How far east? Who knows. 3.4 going super is going to dramatically affect the global heat budget and something is going to have to give. I can’t imagine seeing La Niña forcing just staying in place given that projected setup. But again, let’s see where we are 3 months from now

The new dynamic model average is for a super El Niño, as GaWx already posted. The average is a super trimonthly ONI peak for NDJ. We have consensus….CFS, CANSIPS, EURO, BOM, JMA, UKMET, MeteoFrance…all unanimously show a super Nino now

Right, it seems region 3.4 is going to be the western limit of the Nino warming. All the major warming/warmth being shown is concentrated in regions 1+2, 3 and 3.4.

Not surprising. The strong WWB is continuing in the eastern and central Pacific right now and you also have this: https://x.com/jnmet/status/1692559270028456417?s=46&t=NChJQK9_PUjA1K7D2SMojw

Those years were all super El Niño years. The new BOM update has the international average of models showing a +2.3C peak for NDJ

One thing is for sure, IF we get to early November and there’s a super Nino or one is imminent and IF there’s canonical El Niño forcing, I’m going torch. I don’t care what the MEI or the Macaroni index or the CANSIPS or any other seasonal model says at that point given those 2 circumstances. Again, IF. I remember all the people who got burned really bad going for a cold winter back in 15-16 with their “west-based super Nino” and “west of 1997” wishcasting (ie. JB, Judah Cohen, etc). 15-16 was one lone snowstorm in a sea of unending warmth. As far as snow, I won’t go there because one rogue, lucky, thread the needle storm can dump in super Ninos

Yea, regions 3.4, 3 and 1+2 are all warming. 3.4 and 3 are the warmest they’ve ever been on both OISST and CRW. Region 1+2 is about to warm above +3.5C again, Region 3 is about to go above +2.0C and I would not be surprised if region 3.4 is strong (over +1.5C) by 8/31 on both OISST and CRW, it’s around +1.4C right now. https://x.com/jnmet/status/1691820815447151076?s=46&t=NChJQK9_PUjA1K7D2SMojw

This is the 1st time I’ve ever shown the Coral Reef on here you vapid little airhead. The OISST is over +1.3C you fool. It’s almost as funny as how you keep posting the CFS showing region 1+2 plunging into a La Niña over and over for the last 5 months in a row, meanwhile it’s warmed to historic levels. Troll. And I know you have 2 accounts on here, your other alter ego is “Thunderbolt”. You’re not even smart enough to do a good job covering it up

Either way, it does appear that we may well be into a strong El Niño by the end of this month. Coral Reef Watch has region 3.4 up to +1.44C and warming

The atmospheric coupling has already started. Also, looks like the models are getting stronger with the +IOD https://x.com/jnmet/status/1691820815447151076?s=46&t=NChJQK9_PUjA1K7D2SMojw https://x.com/jnmet/status/1691820815447151076?s=46&t=NChJQK9_PUjA1K7D2SMojw
