Models are showing low-frequency forcing setting up over the East/Central Pacific. Looking like a very strong, classic, coupled, canonical +ENSO event starting.” I like focusing on where the +30C warm pools are. Since the actual forcing driving our sensible weather follows those areas. The current forecast is for split forcing centers near the Dateline and off of Mexico in late May.That Dateline forcing is closer to near record Nino 4 and MJO 7 and the forcing further east is with the record +PMM. 1 Link to comment Share on other sites More sharing options...
Stormchaserchuck1 Posted May 14 Author Share Posted May 14 That's what I am saying about 1997, Nino 4 has warmed a lot year-to-year since then. It will be interesting to see if it resembles west-based Nino characteristics or if the warming in Nino 4 is something else. Link to comment Share on other sites More sharing options...

Yeah, we had the split forcing in the 2023-2024 El Niño with the record warm pool near the Dateline and another center off of Mexico like we are currently seeing. The 1997-1998 El Niño had very east based forcing since Nino 4 was so much cooler. 2023-2024 was more of a full basin event rather than an east based one like 1997-1998.

40/70 Benchmark Posted May 15 Share Posted May 15 2 hours ago, snowman19 said: If these record-breaking traditional ONI projections of over +3C are correct and the RONI continues its trend of lagging the ONI by 0.5, 1982-83, which was the strongest super El Niño on the RONI (+2.5C) since 1950, would be the closest RONI analog. Again, assuming these ONI forecasts for over +3C are correct, we would easily tie, if not beat 82-83 on the RONI Only issue is that the RONI ls lagging the ONI by more this go-around, even though it is like to reach or exceed that absolute value of 1982.

Only 1991 had a May RONI +0.5 to become a Super Nino, all the others were averaging ~+0.8 by now. 1 Link to comment Share on other sites More sharing options...

My educated guess is that the current/daily RONI equivalent is ~+0.5 although like the ONI it is always moving, of course. 2 Link to comment Share on other sites More sharing options...
Stormchaserchuck1 Posted May 15 Author Share Posted May 15 It will probably go Super, I just don't think it will be an all time record breaking event on the RONI. Were also not seeing a +PNA, or -NPH in the next 15 days. 1 1 Link to comment Share on other sites More sharing options...

You can see the general outline of the May El Niño 500 mb composite taking shape with alterations probably due to the competing marine heatwaves. The coming near to record May heatwave forecast for the East next week is much warmer than we typically see with such strong developing El Niños. Stronger Southeast ridge could be a function of the weaker RONI relative to ONI and more general subtropical ridging adding a more Niña-like flavor to the mix. The May Western North America El Niño ridge is located a little further SW than usual with the weaker Baja trough than they typically see. May 4th to 11th strong Nino ridge in SW Canada and Aleutian low north of Hawaii Forecast May 18th to 25th Link to comment Share on other sites More sharing options...
Stormchaserchuck1 Posted May 15 Author Share Posted May 15 ^The main correlation is in the NE Pacific and it doesn't look anything like it through the end of May. In June and July the ENSO-500mb correlation is weaker, but May is usually a pretty strong month, even with developing El Nino's. Link to comment Share on other sites More sharing options...

snowman19 Posted May 16 Share Posted May 16 “This signature actually looks quite similar to 1997, just delayed by a couple weeks. 1997 had a similar "break" in the westerly anomalies for a couple weeks due to MJO forcing, followed by a big WWB in mid May. This year seems to be following suit just ~2 weeks later (similar to how it's been evolving overall).” 2 Link to comment Share on other sites More sharing options...

In June and July the ENSO-500mb correlation is weaker, but May is usually a pretty strong month, even with developing El Nino's. The developing El Niño isn’t the only thing going on now. The early month pattern with the more +PNA was closer to what we typically see with the May correlation. But this coming heatwave is more related to the MJO 4-6 convection pumping the Southeast ridge. The +30C wam pool extends all the way back to the IO. 1 Link to comment Share on other sites More sharing options...
