    “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).”

    And this will spawn another DWKW

    ^ “#ElNiño is taking over the global atmosphere. We're gonna get a brief spat of trade winds over the East Pacific due to an Equatorial Rossby Wave, followed by another large WWB as the MJO traverses back into the Pacific. Models are showing low-frequency forcing setting up over the East/Central Pacific. Looking like a very strong, classic, coupled, canonical +ENSO event starting.“

    The subsurface continues to boil…. The cold-biased CDAS for daily Nino 3.4 SSTs:

    Modeling starting to show an ERW coupling with the MJO induced WWB at the end of this month as it moves across the PAC, enhancing it….

    If this traditional ONI projection is correct, we would not only set a record for the traditional ONI since 1950, it would also set a record for the new RONI. If we assume the RONI lags the ONI by .05C to 0.6C and the traditional ONI peaks at that level, it would very easily beat the highest RONI on record since 1950, which was 1982-83 at +2.5C ^ “Well, after looking through the climate reanalysis on SST anomalies dating back to 1980. If the Preliminary SSTs get confirmed. We are now ahead of the 3 most famous El Niños on record. 1982-1983, 1997-1998 & 2015-2016. Again, I'm not kidding, we are running about 0.18 °C higher. This El Niño has a very high ceiling with a possible peak in November & December of this year of 3.5-3.9 °C above average. Not only that, there is a slim possibility that SST in the Niño 3.4 region may hit a new all-time record of 29.9-30.0 °C, which is 85-87 F.”

    Let’s see what the westerlies/WWBs, +IOD and TC’s do over the next few months….how far east do they push that warm pool?
  14. snowman19
    This coming high amplitude MJO push into the PAC as we go into late month, coupled with an ERW is going to cause another massive WWB and a continued strengthening of this El Niño into June. A super El Niño is inevitable at this point and very likely a top 3 super event
  15. snowman19
    Maybe, maybe not. We aren’t going to have a good idea where the forcing will actually set up during the winter for several more months. For now, so far, this event looks a lot more like 1997 than it does 2015

    Out of the last 4 “recent” super El Niño events (1972, 1982, 1997, 2015), this one matches 1997 the closest, by far. Although this one is warmer in the subsurface than 1997 was. It looks nothing at all like 2015 at this time in either the subsurface or the surface. The DWKWs have just begun to surface at the coast of South America over the last couple of days. This one is certainly following a classic east-based/EP progression…..
  17. snowman19
    Agreed. Considering that is only the forecast through October and it will still be strengthening/warming at that point (the models have it peaking in November/December), with the added warming, it would almost certainly tie if not beat the all time RONI record since 1950, which was 1982-83, with 1997-98 being the 2nd. And it would also beat the record traditional ONI since 1950

    +IOD development. And it’s going to be off to the races….
  19. snowman19
    Yes. The next WWB late month is modeled as being amplified by an Equatorial Rossby Wave (ERW), which would trigger another DWKW and another big subsurface and surface warming push into the EPAC. If so, we would see a bunch of TC’s develop like the models are starting to advertise, causing more westerlies behind them, in their wake
  20. snowman19
    I completely, totally disagree. This Nino is already extremely well coupled and looks nothing at all like a La Niña

    A classic east-based event is unfolding as the Kelvin Wave begins to surface at the coast of South America along with the associated thermocline/sea level response ^ “Sea Level and Equatorial Waves 09-May. In the context of the precursor signals of El Niño, a Kelvin wave has begun to arrive at the coasts of Ecuador. Among its first effects are the rise in sea level (20 cm), deepening of the thermocline... “

    The CFS just continues to go higher with the peak: And building upon what LakePaste just posted, extreme (super) El Niño events offer better forecast reliability with their very strong ocean-atmosphere coupling:

    Agree. We are very likely to be into a super El Niño (over +2.0C) by September, if not August
