2026-2027 Strong/Super El Nino

^ Regarding region 1+2: “We haven’t seen anything like this since 1997” -

You don’t know what you’re looking at that’s why you think there is no resemblance to 1997. Also, wishcasting -
2026-2027 Strong/Super El Nino
snowman19 replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
This event is very well coupled and looks much different than 2023. It’s also developing as the most east-based/EP El Niño since 1997 ^“The low-frequency (or "background") El Niño circulation is really showing up in recent runs of subseasonal guidance, with anomalous rising motion forecast to set up and persist across the East-Central Pacific even as the MJO signal keeps moving. The low-level response to this will be persistent westerly wind anomalies at low levels (helping the event to mature and grow to peak), and the upper level response will be increased westerly wind shear across the Western Hemisphere tropics due to outflow from the convection. Really looks like a classic coupled strong El Niño event setting up, in contrast to something like 2023 which had a much more muted atmospheric response.” -

IMO the Niña-like MJO (IO) forcing comes to an end with this El Niño once the +IOD gets established. The standing wave Nino/+IOD forcing combo is going to cause the eastern IO SSTs to upwell and cool off, causing subsidence in that region -

Yea, this one is developing as a “Costero”/coastal (east-based, EP) El Niño event. According to the South American Mets, we haven’t seen anything like this since 1997 -

From a South American Met: ^ Translation: “This is the magnitude of how deep—and therefore how long-lasting—the warming of the ocean floor near our coasts is. We're talking about 100 meters or more in its most significant part and nearly 500 in its verifiable depth. All that warm anomaly is advancing toward the South American coastal edge. There's little the APS can do, as noted (APS=South Pacific Anticyclone) We haven't seen anything like this since 1997. This is one of the reasons, perhaps the most relevant one, why there's so much information about a major #ElNiño event on the horizon.” -

I don’t think the RONI has any problem at all achieving super status. +IOD development is common amongst all the big time (super) El Niño events, i.e. 1997…… -

+IOD incoming, which will constructively interfere with the developing El Niño and will help to enhance the equatorial westerlies. I think this is the combo that finally sloshes the Indo-WPAC warm pool east…… -

@40/70 Benchmark Gaining more confidence this El Niño breaks the 1982-83 RONI record (+2.5C). Also think the ONI peaks solidly over +3.0C -
