2026-2027 Strong/Super El Nino

[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

Per RONI Nino 3.4, no Super El Nino was ever this low in mid-May. Might be Super per ONI and Strong, RONI.

We disagree but that’s what this forum is for…sharing different opinions. I think this El Nino’s RONI breaks the all time RONI record from 1982-83 and also ends up breaking the record traditional ONI since 1950

No surprise that the El Nino is beginning to couple with a westward lean close to the +30C warm pool.

EPS Days 11-15 looks nothing like May El Nino in the Pacific

We may be running back 23-24 as far as the Pacific pattern goes

The westward lean is closer to the +ENSO MJO 7 composite with the ridge from coast to coast. But notice how the troughs are weaker in the coming forecast near the Aleutians and Baja.

Similar to the weak La Niña this past winter when the ridge out West was stronger than the trough in the East.

While it may be too early to draw conclusions about next winter, this would result in a weaker Aleutian Low and possibly a weaker low in the Southeast like we saw in 2023-2024 and 2015-2016 relative to 1997-1998 and 1982-1983.

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?

We might need a +5c El Nino to get that North Pacific High area - low pressure strong and persistent anomaly like 82-83 and 97-98. Right now I think the North pacific 500mb pattern may match 23-24 going forward more than other Stronger Nino's

This is the first that the  +30C warm pool near the Dateline made it down to 100m in April with a developing El Nino. Notice how much warmer in all aspects we are than 2023 during the same time.

You have to wonder if this continues leading to a slower cold pool formation than we typically see toward the later stages of the El Nino in the Western Pacific. We probably wouldn’t know until next winter whether it could cause this one to wind down more slowly than usual during the spring.

The DWKW has started to surface and an “El Nino Costero” has developed off the South American coast in region 1+2:
 

 

^ Translation: “#El_Niño_Costero. Upwelling of warm waters along the central coast is evident, as is a significant increase in air temperature along the Lima coast, with temperatures today ranging between 26-31°C. SST anomaly reaches up to 5°C along the Lima coast.”

There’s no guarantee that any of that stuff happens as modeled. I think it’s increasingly likely we are headed toward another -PDO type El Niño IMO.

 Here’s the raw (rather than relative) anomaly for the daily OISST in Nino 1+2: ~+1.5C (relative is ~+1.0C)
