2025-2026 ENSO
Stormchaserchuck1 replied to 40/70 Benchmark's topic in Weather Forecasting and Discussion
It's because it's not overpowering other forces. If we had an El Nino at +5c, there would no doubt be a trough in the North Pacific. -
Daily PDO is hitting -3.4, they say that's the lowest daily they've ever seen. Last October the daily peaked at -3.0, and it resulted in a -3.8 monthly for October 2024, the lowest monthly reading on record going back to the 1800s.

Does anyone know that the top global sea-level pressure correlation during an ENSO event is actually NW of Australia and in Indonesia.. it's a total global-tropical phenomenon.. that >0.6 correlation in the equilateral-Atlantic is impressive, too. -

El Nino favors cooler waters in the mid-latitudes where the Hadley Cell meets the Mid-latitude Cell... it's the opposite of what we have now from Japan to north of Hawaii -

Yeah, the subsurface is weak right now. It's not a perfect predictor, but it has led by several months for the last few years. -

Usually you like to see the subsurface colder if an official La Nina is to emerge -

They are colder than I am for ENSO the rest of this year, but they probably have good reason with models coming within range. -

I'm surprised that they favor a La Nina over ENSO Neutral for the rest of this year, just based on the ONI.. I guess they expect cooling in the coming months, along with seasonal models. SOI last year never went strong positive when a lot of things were pointing to a Moderate-Strong La Nina early in the year, and it ended up being an accurate predictor, per ONI it never even went La Nina last year. The SOI has been positive, July could be 10 months in row, although only slightly so, so I guess they are thinking it will accurately predict again. -

I didn't see the post. Do you have a link? -

This year, climate models seem to support a cooling of ENSO in the coming months. The SOI has been a good gauge for a few years now.. it has been positive for the last few days. A positive July would be the 10th straight month with +SOI, which would be a la nina or cold enso indicator. The subsurface was really warm in the western subsurface in the spring, but has since neutralized.. so yeah, maybe near neutral, or slightly cool for the rest of this year. -

I'm starting to think the odds of an El Nino next year are lower, but higher chances 2 years from now (27-28).. maybe a Weak El Nino next year -

For the 2nd point, I'm explaining the relative ENSO index. Since the whole globe is warming, it maps ENSO relative to that global warming skew.. so I'm saying that if global SSTs are +0.5 warmer on average, if Nino 3.4 (the strongest correlated ENSO region of the 4) is +0.5, that is actually even with the global skew, or "0.0". It's called the RONI, and in the last 20 years the RONI has had better correlation with the northern and southern hemisphere Hadley Cell pattern (-PNA) than regular ENSO (ONI). -

I actually found that in the last 33 years our warmest Winters for the whole US have been in east-based El Nino's albeit, rare as they are. I think that means in the coming time El Nino's, and east-based El Nino's may happen with warmer Winters. -

In the coming time, there will probably be 60% El Nino's, or +20% more than La Nina's.. it's just really interesting that after the 97-98 Super El Nino the opposite occurred. That's probably not a sustainable pattern though, and will probably switch in the coming time. That's why they have also developed the "RONI", which is relative average compared to the global warming (if global warming is +0.5, and Nino 3.4 is 0.0, that's a -0.5 RONI). -

Global warming is associated with a stabilization of the Earth climate.. less low pressures/wind, more high pressures. Since the Tropical Pacific is associated with strong winds as an "average", cooling the waters as much as 3-5c along the equator for "neutral" compared to areas north and south, then an El Nino, and actually strong El Nino, is a stabilization of that system. This is not what has happened since 1998... we have actually seen cold SSTs relative to the global warming on the order of 4-5 standard deviations below normal during that time.. the thought is that more El Nino's will happen in the coming time to even this system out, as a product of global warming. However, the last 27 years is a very interesting datapoint because something is causing an opposite pattern.
