    Very impressive for that area.

    The current record breaking +1.81° is well ahead of what any of the models were forecasting for this month.

    Interesting post about the SOI with how east based this event is becoming. I am conducting an interesting experiment due to the fact that this El Niño is exceptionally east based weighted, so much so that it has actually caused sea level pressure anomalies to shift slightly eastward. This in my amount of studying and research shows that this might be skewing the traditional Troup SOI index which is ran traditionally from Darwin, Australia to Tahiti in the central Pacific. so the new index still uses the same formula and is ran from Darwin in Australia, but here’s the difference it now runs to Nuku Hiva island, which is almost 700 miles northeast of Tahiti, but in a latitude since it lines up pretty well with Darwin, which gets this a better result. I found that the SOI in my research and studying was around 10 to 15 more into the negative compared to the traditional index. The picture below really tells the difference on August 28. I used the Tahiti to Darwin formula which is a traditional version which is still used by BOM. But today on 29 August, I used a different formula the Darwin to Neku Hiva and found that the -19.85 really matches well with what we’re seeing right now as far as a sea level pressure anomaly dipole. I’m hoping meteorologists that find this post useful will hopefully help to diagnose the strength of this El Niño true its true colors. So if you all can leave a reply below this post and let me know what your thoughts are. That would be absolutely helpful because I believe this will better assess the true strength of this El Niño event and future ENSO events.

    There are papers discussing changes to the teleconnections like the NAO and AO as the climate continues to warm. Bigger swings from one state to another. One of the best papers actually came out a year before the biggest swings began in the NAO and AO in 2009-2010. That is more the exception than the rule since most papers only come out after the change had already occurred.

    According to most of us on this forum. But the majority of the population movement is to places like the Deep South and Desert Southwest like Phoenix. Just go on YouTube and pull up videos about how people in these areas stay in the AC as much as possible in the warm season. There is a couple on there that used to live in Minnesota that would rather deal with Phoenix summer heat than Upper Midwest winter cold. They adjust their summer routines to only go outdoors early in the mornings for more than a few minutes to avoid the heat. But to each their own. This world provides a wide array of climates to accommodate everyone’s wants and needs.

    Sample sizes in a rapidly shifting climate will never be as large as they were when we were on a colder and more stable temperature regime prior to the 1980s and 1990s. Thresholds are a common part of systems like the climate which can have non-linear elements blending with more familiar linear ones. But the models aren’t advanced enough to know exactly where these are ahead of time. Most of the time a crossed threshold is a rear view mirror assessment. This is what so many climate studies come out after the fact instead of before. The post I responded to said the coldest stretch since the 1970s.

    Yeah, the winters in the Northeast and across the CONUS really warmed following the 2015-2016 baseline temperature jump. Last winter was our first colder winter against the long term means since 2014-2015 in the Northeast. Almost seems like the 2015-2016 caused more of a non-linear shift than something gradual. So it will be interesting to see what things look like following this significantly stronger El Niño. Getting 3 baseline increases from 2015-2016 to 2023-2024 and now 2026-2027 is very extreme for such a short period of time. We had to wait 18 years from 1997-1998 to 2015-2016. Now we are getting our first super El Niños only 3 years apart. Matches with the findings of the recent corals studies showing stronger El Niños as the climate warms.

    The cold in the East this past winter was weak sauce compared the the hard winters of the 1970s.

    Within the U.S. this is true since we have widespread access to air conditioning. Most of the movement within the U.S has been from cooler locations to warmer ones. Outside this forum most people applaud the much milder winters since they require less heating demand which has become so expensive these days. They will put up with warmer summers since the extra cooling costs are less compared to what a really cold winter like we would regularly get in the past did to winter heating bills. But the movement to warmer locations within the U.S comes with risks. Water shortages are becoming an issue out West with some smaller communities losing water rights. Wildfires have become a big issue with the land becoming so dry combined with human and natural ignition sources on the rise. Another risk is that over the coming decades is that the Western droughts begin to creep out into the Plains lowering crop yields. Places like France and The UK with much smaller agricultural output have suffered significant crop losses this summer. Plus increasing exposure to extreme flood events across the U.S from rainfall and tropical systems.

    Last season was the best this new much warmer climate could do as compared to the 95-96. More warmth was a factor in the NAO reversing so quickly in March as corals studies have found bigger NAO and AO swings from one state to another as the climate has warmed. Much less available cold made last winter the 2nd warmest for the CONUS.

    You are talking local patterns and nuances more than the actual strength of the event. The last event in 2023-2024 jumped the planet to a new higher global temperature baseline with a relatively weaker RONI. The Nino ridge was among the strongest on record with the warmest winter in record for the CONUS and much of North America. It’s debatable whether the weaker Aleutian low was a function of RONI or just a symptom of weaker upper lows in general over the years with both La Ninas and El Niños. Notice this past winter with a weak La Niña configuration closest to 1995-1996 the ridge overpowered the pattern with smaller 500 mb lows.

    NOAA and other agencies maintain both the ONI and RONI. The paper it’s based on developed it more for marginal events like weak La Ninas and El Niños where the WPAC warm pool was extending more influence than the Nina regions. This was not specifically designed for higher end El Niños or La Ninas.

    RONI is a relative metric to other areas of SST warmth. It’s not a realistic gauge of how strong the actual El Niño event is. The planet doesn’t care about relative metrics as the global temperatures are setting records every day now with how extreme this event is becoming.

    Urban spots away from the seabreeze made it to 10 days reaching 95°+ again. This has become a common theme in recent years. In the old days we would get cooler summers in between.

    New OLR record for so early in an El Niño as this becomes the strongest east based event for the date. In recent days, the warming has intensified off the coast of #Ecuador and northern #Perú. It is there that @enfenperu measures and assesses #ElNiñoCostero. From an atmospheric and oceanic perspective, OLR values are at historic lows for this time of year in the central and eastern Pacific. This is evidence of coupling between the ocean and the atmosphere. The depth of the warm waters to the west of #Galapagos (the last point where we can compare all events), the volume of warm water clearly exceeds that of 1997, while those of 2015 and 2023 were much smaller. This sheds light on the robustness of the event in the eastern Pacific.
