raindancewx Posted February 12, 2020 Share Posted February 12, 2020 Here is the European update for ENSO - looks to me like no real change in Nino 3.4. The predicted decline in Nino 4 has been shown for several months now and is much more interesting. The Jamstec site is changing looks like, so might be a little late to update this month. Long term, the pattern still appears to be cycling through at about a 104 day lag. I had a storm exactly 104 days ago yesterday in October.

raindancewx Posted February 18, 2020 Share Posted February 18, 2020 Weeklies continue to show decay in Nino 3.4. It's hard to say if it will last - the subsurface animation is down. My suspicion is it won't.

The two are opposite temperature signals for the US in March in large areas of the US. On the monthly data sets, February 1990, 1992, 1995, 2015, 2019 are similar, but the AO wasn't super positive in January in these years generally. The Oct 16-Nov 15 pattern has shown up, shifted West for February, so I'd expect Nov 16-Dec 15 to show up for March, shifted in some way. The warm storm forecast for me late this week is on track with the warm/wet storm on November 6th, roughly a 3.5 month lag still, generally +104 days, +/-3 is verifying pretty well. 1 Link to comment Share on other sites More sharing options...
raindancewx Posted February 20, 2020 Share Posted February 20, 2020 In an SOI sense, a big -SOI in Dec, near 0 SOI in Jan, and then a big -SOI in Feb is fairly unusual. This blend is broadly consistent with my analogs - with a warm West for March. 2012-13 is objectively the closest match in the past 100 years, but I prefer this blend. Year Dec Jan Feb2019 -6.7 0.7 -7.3 1953 -5.8 5.0 -5.2 1980 -2.2 2.1 -4.2 1980 -2.2 2.1 -4.2 1987 -5.8 -1.5 -6.2 2002 -13.4 -2.0 -9.3 2002 -13.4 -2.0 -9.3Blend -7.1 0.6 -6.4 For the subsurface, 100-180W, 0-300m down, these are likely top matches for Dec-Feb: 100-180W Dec Jan Feb 2004 0.79 0.52 0.59 1992 0.19 0.27 0.28 2001 0.17 0.95 0.78 1992 0.19 0.27 0.28 Mean 0.34 0.50 0.48 2019 0.34 0.51 0.50 Take your pick for March - the second blend is much closer to the analogs I used for Spring (1954, 1993, 2005, 2019 for MAM), and March 2020 (1954, 2004, 2005). 1981 is actually a decent match for the subsurface too. March 2013 also looks fairly close to the left map, and it is the top SOI blend. Link to comment Share on other sites More sharing options...
raindancewx Posted February 23, 2020 Share Posted February 23, 2020 Waters below Nino 3.4 aren't as warm as last year, but I can't really see a rapid collapse in Nino 3.4 temperatures either, at least until April. Warmth in Nino 3.4 in March is a strong warm signal for the US later in Summer, especially August-September. Probably not as warm as last Summer though, which followed one of the warmest Nino 3.4 Springs on record, I think it was 7th since 1950 for warmth.

raindancewx Posted February 25, 2020 Share Posted February 25, 2020 We're likely warm enough in February now (27.1C or so), with enough warmth below Nino 3.4 for this event to be classified as an El Nino.

The subsurface does imply Nino 4 may cool soon, fairly rapidly, in which case the AO may take over completely. Link to comment Share on other sites More sharing options...
UniversesBelowNormal Posted February 26, 2020 Share Posted February 26, 2020 I wonder if the Nino 1+2 stuff is just reflecting of the current warm pattern... and if ENSO will make a reemergence. It looked like we were going El Nino, may still go weak El Nino. Link to comment Share on other sites More sharing options...

raindancewx Posted March 1, 2020 Share Posted March 1, 2020 Subsurface for Dec-Feb, in the 100-180W zone at the equator, 0-300m below the surface, is like a blend of 1992-93 (x2), 2001-02 (x2), 2004-05, 2014-15. Of course, that blend featured a cold East/warm West. https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/ocean/index/heat_content_index.txt The closest objective year for the subsurface was 1985-86 - a very hot West to merely warm East in March.

More interesting to see the lack of cold in the blue zones, but that's likely because most El Ninos are followed by La Ninas. The pattern in February is pretty close to what I had for whole winter (warm coasts, cold interior NW, through the Rockies and southern/central plains, but not into MT, ND, SD) but unfortunately it came too late.

raindancewx Posted March 30, 2020 Share Posted March 30, 2020 Despite CPC kicking and screaming about calling this an El Nino, JFM will once again be at least +0.5C in an ONI sense, for the fourth trimester. If April doesn't fall below +0.5, it becomes an El Nino officially. CPC uses 27.2C as the Nino 3.4 baseline for average in March. March should be around 27.8C. Since the numbers are rounded, April probably only needs to hit +0.35C for this to be considered an El Nino event, as that would be enough for +0.5C in FMA. Subsurface heat content for 100-180W is still around +0.5 in March too.

The_Global_Warmer Posted April 1, 2020 Share Posted April 1, 2020 Winds continue to favor pushing the near surface layer West at a faster rate (0-75M). This will slowly decay the warm layer near the surface East of 160W. While a cool pool tries to develop around 160-140W towards the SA coast. Gently sloping from 150M-75M subsurface(160-130W) sloping towards the surface in the nino 1-2 area. 150-180E/W looks to gain heat subsurface. 1 Link to comment Share on other sites More sharing options...

Its pretty likely FMA will be warm enough to make this an El Nino, as Nino 3.4 is still pretty warm. It's still six weeks early for this to be final for the West, but here is an early look at how well my snowfall map did - big bust for the big cities in the NE, but even there I had New England near average. Pretty happy with it overall, for something issued in early October. High mountains in the Rockies, NW were snowy, TX/mid-south generally below average, save West Texas. California was snowier than expected. Midwest was generally snowy where I had it - Dakotas, Missouri, Nebraska, Illinois, etc. Been pretty happy with my Spring Outlook so far too.

The_Global_Warmer Posted April 10, 2020 Share Posted April 10, 2020 In the short term 120w to the SA might see the cold pool knocked down a bit because of favorable winds. But West of there the winds become anomously stronger Easterlies. This will allow the growing cold pool to get closer to the surface and grow in size. 1 Link to comment Share on other sites More sharing options...
raindancewx Posted April 10, 2020 Share Posted April 10, 2020 The JISAO PDO value is in for March 2020 - Nate Mantua sent it out today. -0.82 is lowest in a very long time - since October 2013 https://oceanview.pfeg.noaa.gov/erddap/tabledap/cciea_OC_PDO.htmlTable?time,PDO Link to comment Share on other sites More sharing options...
raindancewx Posted April 10, 2020 Share Posted April 10, 2020 Also, the European has Nino 3 warming quite a bit the next few months, with Nino 3.4 in El Nino conditions in April. The decay of warmth is forecast to be roughly west to east, with 4 dropping fastest, then 3.4, then 3. 1 Link to comment Share on other sites More sharing options...

Maestrobjwa Posted April 14, 2020 Share Posted April 14, 2020 On 4/1/2020 at 1:53 AM, raindancewx said: Canadian has given up on a La Nina for 2020-21. New run is on the left. Would probably be a -0.3C winter given what it shows. Previously it had a La Nina developing June-July, now it kind of has it developing in August and ending pretty fast. And I hope it does end fast (or better yet not happen at all! ) Sorry, MA bias...lol Link to comment Share on other sites More sharing options...
raindancewx Posted April 16, 2020 Share Posted April 16, 2020 The AMO (+0.363) for March, and PDO for March (-0.82) combination is the worst possible outcome for the Southwest to get a lot of precipitation long-term, especially if a La Nina does develop. The ideal is a -AMO, with a positive PDO. We're opposite that now. I'm still pretty skeptical of a La Nina. Nino 4 is real warm for a La Nina to develop. I think it needs until June to fall to average warmth, even with rapid cooling. Link to comment Share on other sites More sharing options...
