so_whats_happening

I know it is still frowned upon discussing in this thread but when do we start throwing up some flags here on the Antarctic?

This is something to keep in mind are conditions capable to have this large spike, almost doubling of current SST's come fall time? Upper ocean heat anoms (not OHC) taking a bit of a nosedive and looking at the rest of the month trades will rule over most of the basin maybe that little potential will come the last week of July, still nearly 2 weeks away though.

Yea GFS is fairly similar in the approach the Euro has but still takes about 2 weeks to get to 6 where something may pop up. By now I would assume we would want this more into 7/8/1 with the little pokes of MJO activity to help cause this positive feedback. Still have plenty of time of course and things will surely change in the next week but as of now this week or so looks rather mundane overall. Hope we do see some overall improvements and move this subsurface warmth out of just the EPAC.

Sorry but im not seeing the MJO wave showing up yet. I also really wouldn't take a forecast nearly 2+ weeks as gospel we have seen how this worked out with the last potential MJO wave/ -VP forecast from end of May for middle to later half of June. This had looked like an appreciable event that would kick things in motion once again and while we did see a minor spike in temps (~0.1) increase in 3.4 it was not enough to really warrant the solid wave that was forecasted by models at the end of May beginning of June. Now if we start to actually erode a fairly Nina like atmosphere I could agree but Hovmollers over the next week and SOI present a different picture muted warming potential and even cooling looks to take place over 3.4 maybe even 3, as we see 4 has taken a dive. There is a chance that by the end of the month for a little peak, and I mean little as of right now, into phase 6 before going null again could be from a tropical system trying to get going in the WPAC but overall things are dead. I assume this is the MJO wave in talks?

The 30 day SOI is just about near 0 when back in end of may beginning of june we had a monthly SOI near -20. There has been quite the string of positive days from the deeply negative two weeks we saw. Doesnt look to be a big change to that coming up here either. July not looking like a stellar month.

Appreciate it. For some reason HM was not clicking that was anthony.

HM is henry marguisity? Probably butchered the last name. Anyway hope he moved away from his hype train years ago with the constant big daddy talk. I enjoyed his analysis from time to time though. Never saw him as more than a synoptic/mesoscale guy for east and mid atlantic.

Same areas as mentioned still will be under the potential of warming coming up but models seemed to have backed off much appreciable warming potential which makes sense based off the lack of an MJO impulse. Should lead to a slow incline as we move into July as of now. Speaking of MJO should still be wondering around null for a bit may try to poke out in 2-4 for a brief moment.

We should see a nice spike coming up here in the beginning of July. With lack of MJO im curious what the full effects will be. Thing is the weakening in trades is a bit further east than the last time so maybe a more pronounced warming in 1+2, 3, and maybe getting a bump in 3.4 at least in the most eastern portion.

Again to my point above it is not a perfect evolution and honestly seeing things happen 1:1 would be incredible to witness at some point (im sure at one time things of similar evolution have happened). Here is the 2009 evolution again anomalies are off but it has a similar look thus far with warming and the extension of the warm tongue staying out west for quite some time until fall and winter. Maybe we see a similar idea and maybe this is why some models are showing a crazy peak? Time will tell of course.

Feel the lack of subsurface cooling in the WPAC is really playing a role in keeping a lid on things combined with a still prominent -PDO pattern (this does look to be weakening over time now). Here is CPC May to mid June subsurface again the EPAC is now more anomalous than the now near CPAC warm anomalies in the subsurface. Again not say we cant see a rather decent reversal in the WPAC but to what extent and when does this occur? Most El Nino events that I have access to (until 1979 for subsurface) show we already would have had a negative anomaly in the WPAC by now. 2009 subsurface had this in some similar evolution, this year albeit is definitely stronger anomaly wise but the evolution is rather interesting to follow.

Evolution of course will never be the same but we can get some clues from past instances to maybe help out with future forecasts. This is a gif of 1997 subsurface evolution and 2023 so far, definitely have shown a longer gif before of the 97, 15, and 23 (so far) evolutions before. You can see yes there are similarities the warmth extending from WPAC to EPAC but the biggest difference and curious how this plays out, the warm pool not being nearly as strong as 97 comparing WPAC to EPAC gives me pause at what this outcome could actually be. In 1997 we saw the subsurface have warmer anomalies than the eastern portion before the whole thing went full tilt and caused what we know. This go around the EPAC warm pool is warmer than the subsurface waters now coming from the WPAC. I wonder if this will play a role in less umphh behind it as it does eventually push east? We also still are not developing the classic cool/cold anomalies in the subsurface we have seen with numerous El Ninos of past. I wonder is it possible we have pushed the heating potential limit and now we start to see the move westward of surface temps as we weaken trades in 3.4 which will continue to warm, sort of like a slow bleed as we head toward Fall. We have about 2 weeks until we get to see the results of the June 2023 subsurface. Going forward the trade wind halt and even slight reversal should provide another bounce up come mid July latest. What happens after that may be another fun one to watch barring this forecast for reversal is correct.

Thats what i have been thinking for awhile now. We get things going quick and slump around peak season depending on how everything with the El Nino evolves. I honestly hope El Nino conditions take over or it has the potential of being heck of a season.

I dont normally post stuff from twitter but when reading about the developing tropical storm(s) in the Atlantic I happened upon an interesting take to the El Nino discussion. Considering we may have a rather stout +SOI pattern setting up lets see where we end up. Lack of tropical activity still in the WPAC and EPAC, Atlantic may begin firing off storm after storm coming up here all while the MJO is set to be dead for the next week or two. MJO forecasts show maybe a re-emergence around 1/2 but not until the first week of July, if forecasts hold.

You can see why the warming had taken place the lack of trade winds really allowed the area to just open up so we got that spike. While the trades have maintained if not even dropped temps locally during this time. We can expect temps to hold or slightly cool until things lighten up or if a warming occurs in 1+2, 3. More of that needs to be prevalent for the Nino to really start to show onto those higher numbers. Average should probably end up around .75 maybe .8 on the month of june unless we see a more drastic change to end the month.

That looks like fun!

Honestly will have to wait and see. We might not get a reaction until July which a few days is semantics of course. We also need to see just how influential the WWB will actually be. If we take this last one for example which was still a rather impressive event we rose a solid .5 degree not shabby at all but since have cooled that area by half the warming that occurred. Im still hesitant on going anything above 2C as that would require more robust WWB events and an actual dislodging of the subsurface warm pool. We have about 4 months until we hit peak typically seen with El Nino events. At the rate we have been going it has been about .3C increase each month since February. If this rate continues we look to be about .9-1.2 for July average, 1.2-1.5 August, 1.5-1.8 for September average and maybe if we arent on the cooler side of things pushing near 2C in October. Thoughts are definitely pinned around 1.7-1.8C in 3.4 currently so while we push into strong territory the atmospheric response may be more on the moderate Nino side of things. We seem to be on the 30 day kick for WWB events with larger pushes happening every 80-90 days (late february/early march and late may). Lets see how it goes.

Got some decent trade winds setting up over the next week. After that may be a wash to know how it finishes, after the 20th. As of now there does seem to be a potential WWB event setting up starting about the 20th lets see how the models progress this coming up. Also we finally see a potential in the EPAC for a tropical system but not much in the way of development based off models. This is a bit of a late start for that basin lets see how things go in the next two weeks and as we move into July the strong El Nino years tend to really produce.

Still surprisingly nothing crazy to report on in the Arctic but the Antarctic is just not doing good at all...

Yea I feel it may just complicate things even worse than they have been. We see how the impact of reducing aerosols in the mid latitudes is going we are seeing some of the of the warmest readings in oceans and atmosphere in our recorded history. If we dropped the aerosols all together boy are we in for some heating. If we cut back on GHGs it wont be an immediate response of course but it will be better in the long run of less warming potential being placed on the system than if we continue on this path. Methane and water vapor ruling the day on the short term aspect of warming.

To compare to the previous impressive WWB event back in Feb-Mar that had the insane MJO wave with it.

Sorry been on vacation the last week. This is by far the most influence we have seen from the WWB. The trades almost reversed completely across 140-90W. Lets see if we have more in the pipeline.

I had seen these in looking around but Gensini site looked to have old data besides the CFS forecast which seemed to update. The other didn't quite match up with the tweets snowman had posted on page 27 or 28 I believe it was.

Does anyone have a site to get GWO charts or data?
