  1. Mixed research results using the Top Down Approach since the 80s..some of the more recent research points to a larger connection between solar wind cycles and QBO effects over the Southern Hemisphere when comparing DJF. If you take that data and combine it with the QBOEM data on the reversal of QBOEM effects flipping in spring..makes me wonder if the Earths tilt is causing a propagation of influence between SH/NH (basically the closer tilt to the sun, the greater the solar wind influence).

  2. Singapore station is where most of the data is collected for the QBO research. Most of the current research is focused on the MC (with a correlation showing QBOEM enhances convection there while QBOWM suppresses it). My question is what is the effect of other areas outside the MC and since we are in QBOEM is it also helping to enhance convection basin wide (which only helps create more interference). Something else that is interesting is the data shows QBOEM has the exact opposite effect on the MC during spring/summer when compared to boreal winter..there is zero understanding as to why.

  3. Agree, if the RMM is having issues locating the actual MJO, then LR modeling will continue to have these back and forth flips. Still think the modeling is rushing the flip a little bit (even if the MJO loop is tighter). Interested to see if Webb's theory on the Modoki can form..just another piece to the puzzle lol.

  4. If the MJO is stalling due to the convective interference, then it should have a sharper loop and continue eastward. But with it being masked...the RMM could mistake the convection for MJO impulse..overreacting and taking it on a bigger loop into 4/5 before correcting. Sent from my SM-S767VL using Tapatalk
  5. There's also research showing this interference convection can impede the MJO (slowing/stalling it)..once the interference begins to subside, the MJO can quickly finish its propagation eastward. Sent from my SM-S767VL using Tapatalk
  6. Would have to loop satellite back to where there was a clear signal of the MJO and filter out the other convective flareups (while still following the MJO eastward) to see where the MJO truly is. Webb refers to it as Kelvin waves...but research considers it generated from OLR generated from Rossbys. Webb could very well be correct on how this plays into generating some type of Modoki during La Nina like conditions..or he could fall flat on his face. There's just not enough research that has been completed in this area..the recognition and studies for Rossby/OLR masking MJOs have only started to be completed in the last year (and there was still a lot of unanswered questions in those studies)...same with the QBOEM's influence in enhancing the MJO as it propagates over the MC.

  7. Research data was presented at an AMS Con that lends support to what was presented in the RMS data. If I remember the paper and slide correctly, basically the OLR from Rossby waves can create flare ups in convection along areas we typically consider MJO areas. It gives the RMM a false sense that the MJO is in a different location, but in reality it had been propagating eastward (just weaker than the convection created by the Rossby/OLR)...basically the MJO is masked. That's the issue with taking the RMM verbatim...we are just at the tip of the iceberg as far as understanding QBO/MJO/Rossby/OLR interaction, still need tons of funding for the research needed.

  8. That is QBOEM...the Easterly winds have taken over at the mid latitudes, while the westerlies have weakened to near zero. As the stronger easterlies propagate downwards, QBOEL when the easterly wind is strongest in lower levels, the westerly wind will flip at top and start increasing (as the lower easterlies begin weakening (QBOWM). The cycle of the QBO. QBOEM has research data supporting the QBO have a greater influence in helping the MJO increase convection over the MC. Sent from my SM-S767VL using Tapatalk
  9. What the GEFS does to the EPO past truncation is both sad and hilarious at the same time...a 12 point spread on a 16 day forecast. May as well throw blind darts at a spinning dart board lol. Sent from my SM-S767VL using Tapatalk
  10. That was the MJO forecast on Jan 7, 2015 to Jan 28, 2015. All models (and reality) torched that Jan. I remember the cliff diving was very high...then Feb happened. The pattern flipped Feb 7. Nov 2014 also featured a cold spell similar to this year. Feb 2015 delivered the cold and snow east of the MS. Torches like 2018 feature a PNA that goes severely negative in Jan (-500 or lower), and so far that's not appearing in the LR modeling. Point is it's still Mid Dec and no reason or sign to even form a line to the cliff..yet. Sent from my SM-S767VL using Tapatalk
  11. If would have seen this MJO forecast on Jan 7...would have cliff dived...yes or no Sent from my SM-S767VL using Tapatalk
  12. I agree...think the GEFS is jumping the gun on the cold flip. Will be interesting to see if the EPS starts noticing anything in the 2/3 week of Jan. I think Feb will be interesting for the forum as it unfolds.
  13. Would I cancel winter...um no lol. Here's some data why (also fits with Carvers thinking of a back loaded winter). This is for TYS going back to 1910, and also supports why last year is completely different than this year. Comparing the temp data set from every year, only 7 currently correlate with this year when comparing low temps (this year Nov: 19, Dec: 27 barring a flip in modeling to end the year Dec will be closer to 23-24 as coldest recorded low). Years with a similar +4 or higher spread from Nov to Dec (late Jan/Feb relation): 2014/15...Flipped Cold 1970/71...Flipped Cold 1959/60...Flipped Cold 1956/57...Continued Warmth 1950/51...Flipped Cold 1922/23...Flipped Cold 1911/12...Flipped Cold So 6/7 (86%)...had a flip to cold. Compared to last year (coldest low Nov: 21, Dec: 21...no chg). Winters where Nov to Dec had a +1/-1 variance: 2018/19..Flat trend/Warmth 2012/13...Flat trend 2011/12...Flat trend 1994/95...Flipped Cold 1991/92...Flipped Cold 1987/88...Flipped Cold 1979/80...Flat trend 1967/68...Flipped Cold 1940/41...Flat trend 1938/39...Flat trend 1928/29...Flat trend 1921/22...Flat trend 1913/14...Flat trend So 4/13 (31%) only had some sort of cold pattern reshuffle.

  14. If Naval Academy research is right or close..then as we go thru winter the IO convection should intensify as it moves into the MC Sent from my SM-S767VL using Tapatalk
  15. Jeff should love that lol...that's what lead to his 70s in Chatty last Feb Sent from my SM-S767VL using Tapatalk
  16. Some of the research from the Naval Academy Oceanography Division over the last year or so supports your idea Jax. A long way to go in this area of research, but the initial data when going back to 1980 has started showing a correlation between the QBO (when broken into 4 catergories) has a direct effect on how the MJO behaves when it starts entering the MC until it exits. We are currently moving from QBOWL into QBOEM. If the data holds up, QBOEM has shown a correlation to enhancing the MJO as it rotates thru the MC (current theory revolves around the cold/warm pool and shear between the lower and mid trop). Will be interesting to see how the models trend vs the data correlation. Current QBO phase using the 4 phase...and Naval Academy findings presented at the AMS Con.

  17. To me it's more of a intraseasonal pattern shift, the question is when it shifts how much does the enso state/mjo/teleconnections dull or intensify the warm effects...same as when it shifts back. Sent from my SM-S767VL using Tapatalk
  18. Think for next weeks system to work (mainly only for NE TN), would need a really amped system to come NE out of the gulf tracking through the Carolinas, plus the west based NAO to go as modeled (without the Pacific, -NAO is not much help to the rest of us especially the further west you go). The pacific looks horrid, lots of pacific air flooding in with those teleconnections out that way. Great writeup.
  19. I'm just glad to see the Euro not taking such a big poo on the EPO starting around D6 as we keep moving forward. GFS is too all over the place past that point with it's super tanking the 6z. Sent from my SM-S767VL using Tapatalk
  20. All things considering..pretty happy (anytime can get snow in early December is a good time). Even with the delayed precip and melting of several bands..still have around a 1/2" on the ground here. Congrats to everyone who got snow, and hope the Nashville folks get theirs this season (dry slotting was brutal to watch with this one out their way). Sent from my SM-S767VL using Tapatalk
  21. I can't remember the posters name from a long time ago on the older boards, but he had a wealth of knowledge and stats (similar to John here) for the Atlanta area. One thing I will always remember with discussions with him, SD, Robert, and a couple others..was the large majority of snowstorms in Atlanta history involved the MJO going into the COD.

  22. Went for a ride across the county (Monroe)...pouring snow central and northern end with some sticking beginning to happen on the centerline of Hwy 68 between Madisonville and Tellico Sent from my SM-S767VL using Tapatalk
  23. Very interesting system, especially where the training (lack of better word) setup. For whatever reason, we never could get much going along the spine of the mountains here (across Polk/Monroe/Blount) Sent from my SM-S767VL using Tapatalk
  24. Yeah, very nice band about to move over you. 30-40 dbz showing up.Sent from my SM-S767VL using Tapatalk
  25. Backside really squeezing everything out tho..rates intensifying as it approaches Sent from my SM-S767VL using Tapatalk
