TT-SEA Posted May 25, 2018 Report Share Posted May 25, 2018 Subtropical storm Alberto has formed. FWIW, previous Mays (non-noñ) w/ names Atlantic storms/-QBO50 are: 195419591970200720122016 And 1959/1970 are the only solar maximum years. Seems like a solar minimum tendency.You ruthlessly mocked the GFS for showing this 10 days ago.

Anticyclones will be retrograding quickly enough to keep the ridgy spikes short (~ 2-3 days to complete each cycle).

Phil Posted May 25, 2018 Report Share Posted May 25, 2018 We have intraseasonal forcing propagating into the EHEM/Indo-Pacific now. This is the reason for the upcoming troughing/-PNA and temporary demise of the Baffin Bay vortex. Once convection reaches the middle of Phase-7 (WPAC) in about 20 days, the pattern will begin to change again, with strong ridging returning a week afterwards (week-4, in this case). The more amplified this intraseasonal forcing gets, the slower it will propagate. A less amplified wave will propagate faster, but it will have less punch. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

Phil Posted May 25, 2018 Report Share Posted May 25, 2018 And when it comes to EHEM forcing, the CMC and UKMET are often the best at handling it. The ECMWF is great with WPAC forcing, and the GFS is best with EPAC/WHEM forcing.

Phil Posted May 25, 2018 Report Share Posted May 25, 2018 We should start a countdown clock for when the troughy period ends.Pick your poison. Stronger troughing/EHEM forcing now = stronger ridging/WHEM forcing starting in weeks 4/5 and a slower cycle back to EHEM forcing. Weaker troughing/EHEM forcing now = weaker ridging/WHEM forcing starting week 3/4, which will cycle back to the EHEM faster.

Phil Posted May 25, 2018 Report Share Posted May 25, 2018 The structure of this wave does suggest it might be a higher frequency affair, and the SST gradients across the tropical Pacific are weak enough that a weaker/faster MJO/CCKW wave is probably favored. But we’ve seen these things amplify before, especially with the raised tropopause/-QBO downwelling as we speak. So I don’t know which outcome to expect yet. But it will be fascinating to watch.

We need some deep troughing and decent rain to help prevent another bone dry summer and bad wildfire season.

Phil Posted May 25, 2018 Report Share Posted May 25, 2018 Though even with a faster/weaker wave, the GFS projection of VP200 anomalies is almost certainly too fast/weak. Which makes sense, given its WHEM forcing bias. Notice how it tries to throw convection eastward at a rate that is much faster than the current propagation rate. http://www.atmos.albany.edu/student/ventrice/real_time/timeLon/vp.anom.30.5S-5N.gif Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...
Phil Posted May 25, 2018 Report Share Posted May 25, 2018 So in this case, I would favor the GEPS (CMC ensembles) over the GEFS. Note how the GEFS bifurcates this MJO/CCKW during week2, leaving residual uplift in the IO while propagating the rest of the wave into the WPAC/WHEM, voiding the Indo-Pacific. This is unlikely to occur. The GEPS, on the other hand, maintains the wave-1 regime, propagating the convection into the Indo-Pacific. This has more historical precedent. And while these differences appear subtle, they are very consequential as far as mid-latitude wave cycles are concerned.

Especially with a hot July-September looking imminent.July looks like a roast (or at least the first 3 weeks of the month do) but the lower level -QBO/z-cell retraction should be far-enough along by August to prevent a torch, not to mention the favorably-timed intraseasonal tropical forcing by that time. If the -AMM/-AMO cell holds, then there’s a chance for a legitimately cool August and/or September this year. If the +AMM/+AMO cell returns (which would mean a return to the 1996-2017 ITCZ seasonality) then a cool August is less likely. In fact, even 2015 (super-niño) entered into a zonalish, equatorward z-cell regime in Aug/Sep as the -QBO downwelled to the tropopause. And 2016 (the skipped QBO cycle w/ anomalous easterlies @ 50mb emulating another QBO downwell) also flipped cool/zonal in late August/September. Around the same time as 2015. This isn’t a repeat of 2017 or 2014 (downwelling easterlies above westerly shear).

Phil Posted May 25, 2018 Report Share Posted May 25, 2018 FWIW, it looks like both April and May will finish with +SOIs. In the 1950-present era, yoj have to go back to 1963 to find an example of a niño that developed with +SOI values in both April and May. However, 1968 is an oddball, as it doesn’t meet the specific criteria, but it had tons of +SOI during the summer. A weird year..strong niño in the heart of a -PNA/-NAO decadal cycle, along with a cooling globe at the time. Though, if you count 2014/15 as a niño (debatable) then it meets the criteria too. However, it was a very borderline case in a solar maximum/eastward cycling IPWP regime. Either way, the point stands. Very unlikely to see a niño when both April and May run +SOI averages.

Phil Posted May 25, 2018 Report Share Posted May 25, 2018 In fact, given March 2018 was also +SOI, that eliminates 2014/15 from contention. The only year in the post/WWII era to develop a niño with a +SOI in March, April, and May was 1963/64. And you could lump 1968/69 in there, even though it doesn’t fit the specific criteria (summer was strongly +SOI, even though spring wasn’t). And the circulation today is NOTHING like that of the 1960s. That was the heart of the -NAM era. So IMO, you’d better have a good reason to bet on a niño this year.

Front Ranger Posted May 25, 2018 Report Share Posted May 25, 2018 No... but the first 2/3rds of April was sure wet. I said at the time that a dry spell was VERY likely coming for my area which usually means dry for everyone. It was an idea that was dismissed at the time. Two wet weeks, surrounded by drier than normal weather for weeks on end. Looking back now, the whining becomes even more ridiculous in hindsight. Quote A forum for the end of the world.
