Possible strong/super El Niño forming?


snowman19

Recommended Posts

I can't wait to see the Nino just completely dominate the pattern soon the shear force of a super El Niño dominating is really awe inspiring. It's a beautiful thing!

Now to me that denoted a not so cold /snowy winter. As you responded to us discussing the EPO region for the winter.

If that wasn't or has not been your intention then I am wrong , but if anyone wants to go back and your tone/postings since day 1 maybe others will see what I thought I saw.

I never said that I was a fan of snow.....I just root for modokis and negative EPOs.

the pattern right now is great and if it was winter we would be shoveling 14" of snow....

UNC having the negative that far west usually spikes the PNA and combined that with shorter wavelengths possibly developing under blocks , the bigger solution are always on the table .

The scary thing for me is , the seasonal set up looks too good .

At some point a fly may show up.

Maybe it's a just a function of living on the coast at 40N , seeing forecasts ripped away inside 12 hours so one should take a lot of this with a grain if salt.

But as it stands the entire set up is there , it doesn't mean it has to produce , but there are some big players on the field right now.

Better to have them , then not.

Well, it looks like the CFS is finally waking up and starting to go with a December peak for this Nino, just like every single other model has had for months. The CFS was the lone model showing a November peak and it has finally folded to the other guidance, no surprise there

it all depends on how much cold air is available in a set up like this...it could be a mixster or true blizzard...October 2009 had a few days with cold rain in the city and snow in the suburbs mid month...2002 had two nights with sleet and snow at the end of the month...1982 had a noreaster near then end of the month...all had a blizzard in February....I'm not saying that will happen but it is another good sign...the next sign could be a detour so caution is advisable...

Thanks for that - I forgot what the peak was in 97. Still a far way from that, but impressive nonetheless. I'm interested to see the weekly numbers... Tropicaltidbits shows big warming in the past 2 days, but I dunno if it's real because it's been too cool for a long time.

Its precipitation portion of the forecast continues to indicate the congregation of strongest tropical convective forcing around 170-180W, which if correct, would be favorable. This coincides well with its corresponding 500mb map which depicts the sprawling / expansive GOA vortex and concomitant W Canadian ridge immediately downstream. It's probably a mean EPO near neutral for DJF. Of course, we're still far out - so caution should be exercised. It is good to see the maintenance of its prior run's solution, however.

Whether a neutral EPO or slightly NEG. (Pressures are higher both N and S of the GOA negative) so it's a wash. ,What's more important is can those AN SST south of Aleutians combined with the D/L forcing help pull the NEG far enough SW .

If it can then look at those heights on the the west shores of HB, that pos PNA in turn allows HP to slip through the lakes.

I haven 't looked at the 2M temp map but I assume you will AN through Alaska and western Canada and BN Temps in the SE , MA and probably S New England.

Looks like the ERSSTv4 has been running about 0.4-0.6c cooler than the OISSTv2 dataset over the past few months. The new JAS trimonthly will come in around 1.5c, at the threshold for strong el nino.

 

Given the differences, we'd likely need a monthly OISSTv2 value of +2.4/2.5c or greater in order to achieve a +2.0c monthly anomaly on ERSSTv4.

September 30mb QBO value has risen to +12.07, solidly westerly. Will be another factor to monitor for the ensuing winter. Very high likelihood that the QBO will average positive for DJFM.

What are the implications of this?

I know that weak-west is favorable, but it may be more moderate this season.

Don`t sweat the QBO .

 

Compliments of Analog away ...

 

 

2002-03 was a VERY positive QBO. 

 

So was 2004-05.

2010-11 was a bit positive.

2001-02 was VERY negative and that didn't work out so well.

2011-12 was slightly negative.

I agree. There's a lot of variability in winters with negative or positive QBO states to suggest that the QBO likely has only limited explanatory power. Arguably, perhaps the strongest link is idea that an easterly QBO increases the likelihood major stratospheric warming events. However, even such events are not sufficiently well understood for high confidence predictability. Last winter was another case that illustrates such limitations. The strongest stratospheric warming event was a moderate one despite an easterly QBO and despite some of the guidance occasionally hinting at stronger events that would weaken or split the polar vortex.

 

I could be wrong, but IMO, if the other "players" are in place, we should have a decent winter. If not, we won't. The QBO might contribute a little, but it won't make or break the upcoming winter.

here is a link to the QBO numbers

not to argue at all, but I wouldn't agree with some of your characterizations though would agree that the QBO shouldn't hurt us unless a rising +QBO is a problem

I mention that only because of the 01/02 debacle

http://www.cpc.ncep.noaa.gov/data/indices/qbo.u30.index

 

p.s. 13/14 was positive and that turned out pretty good for most in the MA and NE

Looks like he was looking at 01/02  

and not 02/03

02/03- D-M 0.20 0.04 -0.04 -0.25 = Neut .

 

Yep , 2014 J - M 1.23 1.12 0.98

One could only hope ( I do ) that there is a 500 mb link between OCT and J -M 

 

 

There was with the top five strongest Nino's on record where the October pattern continued into winter with those five.

Numerous others in the top eleven strongest El Nino's like 09-10 also followed suit. But there were also a couple that

didn't follow the pattern. The weak events like last year and 77-78 didn't show the carryover from

October to winter.
