2016-17 La Nina Watch/Discussion


Tom

Recommended Posts

We're almost playing with a stacked deck for cold all winter if the N PAC sst profiles continue to evolve through October in the way that they have over the last few weeks. After some further reading and investigating, 1978 is my leading analog year. I'm afraid to say that too boldly at this time but it looks pretty legit. Simply put, the Blob is back.

 

Also, my post above from several days ago was supposed to be -.5 in case anyone noticed.

Every long range model is suggesting the NE PAC ridge to build in and hold throughout the month of September.  The anomalies are on fire with +5C waters bubbling up in the NE PAC.  The Blob is back, and its showing some serious strength.

Meanwhile, Nina-like conditions are holding together with a favorable SOI and trades, looks to me like the modiki Nina is not going away.  All ENSO regions are cooling off and expected to continue.  I wonder if we hit -1C for the 3.4/3 regions next month.

The latest CPC weekly ENSO update...cooler waters continue to shift west...no major changes, it appears the continuation of a La Nina still on schedule.  The coolest of subsurface waters still remain in the central Pacific.

The CFSv2 showing the central Pacific warming during the month of September.  I'm not sure what to think of that ATM.

Not much change in the ENSO conditions.  Holding pretty steady.

Central Pacific waters are the coolest and focusing near 150W...

SST Anomalies in ENSO regions 3.4/3/4 have been oscillating back and forth in a clear range.  Wonder if it breaks lower as we head into Autumn.

Edit: The central pacific La Nina is clearly depicted below.  Interestingly, it's placed directly south of the Blob in the N PAC.

Latest NMME forecast...signing the same tune...

Wow Tom. If the cold shows up as indicated, that should be GOLD for the S. Lakes & OHV track. This feels like "that 70's show" in the winter wx dept.  ;)

It looks like it is back to a "Modiki Nina" then?

It's always had a La Niña, but it's not as strong as a few months ago. I find the SCRIPPS model runs a bit cold compared to all the other models.

 

So all this talk of La Nada was never in play? 

 

Couple questions:

1) exactly which zone (3.4, etc) determines the actual "enso state"? Because that graph a few posts back shows Neut conditions for 3.4 during Dec to Mar

2) Which region are those colder La Nina anamolies in? I cant tell from the image(s)

If the SOI continues to stay sky high, the La Nina could very well continue through the Winter months.  I'm not confident enough to say that will happen.

 

ENSO 3.4 region SST anomalies are used to determine the ENSO state.  Here is a map of the various ENSO regions...

Those Scripps colderst waters then are forecasted in the 3.4 region?

Scripps has been super cold with the Niña development since the very beginning. I was kinda in agreement in late spring when we saw the subsurface at -5 and -6°c but now in another string of unusual events this year, I'm pretty much in agreement with the cool neutral group. The cool pool has all but disappeared at the subsurface and the lack of a sustainable atmospheric connection beyond the recent SOI pop suggests maybe -.2 to -.4°c as a maximum sustainable average. There's just really no way it can survive in my opinion.

The CPC has cancelled the La Nina Watch...they are expecting ENSO neutral conditions after all.

Subsurface temps are no where near as cold as they were in the Spring...

The POAMA ENSO data suggesting a weak La Nina throughout Winter...

 

CsyyP8vXgAE2Vpj.jpg

 

As far as typical synoptic patterns go, there's probably not a lot of differences resulting from an ENSO state of weak Nina up to a weak Nino (and all the neutral in between), is there?

I've been reading that there are differences if you are closer to one "weak" ENSO state to the other.  If we do end up -0.4C, or close to a weak La Nina state, I expect more typical Nina conditions to transpire.

I guess I'm not clear on the differences tbh. Do you (we) have maps to illustrate the 2 different outcomes? I think Niko posted La Nada somewhere on here?

No, I don't have any maps to showcase.  However, here is a typical La Nina wx pattern over N.A....one thing that draws my attn is the blocking HP in the NE PAC.  We are seeing above normal SST's in this area which would suggest an even more pronounced ridge to develop, influencing the wx pattern even farther.

 

 

Edit: I just located this map for a weak Nino...

This would technically leave us cold and bone dry, with more like fast moving clippers skirting the area and big storms to be pounding the EC with lots of snows, even as far south into the Carolina's.

Nah, we are not going to see a weak El Nino...Trade Winds are expected to promote Nina-like conditions as we head into October...

It's not hard to find the central pacific cold pool on the map below...I don't recall seeing the central Pacific swing back and forth so much.  Nearly 1C temp swings.
