OK thanks. I saw this and was a bit concerned.

I bet this signal mutes some in phase late 4 - 6, as you see it plotted in that Wheeler curve...

 

It was robust ... ah, 'er' when it was first progged to go through phases 2-3-early 4, and it kept correcting toward a muted signal.

 

The reason why is that same thing I've been hammering for years about the hemisphere's other teleconnectors, land, air and sea (so to speak..) being in constructive vs deconstructive interferences wrt to each individual correlated section of the chart. 

 

The warm phases for us, the 3-mid 6s are typically of a neutral PNAP to -PNAP pattern bias, that tends to cool the west and warm the east.  The opposite of course being true for late 6 - 1 or 2...  

 

During an El Nino, a +PNA is correlated better.  That would tend to mean a +PNAP, and ridge in the west and a trough in the east.  

 

Doing the "pattern math" that tends to cancel out - i.e., 'deconstructive wave interference'

 

I suggest that is why the 50,000 foot appeal of the last 30 days of Wheeler shows robust wave strength on the other side of the diagram, while the wave appears mooshed toward the rim of incoherence on present side; it's because the wave is having trouble maintaining cohesion in a hostile environment.  

 

What all this really means ( for me ) in more practical terms, the MJO's ability to modulate the pattern is a bit handicapped do to the fact that those right side of wheeler phase spaces are opposing the atmospheric/hemispheric longer term signals.

Ray is making the thread as I type this.

 

He's already locked in at least a MECS....just a question of whether we all get 20"+.

 

 

 

 

In all seriousness, it's a nice signal and even if nothing happens there, the pattern looks really strong after that....looks like it would sustain pretty easily beyond the end of the run.

Temps in the 11-15 day look a little AN over NE and the east coast on the EC ensembles. Perhaps an inland track?.

 

 

We're close to the baroclinic zone D11-12...gets pretty cold after that though. I'm assuming that is what it is trying to display.

 

 

But.. I mean -12C at 850mb on a D14 ensemble is pretty strong for a cold signal. So not sure where it's finding the warmth to offset it. It's not like D11-12 are actually furnaces. Perhaps the sfc isn't showing what 850 shows.

It's a little west. Not quite as far east as last February...of course, we're talking the mean longwave look at D10-15, so take it FWIW.

 

Sounds perfect.  An axis over like the eastern Lakes is probably best anyway....also if it gets cold with like -20C to -30C H85 sitting north of like Toronto, maybe we can get that PV sucked into Ray's huge east coast storm this month.

 

Edit:  Just saw them and yeah that's what I'm looking for, ha.  Wow.  Keeps H85 temps near normal right on the coastline, with best negative anomalies over the Lakes.  Baroclinic zone must be right on the coastline in that one.

:lol: I'm an idiot. I already looked at that page and thought it only went to day 10. I was just looking through the meteograms and stuff to find the day 10-15.

Thx dude.

lots of spread at this range but as Scooter and Will said sign me up for that look. Notice how DIT didn't say they went wild, met kiss arse
