Banter for the End of October

If we get an 11-12 redux, not many :whistle:

 

Just a hunch, but I would not worry about a 2011-2012 redux. That winter was such an anomaly that to get that exact same set up again this winter would be remote. IF we have a winter that doesn't satisfy everyone, I would have a hard time believing that it will be to the extend of 2011-2012.

he is

 

notice how less active its been? boring begat boring at least Kevin kept it active. Oh well its what you want, enjoy

is he really? haha. so that's why he's not posting at all.

 

well...maybe the time away will be good for him then. i'm sure when there's a storm coming he'll be here...though i don't think he likes snow as much as he used to, so maybe not.

I would think that makes you hate cold temps more than snow. :lol:

 

Random question but I remember one year I think it was Chuck posted a map showing the which regions of the 500mb anomaly map you use for certain global indices (NAO/AO/PNA/PDO).  I think what he did was use 500mb anomaly map from the reanalysis site from ERSL...what he did was just use paint to write where each region was.

 

Do you happen to remember if that was done on here or over at eastern?  It was fantastic and I've been trying to find it b/c it's a great refresher.

If anyone wants to watch it snow, Jay Peak put up a sweet little vid of the snow falling.  I could watch this all day.

 

Northern Greens from Sugarbush/Mad River Glen northward through Bolton, Stowe, Smuggs, and Jay all got in on the upslope/lake effect action today.  Beautiful flakes, too as these meso-scale things tend to produce with good snow growth and some aggregates. 

 

Meso-scale looks like the only excitement for a while... lake effect and upslope.  Pretty climo for this time of year though with these cold pools moving in on WNW winds.

What makes this such a negative NAO?  

 

Is it b/c the North Atlantic High is much, much weaker than normal?  Trying to locate the PV here as to see whether that would be weaker than normal but is the PV here displaced towards Europe? 

Since the Azores High is experiencing lower than normal heights that lessens the pressure gradient between that and the Icelandic Low which allows that cold air to meander south, hence troughing as well. That's just a quick explanation I'm sure someone could provide more.

Thanks!!

 

I was just intrigued by this look as typically with a -NAO, you see some above-average height anomalies around Greenland and with the more negative NAO's pretty large anomalies.

Yeah I can't say that's a "textbook" -NAO example there but if you look at that plot the area over Greenland is "neutral" (since it's white) so you can still consider that to be a low heights region.

 

As far as the location of the PV, I'm not sure where it is either. My guess would be over Siberia? I really don't know though.
