[Gwo And Global Angular Momentum]

Could someone tell me what "nbsp" stands for?

And also "MMW", which is being used elsewhere relating to Strat. issues?

Looks like a double whammy from this warming. Not helping Winter; Ruining Spring!

I'm posting this here in response to the discussion regarding this paper http://ams.allenpress.com/archive/1520-046...69-22-6-597.pdf .....in the Model Output Thread.

I personally think that Winter SW warming events are "linked" with cold winters and that recent "bad" winters were ruined by the strong omnipresent PV.

However this paper begins by talking about a mid-Jan 63 warming as contibuting to that phenomenal winter that I remember so well.

However the Autumn of 62 had been mostly very cold and the extreme cold synoptics were in place by Xmas day. By mid-Jan we were 3 weeks into an uninterrupted regime of extreme cold.

If the Warming takes 2 weeks to alter the synoptics, then we had already had 5 uniterupted weeks of record-breaking cold, by the time the "cause" arrived!

Perhaps that winter was caused by other factors.

Or perhaps the SSW is not the direct cause? Could it be a parrallel effect caused by a deeper, unknown, cause that promotes cold NH winters?

Could it be a "marker" rather than a simple cause? Or a self reinforcing "product-&-further-cause" of cold.

Notwithstanding my queries about it "causing" the 62/63 winter I still think it's the best explanation we have for "good" and "bad" winters.

Please keep up the info. GP et al.
