thanks you Will. After reading and learning from these, I doubt you will be as willing to draw such strong links to SSW's and especially to very weak ones, ("stratwarm" is a term used nowhere in the article, or the blog). I could be wrong on that, of course.


In the 1st link that Will provided by the Met Office:

The new model, dubbed the "high top" system, is different from the previous system as it takes into account something known as sudden stratospheric warming's (SSWs) - which have previously been shown to be responsible for cold conditions at ground level.

SSWs happen when the usual westerly winds in the stratosphere, between 10km and 50km up, break down and ultimately reverse.

Maybe dear pupil you should read the detail before lecturing & trying to offer the teacher advice.
