Thanks David, superb links to IPV information.
The 400K T+72 from ECMWF looks really weird, not what I would expect to see. Are
there any dynamical climatologists looking in here who would care to comment on
the present situation ?

Will.

polar vortex seems to have shifted quite a bit from it's climatological
position...
BTW I was having a look at this as well and came across this page with
extensive polar vortex data
and diagnostics-
