... showing up well on this series from Teesside (EGNV) airport (latest
at top): the third group is the surface wind, and the following group in
the top three are the variations: note the 040V250 of the 0950Z ob; wind
varying from 040 deg (i.e. from NE) to 250 deg (i.e. from WSW)
underneath a theoretical gradient flow of 270deg (or from the west).
Quite tricky for a/c on approach I would have thought- much stronger
winds above 500m or so .. see below.
