Seems to be a strengthening of polar jet and a poleward shift.

Thanks for that, Len. Quite a lot to digest there and the
response of surface winds in southern Britain is not obvious. The
northward shift of the jet and the raised tropopause is to be expected
but the strengthening of the jet is not something I would have
foreseen.

On a personal note, I'd say I am now a little better informed on
the subject but this sort of research will have little impact on my
pub mate's views, he being something of a fundamentalist Green who
"knows" that everything will get worse if the temperature goes up (but
not down).
