I don't know what satellite pictures you were looking at, but the
past couple of days of Meteosat pictures show the outflow cloud from
hurricane Gordon being sheared further and further NE towards the

apart from it encountering lower sea temperatures - was the
increasing shear it encountered as an upper trough caught up with
it.


... not sure if this link will work, but it takes you to the
Meteosat site where you can pull up WV imagery and animate same.
Unfortunately there is no ability to enhance the contrast (or
colour-slice) so it's a bit 'wishy-washy', but you can pick out the
high-concentration WV (and solid/liquid state water) being injected
into the upper troposphere from 'Gordon' and then latterly being
picked up and shed NE'wd ahead of the major upper trough progressing
towards the British Isles.

Thanks for that, Martin. I was using the Dundee University pictures and
cycling through by hand. The WV images are at
http://www.sat.dundee.ac.uk/geobrows...&grid=1&size=1
and can be cycled through at 6-hourly steps by clicking the "+" and "-"
buttons. They have the advantage of going back further so that one can
start when Gordon was still a hurricane. They might take a while if
your broadband is a bit narrow but smaller images are available.
