... in major forecasting centres (such as Exeter), they will overlay water
vapour imagery in particular against other imagery and model fields -
modern NWP suites can produce 'pseudo WV' fields - and such errors are
quickly picked out and can be allowed for.


However we seem to be poorly off for real-time WV imagery - I can't find a
loop of such - does anyone know of a source?

click on the region of interest to access the loop

I'll endeavour to provide a pseudo water vapour example that Martin
mentions.

Thanks for that link Jon. That is excellent.

One question that puzzles me, and concerns the contrast on the IR
frames. North Africa looks very dark (due to the high temperatures
there), but the cloud contrast does not seem to show the thick cloud
associated with ex-Bill as particularly white. Could this be my
laptop, or are the cloud tops relatively warm? Or is it just that the
really bright white shade is reserved for the added coastlines?
