... 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.


An example of the pseudo water vapour field that Martin mentioned with 300mb
GPH overlaid for midday today.
