Anyone know anything about this 'Decider' forecasting software
apparently developed by UKMO and which seems to categorise the
forecast period into one of 29 weather 'regimes'?

There's a rather undetailed write-up in the Sunday Times today (quite
separate from the main UKMO story) - see:

Apparently it took £40K to develop. I'm not sure whether or not that's
a misprint but £40K would be a tiny amount for any worthwhile program
development I would have thought - maybe 4-6 months of one
programmer's efforts. I guess it's not software for private
individuals to buy - they would presumably need to subscribe simply to
its ouput. In any event EDF seem to like it.
