Hello,

As the senior developer on the BBC Weather site, I'd like to point out
that the weather data displayed on the  site is supplied by the Met
Office, and not the BBC.  We have been monitoring the sorts of
discrepencies you mention between the 5day and 24 forecasts, and
feeding them back to the Met Office.  They are keen to improve their
quality control processes in response to this.

Thanks,
Kass

hedging the weather

barcamplondon featured weather averaging for four major suppliers.

I queried the sense of this given the BBC's approach...

for instance today in London the (day) forecast is "light rain shower"
that's half the rays of sun, plus a dark cloud with one rain drop.
already pretty vague you might surmise...

However when you switch to the 24 hour forecast the 3 hourly forecast
throughout the day is "Sunny" throughout the day, with clear morning
and evening.

given the vast expense of weather forecasting, this cannot be said to
qualify as science, it doesn't even pretend to scientism or
scientistic tendencies, more like pure guesswork of a pretty vague
and less than helpful sort?

cheers

Jonathan Chetwynd
