I have the pleasure, if you like, of being able to see the Met Office from my office desk. Its a largish modern building with a somewhat sloping flat roof. On several occassion you can see at least two men on the roof picking up and holding what may be sea weed...........
On the other hand, dont they say that 'a weather foreacast is just a horoscope with numbers and inaccurate numbers at that!'
