You are right, the machine isn't compensated for altitiude (wife's Christmas
present I just brought back from the Far East last week!) - I think the
readings should be increased by about 3.5millibars. Still an unusual ROC,
especially for this part of the world.

Hi Ian
The rise in pressure was of the same magnitude here.
But more stunning was the 10mb rise in one hour between 7am and 8am.
I presume your barometer isn't calibrated to compensate for altitude?
as 960mb seems a very low reading.
Alex.

Dunkeld, Perthshire.
At 06:00 we had 960 mB here, less than 5 hours later we had 981 mB. For
this
part of the world (where a little local flooding represents extreme
weather)
this was a fairly deep hole in the sky.
