Can anyone tell me if there is an average thickness value for each
month
here in the UK?

Thanks in advance.

.... I was hoping that someone in a big glassy building on the edge of
Dartmoor might pop down to the Library and look these up, but they are
all probably busy saving the Planet ;-)

I don't have access to these data now - but unravelling (?) the various
mean mslp/500/TTHK diffs charts that are published with the R.Met.Soc
'Weather Log', I've worked out some rough figures for the lowest and
highest for two locations ... this is not an exercise I recommend for
the sake of the eyes! Very small charts, small-scale etc. Treat these
figures as a good guide without being gospel (fairly happy with a +/- 1
dam possible error).
