One thing about Dartmoor, Graham has pointed out that gale frequency has
dropped right off and it is possible that the decrease in wind speed has
decreased the orographic enhancement (which is where we get a lot of our
rain). So it is perfectly possible for rainfall to decrease or stay the
same on high ground and increase on the coast, especially in winter!
Have winds speeds decreased in Plymouth like Penzance?


Hi Len, again!

Having just read Jim's excellent response and queries in this thread, I'm
getting interested now in my own hypothesis which I'd dearly like to test.
If I gave you a list of "orographic enhancement days" (moist SW'ly winds),
would you be able to extract the Plymouth rainfall (and wind) data for me?
If we do this well it could end up as a super paper? What do you think?
Could be a lot of work for me initially though to find the days, but that's
science - hard work.

1)Regarding dropbox, I don't think you have to sign up to get the files.
I might be wrong.
You will get a window appearing inviting you to sign up, but if you wait a few seconds the file should appear anyway.

I will email you the file nevertheless Will.

2) Sadly Will, I do not have any wind data for Plymouth.
Historical wind datasets are extremely difficult to get hold of for any station. They are often not hourly measurements, and are of questionable use if not hourly.

The DWRs of course have some wind information up to 1980.
