As the data we all want to see is from MO observing sites (i.e. the official ones) should we not expect the MO to release this as part of their public service? (does anyone remember 'public service' :) ). Yes, I know people have been asking this for hundreds of years....... I feel that they should be pressurised, sorry - encouraged - to do this - and put past climatological data on their website from 1994 onwards (to keep the old MWR going) - as a gesture ahead of the COP26 Summit in Glasgow this November. I've tried to get on with the WOW site but it drives me mad.
I agree with all of that. I can't remember when I last looked at WOW.
I've found the EA very helpful in supplying me with rainfall data, at many sites across Cornwall, for recent decades (for free), I might have been lucky getting to the right people! In fact, drifting to another topic rather, several of the sites they gave me data for had been running >30 years, so I was able to draw up this, which I thought interesting.
Because of the significance of convergence along the spine (both sea breeze & frictional causes), if you didn't know about orographic rainfall you'd be pushed to spot it. Proximity to the spine is what stands out. South coast bays (like Penzance & Falmouth) are wetter than the top of the Lizard plateau for instance. Also the well worn phrase 'cloud breaks to the lee of high ground' isn't the dominant factor in Cornwall, even though forecasters love it. The sunniest parts of Cornwall are the north coast & the Lands End peninsula, due in some part to the lack of land based Cu development with a prevailing SW-W wind.
