Finally back online in full force
Just checked my local stats for home and found I'd had 31.5mm to the end of yesterday, which is 89.35 of the LTA for 27 days of July.
19.8mm - or nearly 2/3 - of the total fell across 5 days 4th-8th July... at which time I was on holiday in the Beacons of course!
12.4mm fell across 3 days 17th-19th July, more than half being on the last of those days when sporadic thunderstorms tracked across the area. I must say, I don't trust the measurements for that night much - there was a lot of turbulence going on, and the radar showed rain rates of 16-64mm/hr + occurring frequently across the space of a couple of hours!
The other day I watched a program about 'Cloud Lab', and among the various measurements conducted was one of typical droplet sizes in a polluted cloud as opposed to a clean one.
It turns out that the polluted cloud typically has smaller droplets.
With pollutant levels in the UK's atmosphere having fallen a fair bit during my lifetime, it seems there is now a strong scientific explanation for something that I've long believed to have occured based on experiences at the surface - an increase in typical droplet size over the past decade or so.
I wonder if the recorded frequency of drizzle in urban areas has fallen notably over the past 2-3 decades? If I had the time...
