Default Measured and "Useable" rainfall

The Drought in the East Midlands continues. Todays low brought *barely
1mm to NW Cambs. Rainfall since Mid August has been less than 20mm and
for the year just 205mm.

My point is, of the 205 mm most has come in 1-5mm showers which have
evaporated before then ever reach plant roots. Is it worth a different
measuring system for rain which actually reached plant roots and
promotes growth.

Of the 205mm, less than 100mm has come in bursts of greater than 10mm,
which *i would suggest is a "useful rain event"

Ned-havent i seen you inthe BFF??
Yep this autumn is amazing for lack of rainfall-im in Rutland.Weve had
the bare minimum we needed to get crops going and just 1mm today.
As for your new measring system-it would probably depend on the soil
and ground conditions at the time.7 mm falling on wet ground would be
very different than 7mm falling on dry ground.I know where you are
coming from.
Have you seen the long term Gfs-high pressure as far ahead as it can
see.Amazing?
