Rainfall radar limitations 30/07/17 (S Hants)
Thanks for that, it's useful to have corroboration of my
observations... and St. Denys is 6 miles NW of here so it wasn't a
very small local effect. Both events being completely missed by the
rainfall radar is in my experience here very unusual, unique in my
experience even in torrential rainfall. The 18 July event was similar
but the divergence seems to have been much less extreme in scale.
I wonder if others have experienced this kind of anomaly?
I've noticed recently that GFS/0.25deg is seriously underpredicting
precipitation rainfall rates, again too small scale events?
20mm/hr for countywide and no hints of more like 50mm or more/hr
