Default Impressive rainfall prediction


"Philip Eden" philipATweatherHYPHENukDOTcom

Having grown up in an era when trying to predict rainfall
amounts even 24 hours ahead was regarded as laughable,
I find these really quite impressive.


Those figures are certainly impressively accurate, but as Tudor Hughes has
pointed out, quite laborious to produce the predications.

Philip. Are you able to explain how you made the calculations and from what
raw data? And presumably the whole thing could in theory be computerised
(automated) so that I could simply call up a location (in my case, almost
exactly 52N 000E/W) and see some predications?

And as Tudor further pointed out, with convective shower rain prediction - a
huge bonus - it is difficult to imagine how any level of accuracy would be
possible. Just as an example, I was out for a walk last Sunday afternoon
and could see a distant shower exactly upwind of me (I was watching the
movement as it got closer - coming directly towards me. Was I going to get
wet?) But by the time it had "reached" me, it had fizzled out completely so
little more than a decayed shower cloud was apparent. Now could anyone
predict with accuracy that I would not get wet? Yes, knowing exact location
of the shower, its expected lifespan, etc, would have worked on the day, but
at T-24? That must remain a dream.
