I have a ws1600 rain gauge, which is a small oblong plastic affair
about 7cms tall and perhaps 10cm long and I assume is of the tipping
bucket design. Mine only registers every 0.5mm of rain, but I have
noticed that in certain heavy downpours the base station increases by
1.0mm almost instantly.

I have not inspected the inside of the unit as it is screwed onto a
large piece of wood to keep it stable, but my current theory is that
the force of tipping in heavy rain causes the 'bucket' to bounce
enough to send it back to its original condition - thus registering
two tips instead of one.


That could be it. I've been reasonably impressed with correlations with
other readings, but heavy rain seems to record 1mm at a time rather than the
spec 0.5mm.
