Does anyone here know why, when an area of rain is projected to move

the country on BBC TV presentations, it does so rather like a worm? (The
leading edge moves on leaving the trailing edge in place, then the
trailing
edge catches up while the leading edge is stopped.)

I would have expected it to be more difficult to program this effect than
the more realistic whole-body translation.


Morphing between 3-hourly time-steps?

Must admit after a period of months with these graphics, I still don't
like them. At least they do occasionally introduce isobars and fronts
for the dozen or so of us that they obviously think understand them!
Don't they realise they teach this stuff in Schools?
