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

Does it really matter? They don't even know when to come in out othe
rain themselves most of them. They seem to tend towards the Blue Peter
& Play School end of the presenter's spectrum these days.

Whoever or whatever is in charge of the transition must be doing it for
the sake of making cuts. I'm not even sure they are financial ones.

Hopefully if that is so, a flux of meteorologists released from serious
positions may be answering ads for TV presenters in the JobCentres
around places like Birmingham soon. Some financial whizz kid of Aunty
B, might see an opportunity there.

Maybe in decades to come any chosen might serve to redress the balance.
Maybe the independent channels will see an opening and usurp the Beeb.

Don't hold your breath.

Time they did. There's no substitute for a proper broadcast by an
experienced meteorologist despite the tools available to us on the internet.
Could TWC again launch a version for the UK/Europe? The last time they tried
was around ten years ago and we now have (cheaper) digital TV and much
greater resources to make it interesting. A global look is required as there
would not be enough of interest in the UK for much of the time.

Hard to believe BBC presenters want to continue with the present graphics.
It must be very frustrating for them.

Yes, that's right Norman. I asked a BBC forecaster why fronts kept splitting
as they crossed the UK and that was the answer. A case of the using the wrong
interpolation algorithm.

How many times do I have to defend geography teachers in this country?

As I have said on this forum so many times, yes we do teach synoptic
charts, pressure patters, fronts, isobars, even basic forecasting at
age eleven! By the time we reach the 6th form, we teach about general
circulation of the atmosphere, Rosby waves, climate change sice 1300ybp
and much more.

Why does society blame teachers for everything?

Why don't they use the hourly data from the model?

Hi Steve,

I was defending teachers, I know from my own teenagers that they teach a
lot more about the subject than I was taught 30 years ago, not sure
whether that came across in my comment :-)

Sorry Keith, got hold of the wrong end of the stick - doesn't hurt to
plug the profession though, especially Geography teachers:-)
