Does anybody have an advection routine out there, so that I can
say
(x_new,y_new)=advect(u,v,x,y,timestep) ???
Otherwise I'll have to write one but *surely* someone has one... but
google couldn't find one for me.

Hi WIlliam,
Googling IDL advection returns a swag of hits, including :-
http://www.atm.ch.cam.ac.uk/acmsu/newsletter14/group_others. html
which advertises "The tracking of aged air using 3-D trajectories
(IDL code to do 3-D advection is available if anyone's interested)"
But apart from that, I need to make the observation of how small this
world is. This morning, whilst reading the weather page in the local
paper, the "Did you know" column described different types of fogs,
and there for the first time in my life, I saw the word "advection."
Now, 90 minutes later at work, the top posting in the Google IDL group also
mentions "advection."
I'm sure David F. would have something to say about degrees of
separation. I'll stick to spooky...
