I have been having a small amount of success in my project to dynamically create animation GIF
files from still images. I have written a small single MS-DOS batch file which, when run,
automatically downloads images and then creates animations. Have a look and tell me if you find it
useful.

All I need to do now is to set up a scheduled task in Windows to run my batch-file at regular
intervals!
BEWARE. The GFS animation is about 3 MEG ! but I think it looks pretty cool*
I might have to shrink the image size or skip alternate frames or reduce the number of colours to
reduce its size .
Any ideas or suggestions ?

(* "cool" as in a forecast of some cold weather!)

Sounds like you animation prog is simply saving each frame completely
rather than just the changes from the previous one. Any options in
your animation programme along those lines?

That's great!

Any chance of posting the text of the batch file as I have another use for
something like that

Well done Brendan, thank you

Luckily I'm on ADSL so the size doesn't matter - I notice that on the web page
you say it's only 2MB
How about giving people the opportunity to choose a smaller one if they don't
have BB ?

Another thought was as I was looking at the cloud/rainfall - how about a page
with them both on side by side so comparison's easy ?

If there was any simple means of interpolating the hours between the standard
synop hours so that the whole thing could be smoothed - that would be superb.

Nevertheless an excellent animation, showing a small pool of sub-510dam air
"breaking" off the trough and disappearing over SW England. also the
development of the omega block is well shown.

Hi Brendan,

Thanks a lot for that, very useful indeed. I don't think there's any need
to decrease the
image sizes. 3MB, even on a 56K, doesn't take particularly long to
download.

Yes. I noticed that too. The animation reminded me of a lava-lamp, in the way the 510 dam breaks
away.

rather than just the changes from the previous one. Any options in

Yes, I think there are "optimisation" settings. I shall take a look...

Fluid dynamics could be part of that.
