What I'm interested in knowing is how long it'd take till the
pertubation had grown enough to change the timing and strength of
particular fronts appreciably. If the atmosphere really is a chaotic system
(isn't it?) won't a small perturbation grow?

No, it might grow or it may not, and it will be difficult to find out.

Unfortunately
we can't compare a nuked atmosphere to an unnuked experimentally, so it's
got to be done by computer which is poor, but all we've got. Any ideas
where to find references?

I do not know whether anyone have tried to simulate the effects Anyone?


Timescales:
Within the local area a few hundred km: A few hours
Europe: A couple of days.
Northern or Southern temperate regions: A week
Tropic areas: A month.
The hemisphe 2-3 months
Globe: 1-2 years.

That's about the timescales I presumed for the pertubation to grow enough to
scramble fronts. Is that how I'm supposed to read the table?

More or less.

If I were to give a guess on how your sphere would affect the weather I
would say that you could have some nasty winds and possibly intense
precipitation, locally 100 km away. A front very close might be affected,
but no guarantee. At mid-latitudes I would say that the strongest possible
imaginable effect on a longer timescale would be "removing or setting"
up a blocking high. In other words you would get a wet summer instead of a dry or
vice versa. I do not think it would be very likely however.
