ever, I think there is practical justification for knowing how
faut the material will diffuse in the stratosphere because if
we are considering ~— a lot of the argusent yesterday morning
centered around whether the material did diffuse rapidly in the
atratosphere or vhether we could consider 1% as trapped there.
This would be a direct measurement of whether this was true.
Now for the looal fallout, I agree, we're mot sc concerned
with £t because it is the lower diffusion thet we're interested
in for the lecal proble.

I haven't finished my statement yet. Well, I mean, if I were
given such a problem the firat thing I'd look for, and it is
an airbursat, I'd look for a rainfall map and see if there's
any ecinoidence of high rainfall vith high courts, and if
there were, I'd be exceedingly pussled, beceuse this is not
supposed to be particulate matter brought down.
And then I'd
aay, well, this shows that this Lengenir collection theory
does not apply to this problem.
I'd ask myself "Well, viet
else could bring it dow if there's a conjunction betvem
high counts and high rainfall?" dnd then I would lock inte
thie air entraiment tusiness, that is, air getting entreined
in the rain.
I don't know of any other mechaniss that wuld
do that; that is, as far as frontal precipitation is
concemed.
As far as convective thuaderstorn precipitation
ie concerned, it might be this terrific turnover along the
lines that we discussed yesterdsy.
But, it apparently takes
