and that is because of the way they cut through the clouds.
If we could have the first slide, I could remind you of the way
the atzoszphere is shaped, and the way 6 cloud moving in the
atmosphere is shaped.
This is a slide prepared by Jim fdinger,
and those of you who were here the first afterncen sar the slide.
It shows a sketch--and this ie a fanciful sketeh, but it is
based on the way one would expect the atmosphere to behave-—showing the eleud at the end of, roughly, ene day, and taking
twe cases: one a rather unrealiatic case in whieh there is no
shear and in wiich the cloud simply spreads through to the action
of gross turbulence and fine-scale turbulence together and, as
Jim pointed out (we won't so through the arguments again), you
would not expect it te be homogeneously distributed; it would
be polled spart and would present wiespa and hot spete and gaps
and patterns.
‘Then the argument went on to indicate that
actually we almost invariably would have shears, and so the
eloud, instead ef being in a pancake section of the atmosphere,
would actually be spread ont in a long belt.
The dimensions
here are conservative for one day; they actually would, in
mest cases I think, be even larger than this, and this dram
to scale.
This is actually a scale drawing ef suck a cloud at
the end of ons day; as I said, these horisontal spreads are
conservative.

This shows it, as one would expect it to be,
Wow, in the case of low diffasion—and there
was some argument yesterday to indicate that the 4\ffusion
