place from the fact that temperatures at the ground drop dow
wall below the levels they're supposed to drop down if the air
stays the same and if the air was ccoled by evaporation and
felling rain. Well, but suppose, en the other hand, you did
not get a coincidence cf the high eounte with the high rains.
Then that wuld eliminate the rain es 8 possitile inpertant
factor and you'd have to lock for other mechanions not con
nected with rain. Well, then I would invoke, first of al),
lange nase movenenta of air vartionlly on isentropic surfaces.
You may not have to go throwh « detatled isentropic enalysis;
you may just mske uae of general metecrologisal considerations
of descending aly connected with anticyalenss and things like
that. In that wy I'd try te interpose possible mechanian,
depenting upon how the data in exch particular onse seas to
agree both metecrologically and redicectively. fo aid in the
interpretation and te aid in putting forth reasonahile mechanisms, I thoroughly agree, Will, that it's just as important
to have vartiosl traverses as horizontal traverses, which
we're now getting. The vertical traverses are necessary, but
I doen't think that they'll ever give the fine detail that is
covered by the wards“the three dimensions) pleture of aloud.”
I think 27 will just be an extra bit of informtion to help us
decide whether it was possible for this cleud - radioactive
aloud ~ to have been caught in the rain area or not, and things
like thet. I don't think it will throw any Light quantitatively
that will improve our understanding of vertical. diffusion.
