elouds which have Deen aade ” surpgann of the atmosphere,
which show, in fact, that as one goes from the relatively
unstable troposphere where wa have the decrease of temperature
with height, inte the stratosphere where we have roughly lsc-
therual regions, the amoke puffs which grow at a certain rate
in the troposphere, grew even faster in the lower stratosphere.
This was an observation mado on the basis of about 20 sxoke
puffs over Folloman Alr Force fase in the saseer ef 1919.
This
conclusion was rather surpriging, Decanse it was usually assumed
that when you got inte the stable layer the diffasion would be
slower.
Now, whet takes place still further en up Le nor a
matter of conjecture and, as I say, { would be inolined to
agree that the rate of mixing was sicwer in this upper region.
But I really den't think that ws can say that definitely yet.
WEILER:
“LT these meascrenents...do thay actually dstermine a threeainenstonal shapes of the puff before and after?
KELLOGG:
There were three phototheodolites, and it was posaible to
determine the shape.
in effort was made to separate the effect
of shear.
WEXLER s
Was there any indication of nen-isotropical...I mean, was there
any elongation of an axia in certain directions?
FKELLOGGs
Yes, but this almost alwsys in s borisontel
