The small percentage of total debris accounted for by the
observing network is somewhat puzzling. Although it must be assumed
thet a large fraction of the active debris was deposited in the
vicinity of the test site, it is also true that the shortcomings
ef the gummed film technique, which have been discussed in previous
reports, may be responsible for the effect noted.

METEOROLOGICAL INTERPRETATION
The total fallout from the Bravo test (Figures 3.3 and 3.h)
Clearly show the tendency for the major activity to remain near
the source latitude,
tnere seems to be no evidence that debris was carried
northward around the western side of thea Pacific high-pressure cell.
Almost no fallout occurred in Japan, and very little on Iwo Jima
from the Bravo test,
The difference
between the two tests is a result of the seasonal difference in
the location and intensity of the western cell of the Pacific high.
This cell is almost non-existent, in the mean, during the winter and
