(3) Frequent post-shot wind forveaste should be made daring
the interval H to H plus 2h hours in order that the actual orientation of

f-ll-cut pattern may be more accurately analysed in conjunction with the post=
sot weather and radsafe cbeervaticas.
(4) The frequency and aceuracy of pre-shot weather forecasts
wore adequate for realistic planning and fall-out forecasting following the

m iification discussed in paragraph la (4) above.
(5)

Continued research and stuty of tropical artecrology is

saquired in order to improve long-range wind forecasts.

(6) The eaployment of constant altitude balloons as a forecasting tool, alttough nct successful on CASTIZE due to operational, supnly
and mechanical difficulties, is still considered a valuable adjunct to the

‘duather/Radeafe forecasting techniques.

(7) Rawinsonde balloons frequently “Leed" and burst at the cold
tropical, tropopause.

As @ consequence, critical wind observations were

scastimes terminated prior to reaching the naximm significant wind levels.

(8) Base to the teniency of the winds to be westerly at points

to the north of ground sero, additional raviasonde sites in the northwest
and northeast quadrants would have been extremely useful.
Ce Pall-out forecasting

| (2) Assumptions:
(a) As a general rule, the aseumptions of 24 hours and 500
nautieal miles as the upper limite wigdin wiich significant fall-out could

oGeur were valid,

Although air eont mination from water surface shots extencs

the tims to approximately 24 to 30 hourw, the sercscl-type clead from such
shots preeluded significant fall-out levels at such lata times.
