Balloon Trajectory Archive
Figures showing the forecast balloon trajectories are listed by the
date that the meteorological forecast was started (the `base
time'). There are eight forecasts corresponding to "balloon launches"
at 0, 16, 24, 40, 48, 64, 72 and 88 hours after the base time. Since
all base times are at 12GMT, these correspond to a balloon launch at
12GMT the same day, at 04GMT the following morning and then 12 and
04GMT for the following three days. The most likely launch time will
be in the early morning.
Note that the balloon flight plan includes the 2 hours taken to
inflate the balloon on the deck of Qinetiq's ship Triton. The ship
will be moving with the wind to prevent the balloon being blown
over. The forecast balloon releases occur immediately after inflation
(at 14 and 06GMT).
