Chart No. 11 is the computed air particle trajectories for 254%
day, based on data available through 3433 hours.
Acrlification of
trajectory was essentially the same for 30,000 feet.

From 6,000 to 6,000 feet, the trajectories
egein start snowing northerly components, with the 6,000 foot ani delow trajectories being generally froz the ezst northeast.
