Figure 3.5. This figure is the same as Fig. 3.3, \.;rith the addition of
some possible ice crystal trajectories (dashed lines \.;r1.th
arrmvs). The farthc~~t dO\Vflwincl (farthest. right) trajectory
shows the fnll of a crystal with a terminal velocity of
1. m/ ~;t~C. All other traj ectorics originate as 10 111ll Pla
crYf,tal~; and Grow and fall accord ing to the equations of
Davis (1974).
