Question

1.      How far would a polar stratospheric cloud particle fall during winter (100 days)? Assume the particulate diameter is 1 um, and that the settling or terminal velocity is approximated in figure 8-8. Would this be enough for a mid-stratospheric particulate to reach the tropopause?<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

km of mid stratospheric attitude is 30 km

<?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" />terminal velocity is 10^-4 cm/sec

Tropopause height is 12 km

Explanation / Answer

distance travelled by the drop in 100 days = v*t

= 10^-4*10^-5*100*24*60*60

= 0.00864 km

So, the particle wouldn't reach tropopause.
