Zusammenfassung |
Persistent contrails and natural cirrus clouds often coexist in the
upper troposphere and contrails can be embedded within cirrus
clouds. The present paper deals with some questions regarding the
interaction of cirrus clouds and embedded contrails. I have selected
only questions that can be answered by analytical means. I find that
(1) the emission index for water vapour is only slightly changed
when an aircraft crosses a cirrus cloud, (2) that contrail formation
is not affected by an ambient cirrus, (3) that cirrus ice crystals
entrained into the trailing wing tip vortex do not efficiently
retard the sublimation of contrail ice crystals, and (4) that cirrus
can start to dissolve an embedded contrail after a couple of hours
by aggregation. |
