积云内冰晶浓度：液滴谱的影响。

Science. 1974 Nov 15;186(4164):632-4. doi: 10.1126/science.186.4164.632.

Secondary ice crystals are thrown off when supercooled cloud drops are captured and freeze on a moving target in a cloud at -5 degrees C. The rate of production of these ice crystals is proportional to the rate of accretion of drops of the diameter >/=24 micrometers.

当过冷的云滴在-5°C 的云中被捕获并在移动目标上冻结时，会抛出二次冰晶。这些冰晶的生成速度与直径大于等于 24 微米的液滴的积累速度成正比。
