Comparing supercooled water and ice, the difference in their saturation vapour pressure reaches a maximum at about -12C. Consequently, the ice crystal process will most effectively produce precipitation at which of the following cloud temperatures?

Question

Quizplus · Accepted Answer

The maximum difference in saturation vapour pressure of supercooled water and ice occurs at around -12°C, which means that at this temperature, the ice crystal process is most effective in producing precipitation. Therefore, the best choice is around -12°F/-24°C, which is option B.
