Questions and Answers
What is the primary issue with cloud droplets forming precipitation by themselves?
Cloud droplets are extremely tiny and fall in still air incredibly slowly, requiring a growth in volume by 1 million times for precipitation to occur.
What is the role of ice crystals in the Bergeron process?
Ice crystals grow larger at the expense of supercooled droplets, increasing their weight until they fall, and accumulating more cloud droplets through accretion.
How does the Collision-Coalescence process occur in warm clouds?
Larger cloud droplets fall faster, collide with smaller droplets, and merge through coalescence, facilitated by opposite electrical charges and aided by updrafts that allow for more time to grow.
