does most precipitation from clouds start out as ice crystals?
When the ratio of ice crystals to water droplets in clouds is on the order of 1:100,000, conditions are right for precipitation to begin. When there are too few ice crystals, the existing crystals grow large and fall out of the cloud, leaving it unaffected.When there are too many crystals, a cloud of ice crystals is formed, and no precipitation occurs because the individual crystals are all too small to fall to the ground.Cloud seeding is an important process used quite often in the winter to create precipitation.s we have seen, when precipitation first begins to fall it is usually in a frozen state. Often precipitation begins in the form of either graupelor snowflakes. Snowflakes are an aggregation of ice crystals. Much precipitation falling at middle latitudes, even in mid-summer, falls as snow flakes in the beginning.
