1、The vertical distribution of cloud droplet spectra has three typical sorts.
2、In fact, the tiny cloud droplets do sink, but so slowly that it would take an hour for a single droplet to sink only one yard.
3、The falling speed of cloud droplets is small and falling cloud droplets are not very effective in scavenging smaller particles.
4、It is legitimate to envisage a more or less one-to-one correspondence between cloud nucleus concentration and the concentration of cloud droplets.
