Previously, we discussed in this chapter about evaporation and condensation in the atmosphere. However, water vapor needs a solid surface to condensate, such as your cold glass, and most common in the atmosphere, a small particle called cloud condensation nuclei, or CCNs. Our atmosphere is abundant with tiny particles of a size about 0.0002mm such as sea salt, pollen, dust, and volcanic ash. Figure 21 compares different cloud droplets with the CCNs.
