Air must become saturated enough
Cooling, adding moisture or mixing air masses can bring air toward saturation.
Cloud condensation nuclei matter
Tiny airborne particles provide surfaces on which droplets can form.
Rising air often cools
Expansion at lower pressure can lower an air parcel's temperature.
Cloud type reflects motion and stability
Layered and vertically growing clouds reveal different atmospheric structures.
