However, throw a rock into a serene lake and the ripples will propagate for a long distance! The extra water vapor begins to condense out of the air parcel in the form of liquid water droplets and a cloud is formed. Then, if the temperature at the crest of the wave drops to the dew point, moisture in the air may condense to form lenticular clouds. However, cloud types are separated into 10 main categories.
