Title: Describe cloud formation and resulting weather.
Course: Aircraft Pilot Training II (20053-II) > Section: Examining Atmospheric and Meteorological Conditions

Description should include the following:

- Clouds are visible indicators and are often indicative of future weather.
- For clouds to form, there must be adequate water vapor and condensation nuclei, as well as a method by which the air can be cooled.
- When the air cools and reaches its saturation point, the invisible water vapor changes into a visible state.
- Through the processes of deposition (also referred to as sublimation) and condensation, moisture condenses or sublimates onto miniscule particles of matter, like dust, salt, and smoke, known as condensation nuclei.
- The nuclei are important because they provide a means for the moisture to change from one state to another.
- Cloud type is determined by its height, shape, and characteristics. They are classified according to the height of their bases as low, middle, or high clouds, as well as clouds with vertical development.
