A short course in cloud physics offers a comprehensive introduction to the science of clouds, covering everything from basic cloud formation to advanced topics like cloud microphysics and dynamics.

The Basics of Cloud Formation

Clouds form when invisible water vapor in the air condenses into visible water droplets or ice crystals. This process occurs when the air becomes saturated, meaning it can no longer hold all the water vapor it contains. The saturation point is reached when the air cools, causing the water vapor to condense around tiny particles in the atmosphere, such as dust, smoke, or salt. These particles are known as cloud condensation nuclei (CCN).
