Not sure this is in the correct category, or perhaps clouds are something I’ve never heard of in Biology?

Explanation:

A cloud in the atmosphere is just condensation appearing in the air, much like we see steam above a boiling kettle. The outcome is generally precipitation - either drizzle, rain, snow or hail dropping from the sky.

The mechanism is: warm, moist air rises, cools and condensation occurs around tiny “nuclei” such as dust in the air. There are (in principle) two main causes (i) hills forcing the air to rise (called relief precipitation) and (ii) atmospheric pressure systems moving towards each other (called frontal precipitation.)

Is that what you were looking for?
