Question

Why does the height of the cumulus cloud base change from day to day?

Answer 1

Answer:

The humidity of the air and the temperature vary from day to day. Rising air cools to the dew point above which level cloud will form. If the air is drier at the surface or the air is hotter when it starts rising, the base of the cloud will be different from the previous day. If the temperature and dew point are the same on consecutive days, the cloud base will be the same.

Answer 2

Answer:

Cumulus clouds are clouds which have flat bases and are often described as "puffy", "cotton-like" or "fluffy" in appearance. Their name derives from the Latin cumulo-, meaning heap or pile.[1] Cumulus clouds are low-level clouds, generally less than 2,000 m (6,600 ft) in altitude unless they are the more vertical cumulus congestus form. Cumulus clouds may appear by themselves, in lines, or in clusters.
