Cumulus clouds depend on the situation, indicating sunny days, unstable weather and precipitation.

When the translucent cumulus clouds don't change much, it is a sign of sunny days. When the thickness of the altocumulus is increasing and gradually merging into layers, it indicates that the weather will change and even precipitation will occur.

Semi-transparent cumulus clouds are white clouds shaped like fish scales, in rows. It is a kind of cloud layer when strong cold air comes, which indicates the recent unstable weather conditions.
