Which type of clouds are typically associated with good visibility?

Cumuliform clouds, such as cumulus, are generally associated with good visibility. These clouds are characterized by their puffy, white appearance and occur in a more isolated manner rather than covering the entire sky. They typically form in fair weather conditions when the atmosphere is stable, leading to good visibility under and around them. Cumulus clouds can indicate that the air is clear and that visibility should be relatively high.

In contrast, other cloud types might be associated with poorer visibility. For instance, cumulonimbus clouds are large and can produce severe weather, including thunderstorms, which can significantly reduce visibility. Stratiform clouds often indicate overcast conditions and may be associated with light precipitation or fog, which can also impair visibility. Stratocumulus clouds are low-level clouds that can bring about varied levels of visibility but might also indicate a cap of moisture in the atmosphere that can lead to obscured conditions in certain areas. Understanding these distinctions is vital for assessing flight safety and weather conditions.
