What information do clouds provide regarding air conditions?

Clouds offer crucial visual reference about air movement. Different cloud types and formations can indicate various atmospheric conditions. For instance, the presence of cumulus clouds often signifies rising air, while stratocumulus clouds might suggest stable air with little vertical movement. The appearance and behavior of clouds can help pilots gauge whether the air is turbulent or stable, providing important information for flight safety and decision-making. This understanding is vital for pilots to navigate effectively and anticipate weather changes during their flight. Other options, while they might present certain aspects of weather and flying, do not encompass the broader significance of clouds as indicators of air movement.
