What altitude range classifies clouds as middle clouds?

Middle clouds are classified specifically as those that exist in an altitude range of 6,500 to 20,000 feet. This classification is due to their formation processes and characteristics, which differ from lower and upper cloud types. Middle clouds typically consist of water droplets, which may blend with ice crystals at the higher ends of their altitude range. They often manifest as altostratus and altocumulus clouds.

Understanding the altitude classification of clouds is essential for pilots because different cloud types can significantly affect flying conditions. For example, middle clouds can indicate weather systems, moisture, and potential turbulence. Unlike lower clouds, which are generally more associated with precipitation, middle clouds can denote stable conditions or serve as precursors to upper-level weather phenomena, making their identification critical for flight planning and safety.
