What characteristic do ACC clouds exhibit?

ACC clouds, or altocumulus clouds, are typically characterized by their structure, which often includes laminae (thin layers) and rounded masses or patches. This layered appearance gives them a unique texture that differentiates them from other cloud types.

The presence of laminae indicates that these clouds can form in distinct layers, while the rounded masses contribute to their fluffy, puffy appearance. This structure can provide visual cues to pilots about the atmosphere, including potential turbulence or changes in the weather.

Other descriptions, such as solid sheets or consistent thickness, do not accurately capture the variability and structure that define ACC clouds. Additionally, describing them solely as fibrous does not encompass the full range of their visual characteristics, which include both layered and rounded forms. Overall, the description of ACC clouds as composed of laminae and rounded masses is the most accurate representation of their typical appearance.
