Final answer:
Altostratus clouds can produce moderate surface precipitation, often in the form of light to moderate rain or snow. This type of cloud can serve as an indicator of a weather change, often preceding a storm with heavier precipitation.
Step-by-step explanation:
The student's question pertains to altostratus clouds, which are typically associated with overcast conditions and can lead to moderate surface precipitation.
Altostratus clouds are mid-level clouds that cover the sky in a blanket-like layer, and although they are not as dense as nimbostratus clouds, which are known for heavier precipitation, altostratus clouds can bring continuous and widespread light to moderate rain or snow. This type of cloud can serve as an indicator of a weather change, often preceding a storm with heavier precipitation.
