A cloud sequence of cirrus, cirrostratus, and altostratus clouds followed by rain usually signifies the approach of a(n) _______________.
AI Explanation
The correct answer is D) warm front.
The sequence of cloud types - cirrus, cirrostratus, and altostratus clouds followed by rain - is indicative of the approach of a warm front. As a warm front advances, the warmer, moisture-laden air rises over the cooler air, causing the formation of these high- and mid-level cloud types, and eventually precipitation as the front passes.
The other options are incorrect because: A) a stationary front does not have a defined direction of movement, B) an occluded front is a more complex system formed by the merger of a cold and warm front, and C) a cold front is characterized by a different cloud sequence and rapid weather changes.
