a wall of desert that walks, swallowing cities and daylight in one apocalyptic shrug

means A haboob is an intense, towering dust or sand storm driven by the outflow winds of a collapsing thunderstorm, often arriving as a dense rolling wall that blots out the sky.

from From Arabic habūb (هبوب), meaning 'blowing' or 'blasting wind,' from the root h-b-b 'to blow.' The word entered English through observations of these storms in Sudan, especially around Khartoum, and was later borrowed wholesale to describe similar dust walls in deserts elsewhere, including the American Southwest.
