a sunny-day tornado that forms from the ground up, no storm required

means A small, short-lived whirlwind of rotating air made visible by the dust, sand, and debris it sweeps up, typically forming on hot, calm, sunny days.

from A transparent English compound of "dust" and "devil," stitched together in the 19th century. "Dust" traces back to Old English dūst, while "devil" comes through Old English dēofol from Latin diabolus and Greek diabolos, "slanderer" or "accuser." The naming impulse is old and worldwide: cultures across deserts have seen these spinning columns as restless spirits or demons made flesh — the Arabic notion of jinn-driven whirlwinds and similar beliefs in Australia and the Americas all read the spinning dust as something alive and mischievous. English simply gave the old superstition a tidy two-word label.
