  "field": "Meteorology and atmospheric science",
  "definitions": [
    "A small, rotating column of air made visible by dust, sand, or other light debris, primarily occurring over arid or semi-arid regions. It forms on clear, hot days when intense solar heating of the ground creates a layer of highly unstable air that begins to spin as it rises. This phenomenon is meteorologically identical to a dust devil and is not associated with a parent thunderstorm.",
    "In Australia, a dust devil. Also formerly used to denote a tropical cyclone."
