  "term": "Thunderstorm outflow",
  "field": "Meteorology and atmospheric science",
  "definition": "A surge of cool, dense air that spreads horizontally away from the base of a thunderstorm, generated by the downdraft of precipitation-cooled air. This outflow boundary can act as a miniature cold front, lifting warm, moist air ahead of it and potentially triggering new thunderstorms. It is often visible as a shelf cloud or roll cloud.",
