  "field": "Meteorology and atmospheric science",
  "definition": "A small, cap-like cloud formation that appears above or attached to the top of a rapidly growing cumulus or cumulonimbus cloud.

Pileus clouds are indicative of intense convection and often precede the development of thunderstorms.",
