{
  "id": "MLC-T-MET-004795",
  "term": "Cumulonimbus calvus",
  "field": "Meteorology and atmospheric science",
  "definition": "A cumulonimbus cloud that has not yet developed a fibrous or striated upper part, meaning its top still appears rounded and puffy, similar to a large cumulus congestus. This stage indicates that the cloud's updraft is strong but has not yet reached the level where ice crystals fully dominate and spread out. It is a precursor to the more mature cumulonimbus capillatus stage.",
