  "id": "MLC-T-MET-010448",
  "term": "Cornice",
  "field": "Meteorology and atmospheric science",
  "definition": "An overhanging mass of snow formed by wind deposition on the leeward side of a ridge or cliff. These formations develop when wind-blown snow accumulates and compacts, extending horizontally beyond the supporting terrain. Cornices pose a hazard to mountaineers and skiers due to their instability and potential for sudden collapse, often breaking off under their own weight or external pressure.",
