  "id": "MLC-T-MET-007891",
  "term": "Phase instability",
  "field": "Meteorology and atmospheric science",
  "definition": "A condition in a thermodynamic system where a small perturbation can cause a substance to spontaneously change its phase. This occurs when the system is in a metastable state, such as supercooled water or supersaturated vapor. Phase instability is a key concept in understanding the initiation of precipitation in clouds.",
