  "id": "MLC-T-MET-005583",
  "term": "Fingering",
  "field": "Meteorology and atmospheric science",
  "definition": "A phenomenon in fluid dynamics where a less dense fluid penetrates a more dense fluid in a series of narrow, finger-like intrusions, or vice versa. This instability often occurs when there are opposing gradients of two properties that affect density, such as temperature and salinity in the ocean, or temperature and humidity in the atmosphere. It contributes to mixing processes in stratified fluids.",
