  "term": "Buoyancy frequency",
  "field": "Meteorology and atmospheric science",
  "definition": "The natural oscillation frequency of a fluid parcel displaced vertically in a stably stratified fluid, also known as the Brunt-Väisälä frequency. It represents the rate at which a parcel would oscillate if perturbed from its equilibrium level in a statically stable atmosphere or ocean. In the atmosphere, it is typically expressed in radians per second or cycles per hour.",
