  "id": "MLC-T-MET-008242",
  "term": "Quasigeostrophic approximation",
  "field": "Meteorology and atmospheric science",
  "definition": "A set of simplifications applied to the primitive equations of atmospheric motion, assuming that the flow is nearly geostrophic and hydrostatic. This approximation filters out high-frequency gravity waves, allowing for a focus on synoptic-scale weather systems. It is a fundamental tool in theoretical meteorology for understanding large-scale atmospheric dynamics.",
