  "id": "MLC-T-MET-005452",
  "term": "Equivalent barotropic level",
  "field": "Meteorology and atmospheric science",
  "definition": "A specific atmospheric level, often around 500 hPa, where the horizontal wind flow is approximately non-divergent and representative of the vertically averaged flow in a barotropic atmosphere. At this level, the wind direction does not change significantly with height, simplifying the analysis of large-scale atmospheric motions. It is a concept used in simplified atmospheric models.",
