  "id": "MLC-T-MET-004395",
  "term": "Closed circulation",
  "field": "Meteorology and atmospheric science",
  "definition": "An atmospheric flow pattern where streamlines or isobars form complete closed loops around a central pressure system, such as a low-pressure cyclone or a high-pressure anticyclone. This indicates a well-defined and often persistent circulation feature that is largely isolated from the surrounding atmospheric flow. Closed circulations are common in mature tropical cyclones.",
