  "id": "MLC-T-MET-004394",
  "term": "Closed cells",
  "field": "Meteorology and atmospheric science",
  "definition": "A pattern of mesoscale cellular convection in which cloud-filled cells, often polygonal, are ringed by narrow cloud-free borders, seen in satellite images of stratocumulus. Air rises in the cloudy center and sinks at the clear edges. Closed cells occur over cool ocean water under a strong inversion, while open cells with clear centers form in colder air moving over warmer water.",
